REFERENCE TO THE PLATE.

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 waterfall in 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.
