distinctive form and outline have thick hypogeous cotyledons, 

 and we have the characteristics of a genus naturally quite 



separate from MicramPelis. 



The following is my census of the North American species 

 of Marah, as far as they are known to me ; though I may add 

 that while yet an ardent resident student of Pacific Coast 

 botany, I came to suspect that one or two of the accepted 

 species were aggregates.

An Oriental Convallaria. 



C0NVAI.1.ARIA Japonica. Rootstock short, very stout, 

 densely clothed and even quite concealed by rather hard fibrous 

 roots, its crown bearing a fibrous tuft, the remains of leaves of 

 former seasons ; leaves two only, subequal, elliptic, cuspidately 

 acute, neither face with any trace of bloom, both of a bright, 

 rather light green, the leaf as a whole of a notably fibrous 

 anatomy : peduncle short, its summit scarcely equalling, or 

 little more than equalling the bases of the leaves ; raceme 

 few-flowered, its bracts small, ovate-lanceolate, subscarious : 

 perianth widely opening, broadly campanulate or almost saucer- 

 shaped ; stamens large, very short, the round-oval very obtuse 

 anthers longer than the filaments. 



All the Japanese material that I have seen answers to the 

 above description, and is therefore by quite a redundancy of 

 them, perfectly distinct from C majalis. This oriental plant
