Resumen

A new phytochemical study of Mortonia greggii (Celastraceae) afforded four friedelan derivatives (1-4), three lupanes (5-7), retusine (8), two esterified polyhydroxyagarofurans (9-10), mortonin C (11) and photomortonin C (12). The anti-inflammatory activity on carrageenan and 12-O-tetradecanoylphorbol-13-acetate induced models of inflammation, as well as the ability to inhibit the nitric oxide (NO) produced by lipopolysaccharide-stimulated mouse peritoneal macrophages were evaluated for the main metabolites. Our results showed that the friedelan dehydrocanophyllic acid methyl ester (1) exhibits an anti-inflammatory effect which could be related to an inhibition of prostaglandin and NO production. The activity of lupeol (5), 29-hydroxylupeol (6) and 29-hydroxylupenone (7) might be involved with the prostanoid synthesis. The presence of the hydroxy groups in 6 appears to be important for activity. The edema inhibition capacity of retusine (8) could be related to a reduction of the prostaglandin production. The agarofuran derivative 10 is an NO inhibitor whose activity is probably not involved in the synthesis of prostaglandins.

Resumen

The AssociationDrepanoclado Uncinati-Heliospermetum Pusilli (Arabidetalia Caeruleae, Thlaspietea Rotundifolii)in the Trnovski Gozd Plateau (Slovenia, NW Dinaric Mts)The phytosociology and ecology ofHeliosperma pusillumin freezing ravines of the Trnovski gozd plateau (Slovenia, NW Dinaric Mts) are discussed. The species thrive on shadowy, moist, cold and stable screes of boulders with long-lasting snow cover. The stands belonged to the associationDrepanoclado uncinati-Heliospermetum pusilli (Salicion retusae, Arabidetalia caeruleae, Thlaspietea rotundifolii). Due to close proximity to the Julian Alps, the stands host a significant number of SE - Alpine and N-Illyrian species. Therefore, a new geographical variantPaederota luteais described. Differential species for the geographical variant arePhyteuma scheuchzerissp.columnae, Valeriana saxatilis, Rhodothamnus chamaecistus, andSaxifraga cuneifolia.For less stable screes with smaller rocky particles a new subassociationsalicetosum retusaeis described, and the differential species for the subassociation areSalix retusaandPoa alpina.Stands of the associationDrepanoclado-Heliospermetumvar. geogr.Paederota luteafrom the Trnovski gozd plateau are on the north-westernmost part of the distribution area of the Dinaric allianceSalicion retusae.

Resumen

An alkaloid of Crotalaria leschenaultii DC., previously reported as crispatine and now named crotaleschenine, has been re-investigated and shown to be (7β,8α-H,12α,13α,14α)-12β-hydroxy-1,2-didehydrocrotalane-11,15-dione.1 Spectroscopic data are presented and the stereochemistry determined by X-ray crystallography. The esterifying acid of crotaleschenine is identical with that of retusine , which is thereby determined as (1a,7β,8α-H,12α,13α,14α)-12β- hydroxycrotalane-11,15-dione.

Resumen

A new fully myco-heterotrophic orchid, Gastrodia damingshanensis, is described and illustrated from Damingshan National Nature Reserve in Guangxi, China. The new species is significantly distinct from the otherwise similar G. uraiensis and G. fontinalis by its much longer peduncle, the shortened column hidden by the lip, and the reddish brown, rhombic-elliptic lip with a slightly retuse apex. This new species is predicted to be obligatory self-pollinated due to the specialized column structure which allows the pollinia directly touching the stigma.

Resumen

Silene lulakabadensis Heidari, F. Ghahrem. & Assadi is described as a new species from Zanjan Province, Iran. The new species is a dark green plant, perennial and woody at the base, that was collected on marl soil slopes at 2100 m. It is believed to be closely related to S. eriocalycina Boiss. from section Auriculatae (Boiss.) Schischk. but is a smaller plant, with much shorter internodes, and pinkish-white retuse to emarginate petals with very small or no scales. It is a very rare plant and its conservation status is assessed as Critically Endangered.

Resumen

A new species of Mikania from the northern area of the Western Cordillera of Colombia is described and illustrated. Taxonomic affinities with its closest relatives M. lloensis and M. flabellata are discussed. The diagnostic traits of the new species are: the long peduncle of the synflorescence; the size of the head; the presence of a midvein in the corolla lobes; the presence of moniliform, multicelular, uniseriate trichomes below the commissural sinuses of the corolla lobes; the insertion of the stamens at the mid-level of the hypocrateriform corolla; and the retuse apical appendages of the anthers. The latter trait is newly used here as diagnostic in the genus.

