Capsulis fusiformis apteris. 



Moolmeyn. — This pjant is evidently very near D. moschatum. It however appears 

 to have smaller flowers with far narrower segments , and as far as can be ascertai- 

 ned from dried specimens , they are nearly colourless . except the lip, which is yellow,

Foliis acuminatis, racemis nutantibus pendulisque multifloris, elon- 

 galis, bracteis minutis ovatis obtusis , floribus sucarnosis, sepalis sub- 

 rotundis basi in cornu brevi connatis, petalis latioribus inlegerrimis, 

 labello cochleato cucullato obtuso villoso fimbriato. 



Differs from D. clavatum by obsolete bracts and much smailer flowers. Nearly allied 

 to fimbriatum. Like D. fimbriatura it bears its flowers in long nodding racemes ; their 

 colour is yellow, and they are stained on ihe inside with a purple blolch in the same 

 manner as those of the plant figured in the Bot. Mag. under the name of D. fimbria- 

 tum oculatum. But ihe (lowers are snialler. between fleshy and leathery in texture, mucli 

 blunter in the bud , in consequence of the greater roundnes of all the parts, and the 

 petals are entirely destitute of the fringes which accompany those of D. fimbriatum-

 Some times known under ihe erroneous name of Paxtoni , whieh is a twoflowered 

 species. — Wild specimens of the dark eyed : Mergui Griffitii. The whole coloured : 

 Ncpal. — From D. clavatum it is known by its long membranous biacts, by ils smaller 

 flowers , D. Gibsoni has never open flowers and no fringes on petals.
