Abstract:

Diversities in the pollinia morphology of the family Asclepiadaceae in respect to pollinium shape, size, color, length and breadth of pollinial sac, length and breadth of corpusculum and length and breadth of caudicle were studied in 13 species belonging to eight genera (Cynanchum L., Calotropis R.Br., Glossonema Decaisne., Leptadenia R.Br., Pergularia L., Sarcostemma R.Br., Tylophora R.Br and Vincetoxicum N. M. von Wolf.) Calotropis procera (Ait.) Ait. f. yielded largest pollinia sac. (906.4 4.4.7 ?m) whilst the smaller one (109.8 × 48.0 ?m) was represented by Cynanchum pollens Hemsley and La

Abstract:

In this study, the pollen morphology of 20 representatives of ten taxa of Vincetoxicum from Turkey was observed under a scanning electron microscope and light microscope. Observations showed that each flower contained five pollinaria, including a pair of pollinia and caudicles attached to a central corpusculum. In the investigated taxa, the shape of the pollinium varied from ovate, elliptical, and obovate, to clavate, pollen cell surfaces exhibited gemmate or rugulate ornamentation, and the shape of the corpuscula was ovate or oblong.

Abstract:

Abstract— Molecular phylogenetic studies have been the basis for major clades proposed for the Aeridinae subtribe of the Orchidaceae family. However, systematic morphological characterization has yet to be conducted. We carried out this study on Aeridinae pollinium morphologies with an emphasis on aperture type and pollinium sculpturing to determine the systematic significance of these characteristics in the context of molecular phylogenetics. The results indicated that most Aeridinae species have cleft type pollinium apertures and that few have porate type or no aperture. The shapes of most o

Abstract:

Caladenia behrii Schltdl. (Orchidaceae) (syn. Arachnorchis behrii) is a sexually deceptive, endangered orchid that produces aggregated pollen as pollinia. It is pollinated by a thynnine wasp, and may also be pollinated incidentally by other insects. Pollinator effectiveness may depend on the number of pollinia that pollinators carry and deposit, and on whether they mediate cross-pollination or self-pollination. To understand the role of pollinators and guide conservation programs, we determined the effect of pollen load (one pollinium v. two pollinia) and self-pollination on seed number, seed

Several species of insects captured while feeding on flowers of the legumes Daviesia virgata and D. mimosoides carried pollinia of the orchid Diuris maculata on their heads. In contrast, insects were difficult to capture on Diuris maculata due to the very low frequency and short duration of visits. More pollinaria were removed from the flowers than pollinia deposited. Pollen loads carried by insects bearing orchid pollinia were almost exclusively from Daviesia spp. and Pultenaea scabra.

Abstract:

Orchidaceae display enormous diversity in their flower morphology, which is particularly evident in their pollen dispersal units (pollinia, pollinaria). The packaging of pollen by elastoviscin leads to a great diversity of these morphologically and structurally complex pollen units. Despite being one of the most diverse angiosperm families, the available palynological data on orchids remain limited and sometimes contradicting. This study provides new insights into the pollen morphology and ultrastructure of five orchid species from the subfamily Epidendroideae, using combined light, scanning e

Abstract:

Pollination of D. speciosum is effected by the deposit of the pollinia from one flower into the stigmatic cup of a flower on another plant. The pollinia are submerged into the viscous liquid of the stigmatic cup. This liquid contains the detached stigmatic cells and mucilage. Post-pollination phenomena within this species include a more intense perianth colour and the closure of the perianth. This is followed by the swelling of the column and ovary and, after 4 days, cell division in the ovary. Following pollination the pollinia break apart as the tetrads dissociate from each other.

Abstract:

Mating success in plants depends largely on the efficiency of pollen dispersal. For hermaphrodite plants, self-pollination, either within or among flowers, can reduce mating opportunities because of pollen and ovule discounting and inbreeding depression. Self-pollination may be particularly detrimental in plants such as orchids and asclepiads that package each flower's pollen into one or more pollinia which, together with accessory structures, comprise a pollinarium. Darwin proposed that physical reconfiguration of pollinaria serves as a mechanism for reducing the likelihood of self-pollinatio

We investigated whether this pollination strategy may also be operating in Pterostylis species in New Zealand where generalised plant–insect pollination strategies are most commonly documented.

