3. Cyathostemma, Griffith. 

 Scandent shrabs. Flowers subglobose in di- or tri-chotomous pendu- 

 lous cymes from the old wood (flowers dimorphous in sp. 3.) Sepals 3, 

 connate, hirsute. Petals 6, 2-sei'iate, short, sub-equal, their bases fleshy, 

 all valvate at the base, the tips imbricate. Torus flat, margin convex. 

 Stamens many, linear ; anthers sub-introrse ; process of connective ob- 

 lique, incurved. Ovaries many; style cylindric, glabrous, notched ; ovules 

 many. Ripe carpels oblong-ovoid, many-seeded. 



The petals in this genus are so unmistakeably imbricate in estiva- 

 tion, that I remove it from the tribe Unonece to TJvariai. The ripe carpels 

 moreover much resemble those of some species of JJvaria. Of the five 

 species described below, three are quite new. The first (0. viridiflorum) 

 is the plant upon which Griffith founded the genus ; while the fourth has 

 been hitherto referred to JJvaria under the specific name U. parviflora. 

 Flowers uniform and hermaphrodite. 



Flowers in more or less elongated pendent 

 cymes 

 Leaves oblong-lanceolate or oblanceolate ; 



inner petals contracted at the base ... 1. C. viridiflorum. 

 Leaves obovate-elliptic to obovate-oblong ; 



petals not contracted at the base ... 2. G. Scortechinii. 

 Flowers in stem-fascicles of 10 to 14, or in 

 axillary pairs ; leaves with pubescent 

 midribs ... ... ... 3. G. Wraiji. 



Flowers in 2- or 3-flowered extra-axillary 

 or leaf- opposed fascicles or cymes : 

 leaves quite glabrous ... ... 4. C. Hooheri. 



Flowers dimorphous, the females with a few abor- 

 tive anthers ... ... ... 5. (7. acuminatum. 



1. Cyatiiostemma viridiflorum, Griff. Notulse TV, 707: Ic. PI. 

 IV, t. 650. Scandent (?) the young branches thin, glabrous, dark-col- 

 oured when di'y. Leaces coriaceous, oblong-lanceolate or oblanceolate, 

 apiculate ; the base slightly narrowed, minutely cordate : both sur- 

 faces rather dull ; the upper glabrous except the minutely tomentose 

 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 To to 2 in., petiole '2 in. Cymes dJchotomous, on peduncles 

 several inches long from warty tubercles 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