Resumen

AbstractA small, endemic leafy liverwort found in the coastal redwood forests of Santa Cruz and Monterey Counties of California is described as a new species of Mesoptychia (Lindb.) A. Evans, i.e., Mesoptychia polymorpha Stotler, Crand.-Stotl. & Bakalin, sp. nov. This new taxon is morphologically related to the suite of small-leafed species of the genus, including M. badensis (Gottsche ex Rabenh.) L. Söderstr. & Váňa and M. morrisoncola (Horik.) L. Söderstr. & Váňa, but is unique within the genus in having mature vegetative leaves and bracts that are undivided and apically rounded to emarginate, with bilobed to retuse leaves of restricted occurrence. Although this polymorphic species is paroicous, perianths expand without fertilization and sporophytes are unknown.

Resumen

A new species of Chrysopogon from the lateritic hillocks of Kannur District, Kerala, India, is described and illustrated. It closely resembles C. tadulingamii, but differs mainly in having sessile spikelets with a ciliate, short-awned upper glume and a short-awned upper lemma, pedicelled spikelets with 7-nerved, awned lower glume, a short 3-nerved awnless, retrorsely ciliate upper glume and a retuse or bifid upper lemma. The new species also resembles C. asper in some characters, but differs in having acicular or linear leaf blades, rounded leaf sheaths, and sessile spikelets with short-awned upper glume and upper lemma. A key for identification of species in Chrysopogon from Kerala is also provided.

Resumen

Based on fieldwork and an extensive analysis of herbarium and type collections, a new species which grows in sedimentary soil in the Brazilian semiarid region, Erythroxylum pyan (Erythroxylaceae), is described here. The new species occurs in areas of hyperxerophilic caatinga in the states of Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, and Bahia. Erythroxylym pyan resemble E. nummularium, but can be distinguished by having slender branches, foliar stipules non-striated longitudinally, 2-setulose at apex, leaf blades membranous to slightly chartaceous, emarginate to retuse at apex, inflorescences with 1 flower per node, long, slender and erect pedicels, and calyx lobes cuspidate at apex. Additionally, a distribution map and data about its phenology, conservation status, and uses are provide.

Resumen

Bauhinia includes about 150 species distributed across the tropics. Most Neotropical species belong to Bauhinia ser. Cansenia that includes unarmed trees and shrubs, mostly from areas under seasonally dry climate. A new species of this series is described here from the northeastern Brazilian states of Bahia and Sergipe. Bauhinia corifolia occurs in open vegetation on sandy soils of Restinga vegetation at the Atlantic coastal forests. It is morphologically similar to B. acuruana by sharing the entire and ovate leaflet with a retuse to emarginate apex and a cordate base, but differing by its tall shrub to treelet habit, larger leaves with a glabrous and glossy upper surface, shorter bracts, and longer flowers. We provide description, illustration and distribution map for the new species.

Resumen

A biologically guided isolation of secondary metabolites from Cousinia alata Schrenk wild plant growing in Akmola region, Kazakhstan, led to the isolation of the bioactive diterpene grindelic acid (1). Six flavonoids were also isolated and identified as retusine (2), pachipodol (3), jaranol (4), penduletin (5), casticin (6), and 5, 7, 3′-trihydroxy-3, 4′-dimethoxyflavone (7). Penduletin (5) showed moderate cytotoxic activity assay. Grindelic acid exhibited promising cytotoxic activity against the Artemia salina nauplii and antibacterial activity against Staphylococcus aureus, Bacillus cereus, and Salmonella enteritidis. The presence of the essential pharmacophoric features of histone deacetylase (HDAC) inhibitors in the structure of grindelic acid encouraged us to run a molecular docking study against the HDAC enzyme to understand its mechanism of action on a molecular level. Grindelic acid showed a binding mode of interaction similar to that of the cocrystallized ligand and exhibited good binding affinity against HDAC with the binding free energy of −18.70 kcal/mol. The structures of isolated compounds were determined by MS, 1D, and 2D NMR spectroscopy methods. Compounds (1–7) were isolated for the first time from Cousinia genus.

Resumen

There are described, illustrated and compared to similar taxa Eugenia caatingicola, E. funchiana, E. coccinea and E. potiraguensis. The first three species occur in areas of caatinga (dryland) vegetation (Bahia and Piauí states),while E. potiraguensis is encountered in the Atlantic Forest (Bahia), Brazil. Eugenia caatingicola can be distinguished from Eugenia subreticula by the texture of the periderm of the older branches, leaf apices retuse, and hypanthium sericeous. Eugenia funchiana is similar to E.dentata, but have undulate leaves, smaller petioles and pedicels, and hypanthium not costate. Eugenia coccinea differs from E. duarteana by having membranaceous leaves, calyx lobes with reddish trichomes at apex, and hypanthium glabrous. Eugenia potiraguensis differs from E. plicata by having central veins glabrous, larger petioles, and calyx lobes equal between them. Additionally, each species is evaluated in its conservation status.

