Root concatenately bulbous, bulbs subglobose; leaf soli 

 tary, hiemal, pKiited, arid; scape sheathed, many-flower- 

 ed; flowers at length pendulous; germ attenuated, cylin- 

 dric. 



3. hiemalii. Cymhidiiim hiemale. Leaf solitary, ovate, 

 siriate; lip irifid, obtuse, with tlie palate ridged, central 

 lobe rounded, crenulate. II a b. In shady woods amidst 

 recent veget.ble soil, from Canada to Carolina — Scape 

 about 12 inches high, clothed with 3 membranaceous 

 sheathes; flowers brownish, at first erect, afterwards 

 pendulous. Petals linear-oblong, connivent, distinct, all 

 nearly equal in size and form. Lip unguiculate, distinct 

 at the base, and about the length of the petals, dila- 

 ted towards the extremity, trifid, ridged along the cen- 

 tre, the middle lobe rounded, with the margin undulated 

 and crenulate. Column of an equal thickness and slightly 

 curved, shorter than the lip; lid of the anther membrana- 

 naceous, caducous; pollinia 4, lenticular and cereaceous, 

 laterally attacl>ed to the summit of the column, at length 

 deciduous. — This plant, much more nearly related to the 

 present genus than any other with which I am acquainted, 

 besrs also a partial resemblance to Cymbidivm of H. Brown, 

 without, however, possessing any natural affinity, and is 

 totally diflTerent in habit and geographical range.
