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



racemes^ f ^o f ^^^^ long, have numerous crowded flowers which 

 do not exceed 3 lines in length : the hairs of the filaments are 

 three or four times the length of the anthers, and arch over 

 them in a very graceful manner : the pollen-grains are acutely 

 3-gonous. 



19. Stemonurus CumingianuSj n. sp. ; — ramulis flexuosis, tereti- 

 bus, ferrugineo vel flavido-tomentosis ; foliis oblongis, utrin- 

 que acutis, apice repente attenuatis, supra glabris, subtus 

 brunneis et sparse pubescentibus, costa nervis petioloque 

 ferrugineo-pilosulis, margine subrevoluto; panicula ramosa, 

 petiolo tenui vix longiore, pubescente, floribus S crebris, sub- 

 capitatis, 5-meris; calyce brevissimo, 5-denticulato, piloso, 

 petalis glabris, oblongis, summo marginibus apiculaque longa 

 propendenti inflexis ; staminibus iisdem brevioribus, latis, 

 crassis, pilis clavatis longissimis ciliolatis; ovario oblongo, 

 piloso, dentibus 5 coronato. — Insul. Philip. — v. s. in herb. 

 Hook, et Lindl. (Cuming, 796) . 



The leaves here are 5-6i inches long, and 2J-3 inches broad, 

 on a petiole 5-7 lines in length ; the panicle is trichotomously 

 branched, with crowded 5-merous flowers, which are still in bud; 

 the upper margins of the petals are deeply inflected, together 

 with their long apical points, which are all closely agglutinated 

 into a long process that hangs down in the centre of the anthers ; 

 the filaments are rather short and broad, fringed with extremely 

 long glandular hairs ; the ovarium, seated on a short glabrous 

 disc, is cylindrical, and altogether very pilose, growing smaller 

 and more conical towards the summit, where it is hollow and 

 5 -toothed. 



20. Stemonurus Cei/lanicus, n. sp. ; — ^ramulis glabris, ochraceis ; 

 foliis oblongis, utrinque virentibus, subtus pallidis, costa 

 mediana prominenti ; paniculis axillaribus, geminis, dichotome 

 ramosis, petiolo brevi 3-plo longioribus, pubescentibus, floribus 

 in ramis secundis, crebris, calyce 5-denticulato, glabro, petalis 

 linearibus, sicco aurantiacis, staminibus iisdem sequilongis, 

 apice carinaque interna longissime ciliolatis; ovario sterili, 

 glabro, depresso-10-lobato, apice profunde umbilicato, stylo 

 brevissimo in cavitatem incluso. — Ceylon. — v. s. in herb. Lindl. 

 et Honk. (Macrae, 428). 



This species differs from S. Penangianus in the axillary origin 

 of its inflorescence, in its much shorter and geminate panicles, 

 in which the flowers, though somewhat secund, appear almost 

 aggregated. The leaves, which are thin and almost membrana- 

 ceous in texture, appear when dried of a darkish green above, 

 and of a very pale green beneath, with prominent nervures and 

 veins ; they are about 6 inches long, and nearly 2 inches broad.
