The petals in this genus are so unmiatakeably imbricate in aestiva- 

 tion, that I remove it from the tribe TJnonece to Uvarice. The ripe carpels 

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

 species described below, three are quite new. The first ((7. viridifloruni) 

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

 been hitherto referred to Uvaria under the specific name TJ. parviflora. 

 Flowers uniform and hermaphrodite. 



Flowei's in more or less elongated pendent 

 cymes 

 Leaves oblong-lanceolate or oblanceolate ; 



inner petals contracted at the base ... 1, G. viridijlorum. 

 Leaves obovate-elliptic to obovate-oblong ; 



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

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

 axillary pairs ; leaves with pubescent 

 midribs ... ... ... 3. G. Wrayi. 



Flowers in 2- or 3-flowered extra-axillaiy 

 or leaf-opposed fascicles or cymes : 

 leaves quite glabrous ... ... 4. 0. HooTceri. 



Flowers dimorphous, the females with a few abor 



tive anthers ... ... ... 5. G. acuminatum. 



1. Ctathostemma viridiflorum. Griff. Notulge IV, 707: Ic. PI. 

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

 oured when dry. Leaves 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 1'5 to 2 in., petiole "2 in. Gymes dichotomous, on peduncles 

 sevei-al 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. Floivers "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. Bipe 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. Accordino- 

 to Griffith, the wood of this species resembles that of a Menisperm.
