parts of the outer petals. The stigma is apparently 2 cleft, each 

 part again slightly divided into two small lobes. The pistil is 

 ovoid and bears the remainder of the withered persistent corolla 

 as in the yellow Calif ornian allies, and in Adhmiia, and this is a 

 notable character in these segregated recognized genera. 



As to the vegetable characters of habit, the plant bears at 

 its base which is buried deep in the ground a cluster of fusiform 

 tuberous roots above which are found in membranous leaf-scales 

 which cormlets or bulblets. The plant therefore appears to use 

 the latter only for propagation and the tuberous roots for food 

 storage. The scape and leaf petioles are buried imder ground 

 yi-^i of their length and the subterranean parts covered with 

 outgrowths like root-hairs which seem to serve the function of 

 absorbing moisture like roots. This last character is notable in 

 a plant which is not only essentially glabrous itself, but shares 

 that character with the whole group. 



Corniveum nov. gen. 



Planta glal^ra vel glauca perennis acaulis e radicibus fusi- 

 formibus tuberosis oriens, foliis ternatis dissectis, petiolis et scapo

 tatem unitis; petalis exterioribus semicordatis apice longe re- 

 curvatis, petalis interioribus hastatis unguiculatis, minime cristatis, 

 apice rotundato (unguis fere dimidio totius partis longus), scapo

Despeleza nov. gen. 



The type species of the genus Lespedeza Michx. is L. virginica. 

 There is another group of plants which has hitherto been 

 associated with this genus usually, but which has characters as 

 a group warranting separation therefrom. The absence or
