The botany of the Cunene-Zambezi expedition with notes on Hugo Baum (1867-1950)

WOS:000275977600005 (Nº de Acesso Web of Science)A record and discussion of the Cunene-Zambezi Expedition that took place in Angola from 1899 to 1900 is provided. Although the main aim of the expedition was to evaluate the economic potential of southern Angola, it also resulted in significant botanical collections made by Hugo Baum (1867-1950), many of which serve as holotypes of names of plants from the region, and beyond. The itinerary is supplemented by a map illustrating the route followed by the expedition, and locality names are clarified and updated. A full list of the type specimens of flowering plants is provided, with their nomenclature updated and an indication of where known duplicates are housed

Five New Species Of Dichorisandra J. C. Mikan (commelinaceae) From Bahia State, Brazil

Summary: Five new species of the genus Dichorisandra J. C. Mikan are described based on field, herbarium and cultivation studies. The species described here are only known from the Atlantic rain forest from the State of Bahia, Brazil and have anthers with introrse longitudinal slits that are functionally poricidal. D. subtilis Aona & M. C. E. Amaral is characterised by its small habit, erect, densely pilose leaves, flowers in congested inflorescences, 5 stamens and a verrucose ovary. D. variegata Aona & Faden presents terminal, erect or sometimes decumbent inflorescences sprouting from the base of the plant, leaf blades sparsely to densely pilose and with two white longitudinal broad stripes above, and 5 (- 6) stamens. D. jardimii Aona & M. C. E. Amaral is characterised by the axillary inflorescences that perforate the leaf sheaths and arise either directly from the rhizome or from normal terrestrial branches, 5 stamens, a verrucose ovary and cylindrical fruits. D. ordinatiflora Aona & Faden presents axillary inflorescences that perforate the leaf sheaths, inflorescences distributed evenly along the stem, and a reddish indumentum. D. conglomerata Aona & M. C. E. Amaral can be recognised by its completely glabrous leaves, terminal inflorescences, the large number of flowers per cincinnus (7 - 10 flowers), and 5 stamens. Discussion of relevant characters, comparisons with closest relatives, descriptions, information on conservation status and illustrations are provided. © 2012 The Board of Trustees of the Royal Botanic Gardens, Kew.664479491Aona, L.Y.S., (2008) Revisão taxonômica e análise cladística do gênero Dichorisandra J.
