These two species are recorded because in the large suite of speci- 

 mens collected, some examples agree exactly with Andamans specimens 

 named E. album by Dr. T. Anderson, and others agree exactly with the 

 original specimens of Mr. Kurz's E. succifolium. But I do not think 

 that there are really two species present. The plants ai-e referred by 

 Anderson to E. album, but are considered by Clarke a white-flowered 

 fern of E. cinnabarinum, and are held by Kurz to be two distinct species. 

 The original specimens of Kurz's Eranthemum album, T. And. ? (314 of 

 Nicobars list) I cannot, however, distinguish from those of E. succifolium 

 (813 of that list). 



184. RuNGiA PARViFLORA Nees, vav. PECTiNATA Clarke. 

 Table Island ; in the light-house clearing.
