Calyx-tube campanulate in flower, globose in fruit; limb 5-partite, 
segments more or less equal, all developed more or less into petiolate 
elliptical acuminate foliaceous, persistent lobes. Corolla tubular, some- 
what funnel-shaped, submembranous, puberulous outside, shaggy 
inside; throat bearded; limb 5-lobed ; lobes ovate-lanceolate, valvate 
in estivation. Stamens 5, inserted about the middle of the corolla-tube ; 
anthers linear-oblong, sessile. Disk hemispherical. Ovary 5-celled; 
style filiform, included, ‘with 2 linear little-dilated erect hirsute 
branches’? (Hook. f.); ovules very numerous, inserted on tumid 
placentas. Fruit subglobose, subtruncate at the apex, 5-celled ; dis- 
sepiments thin; seeds numerous.—A monotypic genus with opposite 
petiolate leaves, entire or cleft lanceolate interpetiolar stipules, and 
rather small flowers clustered in dense axillary not involucrate cymes. 
This genus as well as the previous one may perhaps be reducible to the Ceylon 
8enus Schizostigma, Arn. 
1. P. humilis, Hook. f. in Benth. et Hook. f. Gen. Pl. ii. p. 73. A 
nearly glabrous decumbent herb, about a foot long; stem somewhat 
wiry and compressed.. Leaves obovate, cuspidate, attenuate at the 
se, 3-6 by 14-23 in. ; petiole 4-4 in. ; lateral veins about 8-10 pairs ; 
stipules acute, about 4 in. long. Flowers about 4 in. long, shortly 
Pédicellate, many together in very shortly pedunculate axillary 
cymes, Lamina of the calyx-lobes not exceeding yy in. Corolla white.
