222 APocYNACEiE. [Pottsia. 



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

 jepting' fi-om the tube, sagittate i the 3 basal lobes ending in^ long points. 

 Disk annulari deeply 5-lobed. Ovanr of 2 distinct carpels, connected by a 

 single style, with an ovoid stigma. Ovules several in each earpel.^^Climbers. 

 Leaves opposite. Blowers small, paniculate. 



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



I. P. cantonieQSis, Rook and Am. Bot. Beech. 198, t. 43. A slender 

 woody cKpiber, glabrous, or the ypuug brancKes sprinkled with a minute brown 

 pubescence. Leaves from cordate-oyate to oblong, obtusely acuminate, 3 to 

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

 upper side. Mowers small, pink, in a large loose terniinal trichotomous pa- 

 nicle, each pedicel about 3 lines Iqng. 0?ilyx scarcely f liiie, and in the 

 Chinese as well as in the Iridian specimens I always find about 30 glands. 

 CoroUa-tube about 3 lines long ; the lobes little more than half as long, ovate 

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

 longer than the carpels. — P. ova,ta, A. DO. Prod. vui. 443. 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 3 glands between each 3 lobes on the inside. Corolla 

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

 Stamens inseii;pd in tl^e tube ; the anthers scarcely protruding, sagittate, the 

 b^s^al lobes s,hQrt) sterile. Disk annulai, entire or slightly crenatp. Ovary of 

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

 ^ivejgjng folHcleg. Seeds witji a coma of long silky hairs. — Climbers. Leaves 

 pppft?ite, Hpvpers small, nuraerous, in loose terminal or axillary panicles. 



A genus of very fe^ spgpigs, all from tropical Asia. It scarcely differs from Pottsia, tq 

 which ai ?ny rate ought prohably to be rpferred the E. gtandUmra, DC, as well 0}i ac- 

 count of the calycine' glands and the disk, as the shapa pf the eovella. 



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



Leaves green underneath. CoroUa scarcely above 1 line long . . i. M. miorantha. 



1. E. rosea. Hook, and Arn. Bot. Beech, t. 43 j A. BG. Prod. viii. 443. 

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

 pubescence on the infloresoenee. Leaves oval-oblong, shortly acuminate, 1\ to 

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

 Shining above, glaucous underneath. Flowers gmall, pink, very numerous, in 

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

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

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

 sedli from the centre of the flower) in all the flowers 1 have ex,aniined of this 

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

 Disk annular, entire, shorter than the pubescent carpels. 



In r^vifte? ftt Vest Poiut, Qhan^pipn; woods of the Happy Valley, Wilford; also Wright. 

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



3. E. micrantha, 4. BO. Prod, viii. 443. 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
