DIAGNOSES OF HAINAN PLANTS, II 



By Elmer D. Merrill 

 Director and Botanist, Bureau of Science, Manila 



In the first paper of this series, published in 1922, * thirty- 

 seven presumably new species were described. The present 

 paper contains the descriptions of fifty-two additional forms 

 which, like those in the first paper, are for the most part based 

 on collections made by Mr. F. A. McClure, of the Canton Chris- 

 tian College. Mr. McClure's first trip to Hainan was made in 

 September to December, 1921, and his second one in March to 

 May, 1922. Most of the species described in the present paper 

 were collected on the second trip. 



Mr. McClure 2 has given a very interesting account of his 

 work in Hainan, to which the reader is referred for details 

 regarding the country and its vegetation. On both trips col- 

 lections were made on Ng Chi Leng (Five Finger Mountain). 

 This is the highest peak in Hainan, having an altitude of about 

 1,900 meters. The first attempt, in December, 1921, to reach 

 the summit failed, but the goal was attained on April 30, 1922; 

 Mr. McClure's party was the first to reach the top. 



In connection with the work of identifying Mr. McClure's 

 botanical collections, I have prepared a manuscript enumeration 

 of Hainan plants. Previous to Mr. McClure's explorations in 

 Hainan, but about three hundred seventy species had been defi- 

 nitely recorded from the island in botanical literature. His
