A very distinct species. — The description is taken from a living spécimen 

 cultivated in the Buitenzorg Gardens, flowering January 1920. A non- 

 flowering plant collected in the same locality, nearly indistinguishable from 

 this when seen with the naked eye, differs in having the dimensions 

 somewhat larger, the fully developed leaves somewhat reddish beneath, 

 without hairs or ciliae, and the apex more distinctly acuminate, apiculate.
