A stately species, of which a dried inflorescence and partly-coloured 
sketch have been sent to Kew by Mr. Richard Pfau, of Costa Rica. 
It is allied to the Brazilian Æ. cooperianum, Batem. Mr. Pfau de- 
ribes it as a truly superb plant, growing from four to six feet high, 
cannot give the dimensions.

A very distinct and interesting little Biss which flowered with 
Mr. James O'Brien of Harr -the-Hill, in September 1890, and 
with M. A. Van Imschoot, of Gand, four years later, from both of 
whom materials were received for determination. It is quite. naika any 
other known species in its softly villose inflorescence, which is of a ote 
whitish green, like that of some species of is 
ite with minute purple spots on the disc, and a light yellow li as on 
tbe basal half.

An interesting addition to this singular little genus, of which living 
plants and dried specimens, together with a Metis sketch, have been 
sent to Kew by Mr. Richard Pfau, of Costa Rica. The flowers are 
white, with some purple markings on the middle and base of the lip. 
scapes are technically — as one-flowered in this group, though 
n the present species they are n in reality. The flowering axis is 
vie short, and Dacial in ie: axis of the leaf, whence ev one- 
flowered peduncles are pushed up, probably in successi he 
character may extend to other species, both of this and allied genera 
with a similar habit.
