248 Rydberg : Studies on the 



it. Mr. Powell sent some seeds to Elihu Hall. A specimen raised 

 from these seeds and preserved in the herbarium of Columbia Uni- 

 versity I take as typical C. Watsoni. 



Chenopodium Wolfii sp. nov. 



Chenopodmm olidum S. Wats. Proc. Am. Acad. 9: 95- 1874, 

 partly. 



Annual, sparingly inealy : stem erect, 3-4 dm. high, often 

 branched, striate : leaves moderately thick, dark green, only 

 slightly mealy ; petioles about i cm. long ; blades 1-3 cm long, 

 oblong to ovate-lanceolate, entire or rarely slightly hastately 

 toothed, obtuse : inflorescence dense, narrow : flowers small : 

 seeds less than i mm., usually .75 mm. in diameter : pericarp thin 

 and easily separated from the seed. 



Closely resembling the preceding in habit, but is easily distin- 

 guished by the smaller flowers and seed and the separating 

 pericarp. These characters place it nearest to C. oblongifolium 

 Nutt., from which it differs in the less mealiness and the smaller 

 seeds.

Endolepis ovata sp. nov. 



Low, annual, usually less than i dm. high: stem branched, 

 straw-colored or pinkish, almost glabrous : leaves subsessile, 

 usually less than i cm. long, ovate or lance-ovate, 3 -nerved at the 

 base, sparingly mealy : pistillate flowers solitary in the axils of the 

 middle leaves : staminate flowers in small clusters in the axils of 

 the upper leaves or at the end of the branches, otherwise as in E. 

 StLckleyana Torr. 



In my opinion Dr. Torrey was correct in separating Endolepis 

 from Atriplcx. It is interesting to find a second species of the 

 former genus, which hitherto has been known as monotypic. The 

 original Endolepis has narrowly lanceolate leaves, which are thin- 

 iner and without lateral ribs.
