The tribe Hippomaneae (Euphorbiaceae) in Brazil

Abstract

The tribe Hippomaneae (Euphorbiaceae) in Brazil. The tribe Hippomaneae is discussed with respect to its taxonomic history, its placement within the Euphorbiaceae, its diagnostic characters (particularly the floral buds), current data on phylogeny and subdivision, and its general pattern of diversity. The tribe is represented in Brazil with 13 genera and ca. 120 species. A key to the Brazilian genera is provided. All Brazilian genera are discussed, citing relevant characters, recent taxonomic literature, and the current state of knowledge, sometimes pointing to unresolved problems. For five of the genera, published revisions exist; six genera have unpublished but completed revisions or are currently under revision. Actinostemon and Gymnanthes are currently the most difficult genera, mostly based on the absence of available up-to-date taxonomic references. For Mabea and Senefeldera, two genera with completed but currently unpublished revisions, additional data are given on aspects of their taxonomy, ecology and biogeography.

Systematic wood anatomy of the tribes Euphorbieae and Hippomanieae (Euphorbiodeae, Euphorbiaceae) from India

“…Present study supports the segregation of the genera viz. Balakata, Shirakoipsis, Triadica and Falconeria from the genus Sapium by Esser (1999Esser ( , 2002 and Kruijt (1996).…”

“…Further morphological phylogeny of Hippomaneae by Kruijt (1996) and Esser (2001) supporting the, rearrangement of the previously unnatural Sapium into several distinct genera and proposed a new overall generic classification of the Hippomaneae based on a worldwide morphological survey of members of all genera and sections of the tribe. A number of species recently been excluded from Sapium by Kruijt (1996) and Esser (1999Esser ( , 2002, so that the actual number of currently accepted species is around 20 only (Esser 2012).…”

Short Communication: Note on Excoecaria indica (Willd.) Muell.-Arg, 1863 (Euphorbiaceae), from the Andaman and Nicobar Islands, India; a data deficient species

“…The distribution and habitat ecology of E. indica is poorly known. Generally it is known to occur in primary Nypa forest in sea water, tidal river banks and sea shores (Giesen et al 2006) and in primary and advanced secondary forests of swampy and seasonally inundated places (Esser 1999 Singapore, 160 pp (1999). (Figure 2) Tree up to 10-15m high, columnar or spreading, mutlistemmed, dioecious, deciduous; bark grey, rough, fissured on maturity, pustular with lenticels.…”

Stillingia: A newly recorded genus of Euphorbiaceae from China

“…Nevertheless, newly described or newly recorded plant genera are not discovered and reported very often, suggesting that botanical expedition and plant survey at the generic level may be advanced in China. As far as we know, only six and eight angiosperm genera respectively have been newly described or newly recorded from China within the last ten years (Qiang et al 2007, Liu et al 2008, 2012, Liu & Yang 2011, German et al 2012, Deng et al 2013, Zhai et al 2013, adding up to the number of angiosperm genera from China of 3,120.…”
