For this very ornamental species we are also indebted to T. Evans, esq., whose collector discovered it 

 growing about the sides and clefts of rocks near a waterfaliin the interior of the Island of Pulo-Pinang 

 in 1808. As yet it has only produced male flowers at Stepney ; but the bulbs in the axils of the leaves 

 always supply abundant means of propagating it, and its beauty and liveliness of colouring well entitle 

 it to a place in every curious collection. 



The drawing was taken at Stepney, last October, from a plant about two feet four inches in height.
