made, to His Grace the Duke of Northumberland. It has 

 flowered likewise with J. D. Llewelyn, Esq. of Penllegar, 

 who received the living plants from Mr. Cuming, with the 

 memorandum, as Dr. Lindley assures us, that they were 

 dug out of a bog in Sumatra: — a strange habitat for a 

 plant of this kind ; but which has given rise to the specific 

 name. It was, however, many years ago, detected at Sin- 

 gapore by Mr. Finlayson ; and from his imperfect speci- 

 mens it was, firstly, referred by Dr. Lindley to Grammato- 

 phyllum; and, afterwards, when the structure of the flowers 

 was known from living specimens, it was deemed worthy to 

 constitute a new Genus. It is a tall growing, graceful 

 plant, with very delicate flowers. 



Descr. Roots consisting of stout, fleshy fibres. Stem 

 three and four feet high, terete, erect, below clothed with 

 long, sheathing, striated scales, there leafy, with a few dis- 

 tichous, oblong, fleshy or rather coriaceous, obtuse, faintly 

 striated leaves: — above naked again, in what may be called 

 the terminal peduncle, which is also beset with sheathing 

 scales. This peduncle bears two or three spikes, densely 

 clothed with short, sheathing, distichous, imbricated herba- 

 ceous, tooth-like scales. From each of these scales a flower 

 proceeds. Sepals and calyx white, oblong-acuminate, nearly 

 equal, spreading, concave. Lip parallel with the column, 

 oblong, canaliculate, three-lobed, the side lobes involute, 

 white externally, within streaked with purple, and having a 

 pulviuate, oblong disk : the intermediate lobe is rounded, 

 acute, yellow in the middle. Column elongated, semi- 

 terete, the margin sharp and winged. Anther sunk in the 

 apex of the column. Pollen-masses on a large, triangular 

 gland.
