The petals in this genua are bo unmistakeably imbricate in Aestiva- 
tion, that I remove it from the tribe Unonem to Tfvarice. The ripe carpels 
moreover mnch resemble those of some species of Tfvaria. Of the five 
species described below, three are quite new. The first (0. viridifiorttvi) 
is the plant upon which Griffith founded the genus ; while the fourth has 
been hitherto referred to Uvaria under the specific name U. parviftora. 
Flowers uniform and hermaphrodite. 
Flowers in more or less elongated pendent 
cymes 
Leaves oblong- lan ceo late or oblanceolate ; 
inner petals contracted at the base ... 1. C viridiflorum. 
Leaves obovate-elliptic to obovate-oblong ; 
petals not contracted at the base ... 2. O. Scortechinii. 
Flowers in stem- fascicles of 10 to 14, or in 
axillary pairs ; leaves with pubescent 
midribs ... ... ... 3. 0. Wrayi. 
Flowers in 2- or 3-flowered extra-axillary 
or leaf-opposed fascicles or cymes : 
leaves quite glabrous ... ... 4. 0. Hooheri. 
Flowers dimorphous, the females with a few abor 
tive anthers ... ... ■■• 5- C. acuminatum. 
I, Cyathgstemma viridiploritm, Griff. Notulte IV, 707: Ic. PI. 
IV, t. 650. Scandent (?) the young branches thin, glabrous, dark-col- 
oured when dry. Leaves coriaceous, oblong- lanceolate or oblanceoljito, 
apiculate; the base slightly narrowed, minutely cordate: both sur- 
faces rather dull ; the upper glabrous except the minutely tomeutose 
midrib ; the lower darker, puberulous on the midrib and 8 to 10 pairs 
of rather prominent spreading main nerves ; length 4*5 to 7*5 in,, 
breadth 1'5 to 2 in., petiole *2 in. Cymes dichotoraous, on peduncles 
Beveral iuehes long from warty tnbercles on the older roughly striate 
branches, few-flowered, corymbose, minutely rusty- tomentose, with an 
oblong bract at each bifurcation and another about the middle of each 
pedicel. Flowers 5 in. in diam. Sepals broadly cordate, spreading or 
sub-reflexed. Petals acute, the base contracted especially in those of 
the inner row, coriaceous, tomentose. Ovaries tomentose. Ripe carpels 
stalked, 1 to 1"5 in. long, oblong-ovoid, blunt, glabrous ; stalk '75 in. 
Hook. fil. Fl. Br. Ind. I, 57 ; Kurz For. Fl. Burm. I, 33. 
Eastern Peninsula; Griffith. Penang ; Maingay (Kew Distrib.) 
No. 36. 
A species known by only a few imperfect specimens. According 
to Griffith, the wood of this species resembles that of a Menisperm.
