20. Stemonurus Ceylaniciis, n. sp. ; — ramulis glabris, ochraceis ; 
foliis oblongis, utriuque virentibus, subtus pallidis, costa 
inediana prominenti ; paniculis axillaidbus, geminis, dichotome 
ramosis, petiolo brevi 3-plo longioribus, pubescentibus, floribus 
in ramis secundis, crebris, calyce 5-denticulatOj glabro, petalis 
linearibus, sicco aurantiacis, staminibus iisdem sequilongis, 
apice carinaqiie interna longissime ciliolatis ; ovario sterib, 
glabro, depresso-lO-lobato, apice profun de 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 inflorescenee, in its much shorter and geminate panieles, 
in which the flowers, though somewhat secund, appear almost 
aggregated. The leaves, which ai-e 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, 
on a petiole barely exceeding 3 lines in length. The panicles 
are scarcely 9 lines long; the calyx is small, obsoletely 5-toothed ; 
thefive petals are linear, with a long inflected apex; thefive stamens 
are equal to them in length, with broad, thick, fleshy filaments, 
the internal keel, upper margins and summit being closely 
fringed with very long clavated hairs, which are three times the 
length of the anthers ; these consist of two oval lobes, fixed 
together by a point near the apex, where they are attached to 
the filaments, the lobes below being separated by the summit 
of the keel, so that they rest in two cavities in the apex of the 
filaments, as occurs in most species of this genus ; the ovarium 
is globular, somewhat 10-lobed, depressed at the summit, and 
deeply umbilicated in the centi’e, in the cavity of which, the ob- 
solete style and stigma, forming a depressed lobe, lie coneealed ; 
the body of the ovarium is fleshy, with no apparent cells*. 
21. Stemonurus Walkeri, n. sp. ; — ramulis teretibus, subdieho- 
tome divisis ; foliis oblongis, imo vix acutis, apice valde ob- 
tuso et bine subito attenuatis, utrinque glaberrimis fuscis et 
concoloribus, crasso-coriaceis, supra nitido-opacis, costa sul- 
catis, nervis immersis, subtus costa crassiuscula nervisque 
tenuissimis prominentibus, margine subrevoluto, petiolo bre- 
viusculo ; racemo axillari, brevi, paucifloro, floribus S 4-meris, 
$ 5-meris, filamentis crassis, apiee sub-breviter eiliolatis. — 
Ceylon. — v. s. in herb. Hook. ( S Col. Walker, ? Gardner, 101).
