Flora of the Malayan Peninsula. 693 



lar ; stopples 4 in the typical species, possibly 4 to 3 in other species. 

 Capsule stalked, with 4 seeds. — Disteib. Species: the 3 here described 

 and 1 in the Philippines. 



A group of species resembling in habit some of the Malay plants referred to 

 Ptysiglottis by Hallier f. in Nova Acta Leop. Carol. Akad. 70 (1897) (as P. lan- 

 ceolata, Hallier f. I.e. 221, t. 15, fig. 1, or P. frutescenn, Hallier f. I.e. 222, t. 16, 

 fig. 2), which have ellipsoid pollen longitudinally banded and anther-cells approxi- 

 mated. The type Ptysiglottis from Ceylon is remote in habit and has approximated 

 anther-cells. 



Leaves of opposite pairs (many of them) very unequal : — 



Leaves entire ; sepals -35 in. long .. .. ..1. P. vulgar e. 



Leaves finely crenulate ; sepals -2 in. long .. ..2. P. crenulatum. 



Leaves of opposite pairs equal or very nearly so . . . . 3. P. iao'pliyUam. 



1. PoLYTREMA vuLGARE, G. B. Clarke, n. sp. Nearly glabrous ; 

 branches round, somewhat zigzag. Leaves opposite, one reduced to 

 an ovate auricle '25 to "5 in. long, the other elliptic or broadly elliptic, 

 4 to 6 in. long, entire, covered with small rhaphides ; tip acuminate ; 

 base rhomboid not rounded ; primary nerves 10 to 11 pair ; petiole to 

 •175 in. long. Cymes few-flowered, small, sessile or very nearly so in 

 the axils ; bracts and prophylla hardly any. Sepals -35 in. long, seta- 

 ceous, minutely pubescent or nearly glabrous. Corolla -7 in. long ; tube 

 inflated in the upper half. Stamens 2 ; anther-cells 2, muticous, 

 distant, one rather the lower. Style glabrous. Capsule -7 in. long, 

 glabrate, with 4 seeds in the upper part.

2. Polytrema crenulatum, G. B. Glarke, n. sp. Branches 6 to 8 in. 

 long, decumbent, much divided. Leaves up to 2-5 by 1 in., subsessile, 

 elliptic-acuminate; margin finely crenulate. Cymes closely axillary, 

 1- to 3-flowered. Sepals -2 in. long, linear-setaceous, nearly glabrous. 

 Corolla '35 in. long. Otherwise as P. vulgare. 



Perak: Scortechini (two collections without number). 



This is possibly only a starved form of P. vulgare, but it is considerably smaller 

 in every part. 



3. Polytrema isophyllum, G. B. Glarke, n. sp. Herb, 1 to 2 ft. 

 high, nearly glabrous. Leaves opposite, equal, yellow when dry ; blade 

 4-5 by 1-75 in., elliptic-acuminate ; base cuneate, entire, covered with 

 rhaphides ; primary nerves 7 to 8 pair ; petioles '5 to 1 in. long. 

 Cymes small, few-flowered, closely axillary. Sepals -35 in. long, seta- 

 ceous, minutely pubescent. Corolla white, more than -Swin. long. 

 Stamens 2 ; filaments glabrous ; anther-cells rather long, not tailed.
