To a distinct genus! The species was first described by the younger Reichenbach in 1886 from a specimen sent home from Malacca by F rstermann and cultivated by Messrs. Sanders. The original description states quite clearly the characters by which it differs from its closest allies, D. aduncum Wall. ex Lindl. and D. linguella Reichb. f., namely, the much less prominent mentum and the separation of the lip into two distinct portions, the lower larger and cup-shaped and the upper triangular, with a transverse fimbriate lamella separating them from one another. About the same time (1885) Mr. Ford, of the Hongkong Botanic Gardens, sent to Kew a Dendrobium which he said ' is cultivated about Canton." A drawing of this by Miss M. Smith was submitted to Reichenbach and he agreed that it was his D. hercoglossum; this drawing agrees perfectly with our plate. After this the species was widely spread in.