Resumen

Fornication and Other “Awful Sins” in the Bible Translations. Euphemisms and Alterations on Matt 5:32, 9:19 and Lev 20:10-21 The paper shows confusion of theologians – both catholic and protestant – in all Polish and many other translations of fragments related to sexual relations, especially these contacts which were recognised uniquely as a cause of divorce. The considered translations tend to use archaic, euphemistic or imprecise vocabulary in the main text, adding often confusing and linguistically unacceptable footnotes. On the contrary, the analysed Italian and French translations are clear and intelligible. The Author shows, nevertheless, that the existing translations – not only in Polish, but also in Italian and French – of the Greek word porneia used in the Gospels are incoherent with those in the Old Testament, which is unacceptable. The Author also claims, on the basis of analysed texts, that even the best footnotes cannot replace a clear and intelligible translation in the main text.

Resumen

Dichocarpum hagiangense from Ha Giang province, northern Vietnam is described and illustrated. Diagnostic features of the new species are a short rhizomatous stem, (2–)3-foliolate or simple leaves, and pink-purple flowers. The described species is distinct from closely allied D. trifoliolatum in having longer sepals, shape and obcordate apex of petal limbs, shorter flower stem, number and tooth shape of basal leaves; it differs from D. basilare and D. carinatum in having stem leaf, retuse apex and longer of central leaflet, number and (2–)3-foliated (or simple) of leaf. With the support of molecular data, the new species was clearly distinguished from other species in the Dichocarpum group by eight autapomorphic characters in nrITS sequence. A key to all species of Dichocarpum is provided. We suggest the IUCN conservation status of D. hagiangense to be “Critically Endangered”. A newest checklist of the family Ranunculaceae in Vietnam is updated.

Resumen

We document diagnostic characteristics of Roegneria by which it differs from genera with which it has often been confused. Characteristics of Roegneria are the absence of underground runners; slightly curved and elongated rachis with long internodes, each rachis node bearing one spikelet only and often adhering to the internode, and inflorescence appearing more or less one sided because of the disposition of the spikelets; spikelet functionally disarticulating below the glumes; glume symmetric with nerves tapering in the apex; lemma with nerves tapering in the apex; and palea generally shorter than the lemma, and if equal to the lemma then the tip obtuse, truncate, or retuse. Genera difficult to separate from Roegneria are Agropyron, Elymus, and Elytrigia; these share one or more characteristics but none have them in the same combination. We also stress the merit of recognizing Roegneria for germ-plasm utilization. Key words: Roegneria, Triticeae, generic limits, Elymus, Agropyron, Elytrigia.

Resumen

Ruellia anamariae, a new species of Acanthaceae is herein described and illustrated from the municipalities of Parauapebas and São Geraldo do Araguaia, Pará State, Brazil. The new species is recognized by its habit, a shrub up to 5 meters high, by its terminal thyrsus inflorescence, by its greenish-yellow corolla with the expanded portion of the tube suburceolate, strongly revolute lobes and shortly exserted stamens. It is also morphologically similar to Ruellia exserta, but differs by its habit, a shrub (not liana), inflorescence, thyrsus with opposite dichasia (not secundiflorous thyrsus) and short exserted stamens (not long exserted), and to Ruellia beckii differing by its habit, a shrub (not liana) end calyx lobes oblong-lanceolate with acute apex (not oblanceolate to obovate with retuse to obtuse apex). We provide a detailed description, illustrations, comments, data on distribution and habitat and conservation status of the species.

Resumen

A new species, Bredia malipoensis D. H. Peng, S. Jin Zeng & Z. Y. Wen, from China, is described and illustrated here. Bredia malipoensis is morphologically similar to B. longiradiosa C. Chen in having cordate leaf blades, umbellate inflorescence and undulate petals with unguiculate bases and retuse apices. It is characterized by its terete stem and petioles, green calyx lobes, purple anthers, yellow connective appendages and white filaments. It is also morphologically similar to B. velutina Diels in having a woody stem, unequal and cordate leaf blades, but it is differentiated by having no reddish trichomes, larger and semiorbicular calyx lobes, and unguiculate petal bases. Bredia malipoensis differs markedly from the former relatives by its densely tomentose indumentum (with uniseriate non-glandular and sparse glandular trichomes) both on vegetative and floral parts, basal leaf venation and purplish-red petals. Our phylogenetic analyses using nuclear ribosomal ITS and chloroplast trnV-trnM regions strongly support the generic placement of B. malipoensis and its relatives B. longiradiosa and B. velutina within Bredia.
