58 A SCIENTIFIC-EXPEDITION TO TEMENGOH. 
Johor, Tana Runto; Malacca at Batang Malacca 
(Derry 257), Ayer Panas (Derry 84); Pahang, Tahan 
river (2227) and Penang Hill 7092 of my collections. 
This plant has comparatively small flowers, the 
tube slender, the lobes short, often subacute, the leaves 
broad, but as we go up the rocky streams of the higher 
lands we find a plant which differs in its habit, size of 
flowers, and the form of its leaves which may be ealled 
var montana. 
This is a straggling shrub with narrow lanceolate 
leaves gradually acuminate for a long way, 6 inches 
long and one inch wide, the corolla tube is 2 inches long, 
the limb 75 inch across. The typical low-country 
form has elliptic acuminate to lanceolate leaves and a 
corolla tube only an inch long and the limb ¢ inch across. 
The difference is so great that at first sight one would 
hardly identify them as the same species, but there are 
certainly intermediate stages and I cannot separate them 
definitely.

The form here has much narrower and longer leaves
