(1) P. Wrayi Clarke, l.c. 668.

base acute, 5 in. long, 2 in. wide ; petioles 75 to 1 in. long. Racemes 
terminal, one or two on a terminal panicle, 2 to 4 in. long. Bracts

angular, acute in fruit, lengthening to *5 in. long. Corolla 1 in. 
long, pale primrose. Capsule more than 1 in. long, oblong-ellipsoid, 
smooth, retinacula large. Hob. Mountains at 6700 ft. altitude. 
Rare. Perak, Gunong Batu Putih (Wray). 
(2) P. major Clarke , l.c . 669. 
Shrub 6 to 8 ft. tall. Leaves equal, elliptic-lanceolate, acumin¬ 
ate, base shortly narrowed, 8 in. long, 3 in. wide or less; petioles 
1*25 in. long. Panicles 2 to 5 in. long, terminal or reduced to simple 
racemes. Flowers opposite in rather distant pairs; pedicels very 
short. Calyx *35 in. long, divided into narrow lanceolate teeth 
half-way. Corolla 1-25 in. long, waxy yellowish white. Hab. 
Perak, Gunong Batu Putih (Kunstler). Rare. 
(3) P. minor Clarke, lx. 669. . 
Shrubby glabrous. Leaves membranous lanceolate or elliptic- 
lanceolate, long-acuminate, base cuneate, often slightly inequi¬ 
lateral, edge obscurely undulate; nerves curved, about 8 pairs, 
6 in. long, 175 in. wide; petioles *5 in. long. Racemes terminal 
and in upper axils 2 in. long. Flowers about 15, in pairs. Bracts 
very short linear acuminate. Pedicels *2 in. long, ^epals 5, 
narrow lanceolate free nearly to base, *15 in. long. Corolla 75 in. 
long, tube trumpet-shaped; lips unequal, lobes short blunt, lower 
lip hairy on disc. Stamens 4 with short points below; anther- 
cells parallel. Ovary glabrous; ovules 4. Hab. Mountains. 
Perak (Scortechini) ; Gunong Inas (Yapp) at 37 °° altitude. 
The species was described from very poor material collected by Scortechini, 
and the description by Clarke is consequently somewhat inadequate. Unlike 
the other species, the calyx has hardly any tube, the sepals are free nearly 
to the base.

sub-entire, lower lip 3-lobed, all white, lower lip yellow, mouth 
inside hairy. Stamens 4, sub-similar; anther-cells muticous, one

clubbed with 4 warty seeds. Species about 10, Malay Peninsula 
and islands.
