A singular little species, which flowered at Kew during 1890, and 

 again in October of the pre ent }ear. It is very distinct from every 

 other, though perhaps nearest >>'. ochthodes, Pfitzer. The flowers are 

 light greenish yellow except the upper half of the dorsal sepal, whieli is 

 suffused with light purple-brown. It is characterised by the very short 

 tails of the lateral sepals, scarcely half a line in length, in allusion to 

 which the name is given.

This belongs to the section SacrohibiuUr. and is the smallest- 

 flowered species of the group. It is readih distinguished from every 

 other by this character, the less open tube of the sepals, and the 

 nearly parallel or scarcely divarieate tails. It is perhaps nearest M. 

 trr,p!o(h f tt's,V.. Morr. The sepals are pale yellowish green, den^-iy 

 ~p..'iied with dark purple-brown, and somewhat suffused with a lighter 



yellowish white with a pair of larj: 



the lip has many light t 

 purplish lilies near the base. The sac of the lip is unusually small. 

 It flowered atCla-nevin in August 1891, and on subsequent occasions, 

 when it was sent for determination by Mr. F. \V. Moore, the Keeper of 

 the Royal Botanic Gardens.
