This gonns is dedicated to the memory of Adolph DiermaEu, at one time Curator of the Botanic
Garden, Calcutta. Tho oaly spedes at present belonging to it BI e B. Khaaidhn, • publ ished by us in the
Jourii. As. Soo., Bengal, for 1897, and the present plant wliioh was originally published by us in tho
same Journal (Vol. LXIV, pt. 2, 340) under the name Sarcochilus himactilnlvs.. But as the genus
Sarcochilus in the ptssent work is defined exactly as we believe its author deshed that it should
be, this plant cannot be included in it; and, as its chai'acters agree with those of no other genus, we
h a r e been obliged to form one for it reception.
