New and little known Malayan Plants. 



Series II. 



By H. N. Ridley. 



This is another contribution to the knowledge of plants of the 

 Malay Peninsula and adjacent countries, some species of which 

 have been collected by myself, others by Dr. Gimlette in 

 Kelantan, Mr. Rostado in Tringanu, Mr. Machado in Perak and 

 Mr. Burnmurdoch in the rich forest of Semangkok Pass in 

 Selangor. The most remarkable discovery is that of an indig- 

 enous species of Palmyra Palm, Borassus, by Mr. Machado in 

 the forests at Kamuning.
