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. 



Marah fabacea. Naudin under Echinocystis. 



MURICATA. Kellogg. 



macrocarpa. Greene under Echinocystis. 

 GiLENSiS. Greene 



Oregana. Torr. & Gray " Sicyos. 



GuadalupEnsis. Watson " Meganhiza. 



RuSBYi. Greene " Micrampelis. 



LEPTOCARPA. Greene 



Watsonii. Cogn. " Echinocystis. 



An Oriental Convallaria. 



CoNVALLARiA 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
