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



stinctly separate, thin, membranaceous, white, flattened, boat- 

 shaped and valveless, fixed one on each side of the connective ; 

 they are longer both above and below, so that the anthers are 

 emarginated at the apex and base ; they generally open extrorsely 

 by the separation of the posterior margin of the cells from the 

 connective, or they sometimes, though rarely, separate by both 

 margins. The ovarium has been described as being glabrous, 

 but I have constantly found it clothed with long, erect, setaceous, 

 shining, white hairs ; the lower pai't is invested by a glabrous, 

 adnata, cupshaped disk : the style is erect and somewhat bent, 

 glabrous, rather subulate, slender, and of the length of the sta- 

 mens : there is no apparent stigma, but the apex of the style is 

 hollow and crowned with three very minute teeth : the ovarium 

 contains three radiate, excentric cells, each showing two ovules 

 suspended from near the apex. 



4. Emmotum affine, n. sp. Pogopetalum affine. Planch. MSS. ; — 

 foliis ovalibus e basi rotundato gradatim angustioribus apice 

 fossulato et deflexo longe attenuatis, subconvexis, supra niten- 

 tibus, costa sulcatis, nervis subprominulis, venis creberrime 

 transversis immersis, subtus ferrugineis, et glauco-pruinosis e 

 pilis brevissimis adpressis sub lente visuris, margine valde re- 

 flexo, petiolo subtenui sulcato rufo-glaucescente ; racemis axil- 

 laribus, floribus aggregatis cano-pilosis, petalis intus in cari- 

 nam pilis longissimis rufis dense lanatis lateribus glabris : sta- 

 minibus spec, prseced. : ovario piloso, disco glabro insito. —

This species comes very near E. acuminatum ; the leaves are 

 very shining above as in that species, and ferruginous beneath, 

 but the hairs that clothe its under surface are so minute as to be 

 seen only under a strong lens ; they are somewhat convex above 

 and the margins are very revolute, the attenuated apex being 

 deeply channelled and curved downwards ; they are about 4^ , 

 inches long and 2 inches wide, with a somewhat slender and 

 almost terete petiole, which is often suddenly deflexed. The in- 

 florescence is axillary in a few of the upper leaves, but is mostly 

 terminal in branching alternate racemes, each about three- 

 quarters of an inch long. 



5. Emmotum nitens. Pogopetalum nitens, Benth. he. citat. ; — 

 ramis striatis ; foliis oblongis, acuminatis, coriaceis, supra gla- 

 berrimis, pallide glaucis, sub-nitentibus, subconvexis, nervis 

 subprominulis, venis transversis immersis, subtus pube sericea 

 adpressa densa incana aut fulva vestitis, nervis valde promi- 



; nentibus, margine reflexo, petiolo elongato cano-tomentoso
