glandular at the base (Maingay). Corolla-tube funnel-shaped, 3; in. long, limb 4 in. 
diam., lobes inflexed at the tip in bud. Anthers half-exserted, with a narrow lanceo- 
late gland on the back, 
DOUBTFUL SPECIES, 
V. assamica, Griff. Notul. iv. 77; this agrees fairly well with the character of V. 
Heynei, but I find no specimens of this species in Griffith’s herbarium from Assam. 
His habitat is woods at Bishenath. 
V.? anceps, Wall, Cat. 1622; A. DC. Prodr. viii. 400 (without description) ; from 
Tavoy. This is not a Vallaris, but is in too imperfect a state for determination. Kurz 
(Journ. As. Soc, 1877, ii, 254) says that it seems hardly referable to Apocynee, 
22. POTTSIA, Took. et Arn. 
An evergreen climber. Leaves opposite, nerves distant. Flowers in lax 
terminal and axillary panicled cymes. Calyx small, 5-partite, glandular within, 
Corolla salver-shaped, tube cylindric; throat constricted, naked ; lobes over- 
lapping to the right. Stamens at the top of the tube, filaments hairy ; anthers 
exserted, sagittate, conniving over and adhering to the stigma, cells with basal 
empty spurs, Dise deeply 5-fid, lobes lanceolate, much longer than the ovary. 
Carpels 2, distinct, villous, many-ovuled, included in the dise; style slender, 
thickened in the middle and top, stigma conical. Foilicles elongate, slender, 
beaded. Seeds linear, elongate, coma deciduous, albumen copious ; cotyledons 
linear, flat, radicle superior.— DISTRIB. Species 2 or 8, Eastern Asiatic and 
Malayan.

Branches slender, smooth, cylindrie; twigs puberulous. Leaves 3-4 by 14-2 in., 
elliptic-ovate or ovate, acuminate, base rounded or subcordate, nerves 4-6 pairs; 
petiole slender, 1-1} in. Cymes drooping, long-peduneled, very many-fld. ; branches

ovate. Sepals broadly ovate, obtuse. Corolla 4-4 in., glabrous, rose-coloured, tube 
broad obtusely angled, lobes short ovate.  Follicles 1 ft., flexuous, smooth, thinly 
coriaceous. Seeds 1 in., very slender, glabrous, coma as long.—Griffith in his generic 
character of Huthodon describes the throat of the corolla as without scales; in the 
specific he mentions 5 glands in the sinus of the lobes; these I do not find in his 
specimens, 
23. WRIGHTIA, Br.

Flowers red, white or yellow, in terminal or subaxillary sessile cymes. Calyx 
short, 5-partite, with glands or scales inside. Corolla salver-sha ed, tube 
cylindric, usually short, throat with 1-2 series of usually fimbriate scales; lobes 
overlapping to the left. Stamens at the top of the tube, filaments short dilated ; 
anthers exserted, sagittate, conniving around and adhering to the stigma, cells 
spurred at the base. Dise 0. Carpels 2, free or connate, many-ovuled ; style 
filiform, stigma ovoid with usually a toothed basal ring. Fodlicles linear, erect, 
connate or distinct. Seeds linear, compressed, tip narrowed naked, base with a.
