Introduced by us from New Granada about the same time as 

 Z}jgo]:)etahmi Dayanum, to which it is closely allied. It was one of 

 the discoveries of Gustav Wallis while collecting for us in that rich 

 orchid region^ but who never divulged the localities in which they 

 were made. It seems to have long since disappeared from 

 cultivation.

Leaves distichous, the lower ones reduced to foliaceous scales, the 

 upper ones linear-ligulate, acute, upwards of a foot long. Peduncles 

 about one-third as long as the leaves, one-fiowered ; bracts lanceolate, 

 acute, pale brown. Flowers fleshy, 2| — 3 inches in diameter; sepals 

 and petals plum-purple with symmetrical longitudinal white stripes, white 

 at the very base ; the sepals elliptic-oblong, with a yellowish green 

 apiculus ; the petals broader, obovate-oblong, obtuse ; lip oval-oblong, 

 emarginate, with two small erect, triangular, basal auricles that are 

 vinous purple ; the blade densely studded with bristle-like papillae 

 arranged in close-set lines ; crest large, semi-circular, ridged and furrowed, 

 chestnut-brown. Column triquetral, slightly curved, vinous purple.

Discovered by and named after Mr. F. C. Lehmann, the German 

 Consul in New Granada^ who sent it to M. Ortgies, of the Botanic 

 Garden at Zurich. No locality is recorded, but it is said to occur 

 at an altitude of 3,500 — 4,500 feet, where the temperature is very 

 equable— 17°— 19° C. (64°— 67° F.) average mean— and the humidity 

 very copious throughout the year. It is without doubt a beautiful 

 orchid, but like many of its congeners it is a difficult plant to 

 import alive, and it has thus far baffled the efforts of cultivators 

 to grow it successfully.
