Descr. Tuber nearly as large as the fruit of a Horse-chestnut, 

 subglobose, rooting at the summit. Plant one to one and a 

 half feet high. Stem erect, simple, sheathed in the lower half, 

 and, as well as the sheaths, spotted. Leaves generally two, 

 long, petiolate, q innate; leaflets or folioles four to five inches 

 long, radiating, elliptical-lanceolate, suddenly and submucronato- 

 acuminate, the bases gradually attenuated into short petiolules, 

 quite simple (never pedate), penniveined ; veins simple, erecto- 

 patent. Spatha three to three and a half inches long, of a uni- 

 form pale-green, streaked with slightly darker shades of the 

 same colour : the lower half a little swollen at the base, convo- 

 lute into a cylindrical tube, equal in length with the floriferous 

 portion of the spadix, which it encloses ; upper half, or lamina, 

 nearly erect, ovato-lanceolate, concave, the superior portion of it 

 much acuminate and more or less incurved over the mouth of 

 the tube. Spadix throughout pale yellow-green, contracted im- 

 mediately below the appendage, and there only floriferous ; the 

 flowers singularly scattered, yet pretty regularly distant from 

 each other ; the lower one-third is occupied by pistils, the rest 

 by stamens ; no abortive flowers. Filaments stout, each bearing 

 two one-celled subglobose anther-cells, with a transverse fissure. 

 Pistil ovate ; stigma sessile, discoid. Appendage from a thick- 

 ened subglobose base, subulate, six inches long, gradually taper- 

 ing to an obtuse point, incurved in the lower portion, the rest 

 erect.
