BOTANICAL EXCURSION TO GUNONG JERAI. 29 



yellow flowers. It was described under the name of U. invol- 

 vens, Ridl. 



The ascent to the summit of the mountain is steep in parts 

 but there is a good track through the woods which clothe it to 

 the top. The view from the point is very fine and embraces an 

 extensive tract of country, while on the sea side the Lankawi 

 islands can plainly be seen. The height is estimated at a little 

 over 4000 feet; by my aneroid I calculated it to be, a little under, 

 viz., 3495 feet. The southern side is quite precipitous with near- 

 ly vertical walls of many hundred feet; at one spot not far from 

 the camp a stream runs over one of these precipices so steep 

 that standing on the edge one cannot see the fall of the stream 

 without bending over. Part of the rocky slopes on this side is 

 coated with turf upon which I was about to step when one of 

 the men restrained me and showed me that at a slight push the 

 whole mass slid off from the smooth rock and went down the 

 side of the precipice. On these rock-slopes grew a pretty Bcea 

 (B. eler/ansj the only one I have met with which did not grow on 

 limestone rocks, and with it was an Arundina with small flowers, 

 not unlike the Arundina Philippi of our gardens. The biggest 

 trees on the top were a species of Pieris, somewhat resembling an 

 Arbutus with long racemes of white bell-shaped flowers. A new 

 species of Uedychium (H. collimun) with white flowers was obtain- 

 ed, but only beginning to flower. A white-flowered Canscora was 

 common near the top. It was quite distinct from the one which 

 grows around the Kwala Lumpur Caves, and is the second species 

 obtained in the peninsula, none being recorded in the Flora of 

 British India. 



Orchids are far more numerous here than on Mount Ophir, 

 and in places form an important portion of vegetation. In 

 some spots the ground was so thickly covered by them that one 

 was nearly up to the waist in them and had to cut one's way 

 through the masses of tangled stems. Among the most striking 

 were Sjxfthoglottis aurea, Gypripedium barbatum, Dendrobiwn san- 

 gvinolentum and more commonly the pale ochre-colored form ceri- 

 nnni D. Hughii. with large thin white flowers tinted with violet, 

 and D. revolutum. Bulbophyllums were very abundant, among 

 them were B. longiftorum with large pink striped flowers with an 

 orange lip, and B. hispidum only met with at the very summit,
