THE GESNERAUEiE OF THE MALAY PENINSULA. 43 



(Wray 9 27 & 480) ; Dindings, Simpit near Lumut 

 (Ridley 3073) Larut Hills to the top (Curtis 2040 & 

 2992) (Ridley 2913) (Scortechini 20 & 257 a; a remark- 

 able rufous haired form. Goping (King's Coll. 1099). 



Distrib. Sumatra. 



The form from the top of the Larut HilJs has much nar- 

 rower more glabrous leaves but the plant is remarkably 

 variable in foliage. It forms often great masses in woods 

 and is quite common in the hilly districts. The type 

 form of the species is a rock plant confined to Penang, 

 but the commonest form is the variety monticola. Clarke's 

 D. prod acta was based on one of Horsfield's Sumatran 

 plants in the British Museum. This type seems to me 

 identical with some of the hill forms in the peninsula. 



Var. violascens. 



Stems ascending for a foot or so. Leaves rather 

 remote nearly glabrous above except the edges and midrib 

 densely hairy, more hairy beneath, nerves elevated densely 

 appressed hairy. Flowers purplish white. 



Selangor, Rawang (Ridley 7583), Dusun Tua (7584). 



22. D. Ophirensis. n.sp. 



Stem long creeping over a foot long. Leaves opposite 

 somewhat unequal elliptic dark green with white on the 

 nerves 1-3 inches long -J-l inch wide base rounded, above 

 sprinkled with short hairs, edges entire thickly hairy, 

 beneath paler more hairy, nerves 5-6 pairs densely hairy, 

 petiole \ inch long hairy. Peduncles subterminal 1 inch 

 long hairy. Sepals linear ^ inch long densely hairy. 

 Corolla | inch long gradually dilate forwards, rather 

 broad at the top, hairy purple and white, upper lip much 

 shorter than lower one. Stamens filiform little shorter 

 than the corolla. Style slender. Stigma capitate. Cap- 

 sule cylindric hairy 1 inch long. 



Malacca, lower part of Mount Ophir (Ridley 3185). 

 I took this at first to be D. marginata, Clarke, which was 

 based on a plant collected in Malacca or Luzon by Lobb,
