Abstract:

Three new Magnolia species and a new record from Guatemala are described and illustrated. Two of the new species, M. javieri and M. oscarrodrigoi, are from Alta Verapaz Department and one, M. veliziana, is from Quiché Department. Additionally, M. faustinomirandae is newly reported for the flora of Guatemala. With this contribution, the number of native Guatemalan species increases from 11 to 15 species. An updated distribution map and a key to species are provided. Guatemala, particularly the north-wet-arc in the Maya Highlands, is now an important centre of diversification and endemism for Ma

While studying the diversity of this plant group in the department of Baja Verapaz, we found individuals that clearly belonged to the genus Schiedeella, but whose features did not fit any previously known species. At that time, nine terrestrial taxon representatives were known to occur in Guatemala. We conducted the morphological analysis in accordance with the standard procedures of classica

The taxonomy of this host in Chiapas is controversial as Perry (3) classifies the Chiapas populations of this pine as Pinus oocarpa var. ochoterenai Martinez.

The known distribution of <em>Bothriechis aurifer</em> (Salvin, 1860) is outdated, which impedes an accurate evaluation of its conservation status. Here, we clarify the locality-level distribution of <em>B. aurifer </em>and announce a 101-km range extension. Based on this and other data, we recommend its recategorization as Endangered under the International Union for Conservation of Nature’s Red List of Threatened Species, and its addition to Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora.

Floral initiation in coffee has been shown to be stimulated by short days in young plants, but the inductive stimulus for mature plants is still not clear. Experiments were conducted to determine whether floral initiation in immature and mature plants is promoted by short photoperiods, and delayed by long photoperiods. In a growth chamber study, 18-month-old coffee (Coffea arabica L. cv.

The species was previously accepted only for South America. We provide a description of the species, a distribution map, and a key to distinguish it from S. microstachyum and S. condensatum, species whose circumscriptions are confused in floras of Central America and West Indies.

Our results on investment in pollen relative to ovule production are consistent with E. tithymaloides relying on pollinators for reproduction across its range in the Caribbean.

The duration from sowing to flowering is an important determinant of fibre yield in kenaf. Accordingly, the effect of temperature and photoperiod on the phenology of kenaf was examined.
