222 APOCYNACExE. [Pottda. 



drical ; the limb spreading, with short, scarcely oblique lobes. Anthers pro- 

 jecting from the tube, sagittate ; the 2 basal lobes ending in long points. 

 Disk annular, deeply 5-lobed. Ovary of 2 distinct carpels, connected by a 

 single style, with an ovoid stigma. Ovules several in each carpel. — Climbers. 

 Leaves opposite. Flowers small, paniculate. 



A genus consisting of only one, or perhaps two, species from tropical Asia. 



1. P. cantoniensis, Hook, and Am. Bot. Beech. 198, t. 43. A slender 

 woody climber, glabrous, or the young branches sprinkled with a minute brown 

 pubescence. Leaves from cordate-ovate to oblong, obtusely acuminate, 2 to 

 3 in. long, on a slender petiole of ^ to 1 in. long, smooth and shining on the 

 upper side. Flowers small, pink, in a large loose terminal trichotomous pa- 

 nicle, each pedicel about 3 lines long. Calyx scarcely f line, and in the 

 Chinese as well as in the Indian specimens I always find about 20 glands. 

 Corolla-tube about 2 lines long ; the lobes little more than half as long, ovate 

 and scarcely oblique, although convolute in the bud. Disk-lobes lanceolate, 

 longer than the carpels. — P. ovata, A. DC. Prod. viii. 442. P. Hookeriana, 

 Wight, Ic. t. 1306. 



Hongkong, Champion, Wright. Also in Khasia, Silhet, Malacca, and Java. 



10. ECDYSANTHERA, Hook, and Arn. 



Calyx with 1 or 2 glands between each 2 lobes on the inside. Corolla 

 campanulate ; the lobes ovate, scarcely obtuse, about as long as the tube. 

 Stamens inserted in the tube ; the anthers scarcely protruding, sagittate, the 

 basal lobes short, sterile. Disk annular, entire or slightly crenate. Ovary of 

 2 distinct carpels, united by a short style with a conical stigma. Fruit of 2 

 diverging follicles. Seeds with a coma of long silky hairs. — Climbers. Leaves 

 opposite. Flowers small, numerous, in loose terminal or axillary panicles. 



A genus of very few species, all from tropical Asia. It scarcely differs from Pottsia, to 

 which at any rate ought probably to be referred the E. glandulifera, DC, as well on ac- 

 count of the calycine glands and the disk, as the shape of the corolla. 



Leaves glaucous underneath. Corolla 2 lines long 1. E. rosea. 



Leaves green underneath. Corolla scarcely above 1 line long . . . 2. E. rnicrantha. 



1. £3. rosea, Hook, and Arn. Bot. Beech, t. 42; A. DC. Prod. viii. 442. 

 A tall climber, with slender branches, glabrous, except a very slight glaucous 

 pubescence on the inflorescence. Leaves oval-oblong, shortly acuminate, \\ to 

 2 in. long or seldom more, narrowed into a petiole of 4 to 6 lines, somewhat 

 shining above, glaucous underneath. Flowers small, pink, very numerous, in 

 an elegant terminal panicle. Calyx not \ line long. Corolla about 2 lines 

 long, rather broadly campanulate ; the lobes broad, obtuse, rather shorter than 

 the tube, scarcely oblique but contorted in the bud, and from right to left (as 

 seen from the centre of the flower) in all the flowers I have examined of this 

 and the following species, not from left to right, as stated by De Candolle. 

 Disk annular, entire, shorter than the pubescent carpels. 



In ravines at West Point, Champion; woods of the Happy Valley, Wilford ; also Wright. 

 On the adjacent continent and in Java, and perhaps the Malayan Peninsula. 



2. E. rnicrantha, A. DC. Prod. viii. 442. A tall climber like the last, 

 but not so slender, perfectly glabrous except the inflorescence, which is slightly 

 pubescent, but without the glaucous mealy look of E. rosea. Leaves more
