 colony. It has hard , thick tongue shaped leaves , lying flat upon the rhizoma , which 

 creeps upon the rock or iree it grows on; they have the texture of anAloe, and pro- 

 bably indicate, that the spec. does not inhabit damp shaded places , but rather such 

 not dry situations , as Mr. Cunningham assigns to Dendrobium aemulum and ijndula- 

 tum see Bot. Reg. 1699. obs. Flowers greenish while, wiih long slender sepals and

Caulibus pendulis, loliis ovato oblongis obtusis nervosis basi subcor- 

 datis, sepalis lanceolatis lateralibus parum productis, petalis oblongis 

 aculis, labello pubescente convoluto denticulato subunguiculato ovato, 

 callo baseos elevato transverso obsolete trilobo. 



Manilla. Cuming. Loddiges. — Flowers 9" circumf. and will probly be still larger, 

 when the plant becomes more healihy. The sepals and petals are a clear and brighi 

 rose - colour , the lip is downy and deeply stained with 2 large broad blood - red 

 blotches at its base. 



Huc: Lindl. Sert. 1840. N. 35: Flowers like those of nobile , purple all over , lea- 

 ves full 4" long by two in breadth ; stems pendulous. — At ihe base of the lip 

 there is a threelobed callosity, which lies across the channel, that leads from the 

 apex to the unguia. It is worthy of the especial considernlion ofBotanists, that this 

 callosity is absenl in D. coerulescens and nobile; we learn tliat the absenee or pre- 

 sence of such projection is not of generical importance. The hairy ridge , which 

 runs down the middle of ihe lip in many allied species is missing. — 12 fl. on one 

 stem. — Huc : Pescatorea t. 40.
