The material which I have referred to the genus Chamseanthus 

 SchJtr., and for which I propose the name ChamceantkusWenzelii, 

 came to me mingled with other specimens which Mr. C. A. Wen- 

 zel gathered on the island of Leyte, at Dagami, sixty meters above 

 sea level, on March 8, 1913. This material agrees so well in its 

 generic characters with Chamseanthiis that I feel no uncertainty
