The Identity of Diplospora Africana (Rubiaceae)

Robbrecht Nationale Plantentuin van Belgie, Domein van Bouchout, Meise, Belgium Diplospora africana Sim is shown to be a distinct species Introduction belonging to Tricalysia subg. Empogona sect.

When Sim (1907) dealt with Tricalysia in the Cape, he did It possesses the characteristics of this subgenus: Flowers not follow the delimitation of the genus proposed in with densely hairy corolla throat and appendiculate anthers, and fruits black at complete maturity. The necessary Schumann's (1891) account of the family (i.e. Diplospora and combination under the name Tricalysia and an amplified Kraussia are considered as sections of Trica/ysia) , but description of the species are provided.

The ecologically rich environment and the multi-ethnic integration provide a valuable foundation and driving force for high biodiversity and cultural diversity in this region. -
Vestured Pits in Wood of Onagraceae: Correlations with Ecology, Habit, and Phylogeny1
VESTURED PITS IN WOOD OF Sherwin Carlquist2 and Peter H. Raven3 ONAGRACEAE: CORRELATIONS WITH ECOLOGY, HABIT, AND PHYLOGENY1 ABSTRACT All Onagraceae for which data are available have vestured pits on vessel-to-vessel pit pairs. Vestures may also be present in some species on the vessel side of vessel-to-ray pit pairs. Herbaceous Onagraceae do not have fewer vestures, although woods with lower density (Circaea L. and Oenothera L.) have fewer vestures. Some Onagraceae from drier areas tend to have smaller vessel pits, and on that account may have fewer vestures (Epilobium L. and Megacorax S. Gonz´alez & W. L. Wagner). Pit apertures as seen on the lumen side of vessel walls are elliptical, occasionally oval, throughout the family. Vestures are predominantly attached to pit aperture margins. As seen from the outer surfaces of vessels, vestures may extend across the pit cavities. Vestures are usually absent or smaller on the distal portions of pit borders (except for Ludwigia L., which grows consistently in wet areas). Distinctive vesture patterns were observed in the several species of Lopezia Cav. and in Xylonagra Donn. Sm. & Rose. Vestures spread onto the lumen-facing vessel walls of Ludwigia octovalvis (Jacq.) P. H. Raven. Although the genera are presented here in the sequence of a recent molecular phylogeny of Onagraceae, ecology and growth forms are more important than evolutionary relationships with respect to abundance, degree of grouping, and morphology of vestured pits. Designation of vesture types is not warranted based on the distribution of named types in Onagraceae and descriptive adjectives seem more useful, although more data on vesturing in the family are needed before patterns of diversity and their extent can be fully ascertained. -

Epilist 1.0: a Global Checklist of Vascular Epiphytes
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2021 EpiList 1.0: a global checklist of vascular epiphytes Zotz, Gerhard ; Weigelt, Patrick ; Kessler, Michael ; Kreft, Holger ; Taylor, Amanda Abstract: Epiphytes make up roughly 10% of all vascular plant species globally and play important functional roles, especially in tropical forests. However, to date, there is no comprehensive list of vas- cular epiphyte species. Here, we present EpiList 1.0, the first global list of vascular epiphytes based on standardized definitions and taxonomy. We include obligate epiphytes, facultative epiphytes, and hemiepiphytes, as the latter share the vulnerable epiphytic stage as juveniles. Based on 978 references, the checklist includes >31,000 species of 79 plant families. Species names were standardized against World Flora Online for seed plants and against the World Ferns database for lycophytes and ferns. In cases of species missing from these databases, we used other databases (mostly World Checklist of Selected Plant Families). For all species, author names and IDs for World Flora Online entries are provided to facilitate the alignment with other plant databases, and to avoid ambiguities. EpiList 1.0 will be a rich source for synthetic studies in ecology, biogeography, and evolutionary biology as it offers, for the first time, a species‐level overview over all currently known vascular epiphytes. At the same time, the list represents work in progress: species descriptions of epiphytic taxa are ongoing and published life form information in floristic inventories and trait and distribution databases is often incomplete and sometimes evenwrong. -

Pollen tube growth rates (PTGRs) of angiosperms are exceptionally rapid, a pattern 25 attributed to more effective haploid selection under stronger pollen competition. Paradoxically, 26 whole genome duplication (WGD) has been common in angiosperms but rare in gymnosperms. -

Cytological Observations on Some West Himalayan Orchids Tribe: Epidendreae I (Subtribes: Pogoniinae, Thuniinae, Bletiinae, Coelogyninae, Epidendrinae)
Cytologia 49: 583-595, 1984 Cytological Observations on Some West Himalayan Orchids Tribe: Epidendreae I (Subtribes: Pogoniinae, Thuniinae, Bletiinae, Coelogyninae, Epidendrinae) P. N. Mehra and S. K. Kashyap Department of Botany, Panjab University, Chandigarh, India Received October 20, 1982 Epidendreae is the largest tribe of the family Orchidaceae with 29 subtribes covering about 465 terrestrial and epiphytic genera. A great majority of them belong to the subtribes Sarcanthineae, Oncidiinae and Epidendrinae. All the genera with few exceptions possess hard and waxy pollinia which is genrally accepted to be an advanced character in the family Orchidaceae. The systematics of some of the genera is highly debatable. Bulbophyllum Thou. and Dendrobium Sw. with about 1400 species each belong to this category. Most of the epiphytic as well as terrestrial members of this tribe have great horticultural value for their fascinating flowers. Cytological information is still quite meagre considering its great numerical strength. Important contributions on the subject have been made by many workers (cf. Moore 1973, Tanaka and Kame moto 1972, 1974). Contributions on the Indian members of the tribe have been made by Sharma and Chatterji (1966), Vij and Mehra (1976), and Mehra and Sehgal (1974, 1975, 1976, 1978, 1980). Presently cytological investigations have been carried out on 56 West Himalayan species belonging to 26 genera included in 10 subtribes. These results are presented in a series of three papers. The present paper includes 14 species under 8 genera. Discussion, conclusions, and phyletic relationships of the tribe Epidendreae as a whole is presented in the last paper of the series. Material and methods All the taxa studied were collected in nature. -
