54 FLORULA HONGKONGENSIS. 
dunculi ad apices ramulorum brevium breves, 2—3-flori. Bractee 
parve, squameformes. Pedicelli 7-8 lin. longi. Calycis laciniæ 
oblonge, obtuse, 34 lin. longe. Corolla alba, glabra, tubo 5 lin. 
longo, crasso, basi subventricoso, intus notato, lineis pilosis 10 ad 
altitudinem gynostegii attingentibus, basi et apice alternatim con- 
niventibus ; lacinize 9-10 lin. longze, patentes, falcatze, hinc basi auri- 
culate. Gynostegium tubo corolle dimidio brevius. Corone sta- 
minec foliola 5, gynostegio adnata, antheris multo breviora, apice 
brevissime libera, simplicia, integra. Anthere terminate membrana 
elongata apice concava. Masse pollinis erecte, ellipsoideze, brevifixze. 
Stigma crassum, subpentagonum, obscure bilobum. 
à A single plant was found in April, 1849, climbing over the top of a 
small Oak-tree in the thick jungle of the Happy Valley. It had a 
beautiful appearance even at some distance. The waxy white flowers 
have in the daytime a slight and agreeable perfume, but at night the 
scent is delicious, resembling that of the Tuberose. The general habit 
and foliage are those of a Pergularia, or still more of Raphistemma, but 
the structure of the staminal apparatus is precisely that of Stephanotis, 
with which genus it also agrees in the size, form, and consistence of 
its flowers; perhaps’ however the whole genus Stephanotis might with 
more propriety be considered as a section of Pergularia.

var. Chinensis; foliis subcoriaceis nitidulis preeter costam glabris. 
Near the Hong-Kong magazine-guard.—Besides the want of all pu- 
bescence on the leaves except along the midrib, as observed by Hooker 
and Arnott (Bot. Beech. p. 200), and by Schauer (Pl. Meyen. p. 364), 
this form differs slightly from the Peninsular specimens in the consis- 
tence of the leaves, which are more leathery and smooth, with less pro- 
minent veins. The flowers are also not quite so small, the scales of 
the throat thicker and broader, with shorter decurrent lines of hairs, —— 
and the membranes at the top of the anthers are rather larger. But . ip 
these are probably all of them variable characters.
