394 Mr. J. Miers on some genera of the Icacinacese. 



features that cannot constitute any generic distinction. I have 

 therefore divided them into corresponding tribes. 



The following outline of its generic characters has been derived 

 from my own observations. 



Mappia, Jacq. Stemonurus, Wight, non Bl. Nothapodytes, Bl. 

 — Flores perfecti, interdum polygami. Calyx breviter cam- 

 panulatus, fere integer, denticulis 5 donatus, immutatus et 

 persistens. Petala 5, oblonga, carnosula, intus villosa, imo 

 disci inserta, sestivatione valvata, sub anthesi patentia. Sta- 

 mina 5 cum petalis inserta, iisdem alterna; filamenta basi 

 dilatata, carnosula, superne subulata, sestivatione induplicata ; 

 anthera introrsse, ovatse, 2-lobse, 4-locellatse, imo breviter 

 bifida?, connectivo tenui, dorso in sinu affixse, lobis singulatim 

 2-locellatis, demum septicidis, et longitudinaliter evolutim de- 

 hiscentibus. Pollen reticulatum, 4-sulcatum vel subquadra- 

 tum. Ovarium liberum, ovatum, interdum subgibbum, villo- 

 sum, imo glabrum, et disco cupuliformi libero margine lobato, 

 extus glabro, intus ssepissime hirsuto hinc circumdatum, 1- 

 loculare ; ovula 2, juxta apicem loculi subcollateraliter suspensa, 

 anatropa. Stylus teres, interdum brevis, erectus, rarius 

 paullulo curvatus. Stigma erectum 2— 5-lobum, cavum, demum 

 capitatum. Drupa oblonga, epicarpio parco carnosa, olivse- 

 formis, ianthina, monopyrena, calyce persistente suffulta : pu- 

 tamen osseum, tenue, extus irregulariter sulcato-rugosum, 

 crista apicali et laterali; semen suspensum, oblongum, testa 

 membranacea, raphe dorsali, ab apice versus basin tendens, 

 chalaza fere basali : embryo in axi albuminis carnosi immersus, 

 orthotropus, inversus, fere ejusdem longitudine, cotyledonibus 

 majusculis, foliaceis, ovati3, radicula 3-plo longioribus. — 

 Arbores in Asia tropica, et Antillis crescentes, folia lanceolata, 

 oblonga, aut ovata, acuminata, integra, subpubescentia, petiolata ; 

 inflorescentia paniculata, terminalis, flores parvuli, flavescentes, 

 odore fcetido, rarius suaveolente emittentes, cum pedicellis arti- 

 culati. 



§ 1 . Eumappia. Discus cupularis profunde et obtuse 5-lobatus, 

 lobis extus 2-costatis, utrinque glaberrimis. Species Antillance. 



1. Mappia racemosa, Jacq. Hort. Schoenb. i. 22. tab. 47. Ica- 

 cina dubia, McFad, Fl. Jam. i. 122 ; — foliis lanceolatis, utrin- 

 que acutis, glaberrimis, nitidis, penninerviis, nervorum axillis 

 glandula supra verrucseformi subtus cava signatis, petiolo 

 longiusculo, glabro, canaliculato ; paniculis axillaribus, folio 

 brevioribus, plurifloris, floribus parvis, flavescentibus, odore 

 foetido, calyce glabro, denticulate, petalis extus lsevibus, intus 

 sericeis. — Jamaica; v.s. in herb. Hooker (MacFadyen).
