Distrib. Endemic. 



A very distinct herbaceous species, widely separate from all other described 

 ©Id world forms by its habit and foliage. It has to some extent the facies of A. 

 (Scyphellandra) virgata, Thwaites (Enum. PL Zeyl, 21 ; Hook. fil. and 

 Thorns, in Hook. Flor. Brit. Ind. i. 189), but that is a more woody plant, and 

 is moreover distinguished by its stamens squamate on the back. 



It is not abundant on the island - r we only found it at one locality.