Abstract:

Danxiaorchis yangii (Calypsoinae, Epidendreae, Epidendroideae), a holomycotrophic new species from Jinggangshan National Nature Reserve, western Jiangxi, eastern of China, is here illustrated and described based on both morphological and phylogenetic evidences. The new species can be easily distinguished from D. singchiana by its much smaller flowers and larger Y-shaped callus adaxially bearing a additional obovoid appendage, and by its four pollinia narrowly elliptic in shape and equal in size.

Abstract:

Gastrochilus dulongjiangensis, a new species from Gaoligongshan National Natural Reserve, Yunnan, China, is described here. It is morphologically similar to G. pseudodistichus and G. fuscopunctatus, but can be distinguished from them by having the orbicular epichile, hypochile as wide as epichile and fusiform pollinia. A preliminary risk-of-extinction assessment shows that the new species should be regarded as Data Deficient (DD) according to the IUCN Red List Categories and Criteria.

Abstract:

Vincetoxicum xinpingense, a new species from the Ailao Mountains in Yunnan Province, China, is described and illustrated. It is morphologically similar to V. sublanceolatum, Tylophora forrestii, and T. chingtungensis, but can be distinguished by several characters: shape and size of leaves, size of corolla lobes, length and shape of corona, attachment position of corona to the anthers, and orientation of pollinia. In addition, conservation status and other relevant notes are provided.

Abstract:

A new genus Cymbidiopsis H.J.Chowdhery, with 2 species – C. macrorhiza (Lindl.) H.J.Chowdhery and C. lancifolia (Hook.) H.J.Chowdhery is described. Cymbidiopsis is allied to Cymbidium Swartz but differs in habit, vegetative characters as well as in flower structure. Besides unlike the genus Cymbidium, Cymbidiopsis has flowers with 4 pollinia in 2 unequal pairs and lip with 2 callus ridges converging to form a short tube at the base of the mid-lobe.

Abstract:

Stereochilus Lindley (1858: 38) is a small orchid genus of about seven species distributed from northeastern India to Vietnam (Govaerts et al. 2019). It is characterised by a long, erect footless column with firmly attached saccate lip, long subulate rostellum projection and long slender somewhat clavate stipes with a small viscidium carrying four equal, ovate pollinia with short caudicles, the sac inside with back wall callus, front wall callus and septum (Seidenfaden 1988).

Abstract:

Hygrochilus and Sedirea are genera of orchids with only three species endemic to Asia. An analysis of ITS and five plastid regions using parsimony, maximum likelihood, and Bayesian methods obtain clear evidence that Sedirea is nested within and should be considered synonymous with Hygrochilus. We adopt a broadly defined Hygrochilus characterized by possession of four pollinia. A new combination, namely, Hygrochilus japonica, and a new species, namely, Hygrochilus tsii (Orchidaceae: Epidedroideae: Aeridinae), are proposed.

Anther primordium initiated as a homogenous mass of meristematic cells which developed two thecae, each with a group of archesporial cells of dense cytoplasmic contents. The sporogenous cells of the hypodermal layer formed the anther wall which was 4-5 layered in S. sinensis and 7-layered i

Abstract:

Floral morphological diversity and phylogenetic relationship were studied in the family Asclepiadaceae. This family characterized by unique features that contributes to extreme floral complexity and diversity. In this paper, we used preliminary phylogenetic hypothesis for the family Asclepiadaceae to explore the mode of diversification in pollinarium and coronal structure. The occurance, size, shape, position, orientation of pollinia, mode of pollination and the presence of form of coralline corona and gynostegial corona were studied for similarity indices between two subfamilies Periplocoidea

Full text

Abstract:

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.
