Sepala patentia, pelaloidea; lateralibus basi ima levissime producla 

 connatis. Pelala subaequalia, basi subobliqua. Labellum unguiculatum, 

 sepaiis longius, petaloideum ; hypochilio (ungue) lineari, apice saccato, 

 margine lobato ; mesochilio brevi e facie sacci, 3-corni; epichilio trans-

Allied to Huntleya, Warrea etc, but clearly distingnished by iis lonj» narrow hy- 

 pochil, with a deep bag at ibe point, surrounded by a flve-lobed reflexed bnrder. and 

 furnished in front wiih tiiree projecting processes arising from the very base of the 

 mesochil at its junction witb ihe hypochil and just above ihe concave ribbed base of 

 epichil. Mr. H. G. Keicbenbach's Paradisanlhus, with which I am unacquainled, 

 would seem to be also a genus relaled 10 this 



1. ACACALLIS CYANRA Lindl. I. c: 



Sepala et petala subrolunda, apiculala, basi cuneata. Hypochih'i saccus 

 margine acute 5-denlato auctus; mesochilii processus recti , subulati;

 late cuneatum, concavum, lobo medio minuto acuminalo integerrimo, 

 Columnae alae membranaceae; quadratae. Clinandrium dorso cornutum.

Tbis is a very flne plant, with the habit of a Maxillaria of the racemose seclion , 

 and wiih flowers as largc as ihose of Odonloglossum Pescnlorei. Mr. Spruce reporls 

 ihe sepals and petals 10 be light blue, paler within; the lip light bluish purple with 

 pale vcins ; back and wings of column streaked wilh red. He adds, ihat ihe blue of 

 Ihe flower is almost perfeclly pure. The lcaves are tbree inches broad by flfieen 

 inches long, wiih much the textuio of a Stanhopea; at ihc basc tbey gradualiy laper 

 into a furrowed petiole ihree inches long. Thc pseudobulb is ovalc , arfd onc-Ieaved. 

 The peduncle, including the close flve-flowered raceme, is about a foot long.
