 the lower (or hypochiliniii) i» unguiculate, and extended in from into a long greenish yellow spur, 

 which curves upward* and is closed by numerous white hairs, while its margin, of a dull purple, is 

 curved inwards: the upper (or epiehilitim) is broad, kidney-shaped, retuse. slightly unguiculate, with 

 nn intermediate point, dull purple, with a yellow border divided into fringe-like teeth, and an acute 

 longitudinal crest through its centre. The column is erect, thick, purplish, very short, tapering 

 upwards into a narrow space, and extended downwards into a short foot. The stigma is large, 

 oblique, and extended into a large projection from the upper edge of the anther-bed. Tho anther 

 is oblique, obtuse, not crested, and extended in front into a truncated plate which COVOrt over the 

 caudicula and gland. Pollen-masses two, round, hard, deeply twodobed at the back, attached to 

 a long broad enudiculn. — Note. The structure of this singular tlower is so very intricate that it is 

 unusually difficult to describe it correctly. The lateral sepals are united below the slightly extended 

 foot of the column, and together with the unguis of the hypoehiliuin form u very short spur : while 

 the more conspicuous horndike spur is really the apex of the same part* 



Dr. Wallich named the plant Okxitiiociiilus, or Bird-hill, in allusion to the appearance of the 

 column and anther, which together resemble very much a duck's head ; I have however combined it 

 with Aeridcs, for the present at least.

Tliii, the Inst subject in the wreath, was like all the other* found by Dr. Wallich, who mot with 

 it in May, 1818. growing upon the branches of trees nt Toka in Nepal, where auch epiphytes nre 

 culled SuaipiaHff, whence tile name Snnipia was taken by Dr. Buchanan Hamilton : all those how- 

 ever which were described from that traveller's papers by the late Sir James Smith in Rces's 

 Cyclopaedia, under the genus Stclis, appear to hove belonged to the genua Bolbophyllum. 



A very loiif- ami minute Latin description of living specimens of this plant, by Dr. Wallich, is 

 before me, of which 1 avail myself in pari: with such additions or corrections as the examination of 

 dried Bowers in my herbarium renders necessary. 



The shoots or nuizosiATA are as much as a foot long, and form un entangled mass held down to 

 the ground by numerous perpendicular roots, just us in our hardy 9 |iccics of Iris ; from these spring in 

 abundance small inversely pear-shaped PSBuDO-bolbs, which are about an inch long, and terminated
