1. Emmotvm orhiculatum. Pogopetalum orbiculatum, Benth. 

 Linn. Trans, xviii. 685. tab. 43 ; — arbor 2-orgyalisj ramulis 

 cinereo- vel fulvo-tomentosis_, foliis ovato-orbiculatis^ apice bre- 

 vissime ac obtusissime acuminatis, coriaceis, nitidis, supra 

 lucidisj rachi tomentoso, nervis parallele incurvo-divaricatis, 

 venis creberrime transversis immersis, subtus cum petiolo 

 crasso profunde canaliculate incano- vel fulvo-tomentosis ; 

 ovario hispido, fructu globoso, calyce immutato suffulto. — In 

 Guiana Brasilia3 ad fluv. Padauri, confl. fiuv. Nigri. — Schom- 

 burgk. — [v. s. in herb. Mus. Brit, et Hook, fructu immaturo^ Rio 

 Preto, Prov. Pernambuco. — Gardner, n. 2941.) 



This species is remarkable for the shape of its leaves, which 

 are almost orbicular at the base and summit, are 2f to 3J inches 

 long, 2~ inches broad, on a deeply grooved petiole 6 or 7 lines 

 in length ; they are thick and coriaceous, very polished above, 

 with a finely shagreened surface, and densely covered beneath 

 with short yellowish tomentum : the simple racemes with a few 

 immature drupes are about f inch long. 



2. Emmotum acuminatum. Pogopetalum acuminatum, Benth. 

 he. supr. cit. 685 ; — arbor 5-orgyalis, foliis ovatis oblongisve, 

 apice longissime et anguste attenuatis, mucronulatis, coriaceis, 

 fusco -rufulis, supra lucidis et glaberrimis, in costam sulcatis, 

 nervis paucioribus vix prominulis, venis transversis immersis, 

 subtus pallide ferrugineis, glandulis minutis creberrime punc- 

 tatis, pube rara instructis, petioloque sulcato leviter pubescen- 

 tibus, demum glabris; racemis geminis, fioribus aggregatis 

 griseo-pilosis, petalis ovali-oblongis, intus in carinam pilis 

 longis rufis lanatis, marginibus utrinque glabris ; ovario pilis 

 destitutis et e glandulis minutissimis asperis glauco-pruinoso, 

 disco glabro insito ; stylo excentrico elongato, stigmate obso- 

 lete 3-dentato. — Rio Negro, Brasilise (Schomb. 970). 



The branchlets are somewhat compressed and angularly 

 striated : it is however distinguished from the other species by 

 the long attenuated summit of the leaves, which are also of a 

 remarkably dark copper or reddish colour when dried ; they are 

 about 4 or 4| inches long, including the suddenly narrow apex 

 of half an inch in length ; they are If to 2|^ inches broad, on a 

 petiole 5 lines long ; the nervures, about seven pairs, are parallel, 

 very divergent, curving, with finely reticulated transverse veins ; 

 the upper surface is polished and finely shagreened ; beneath they 

 are of a ferruginous hue, dead, almost glabrous, and when 

 viewed under the lens seem covered with minute raised glandular 

 dots : generally two racemes spring out of each axil, from g^ to f
