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. Watsont. 
Chenopodium Wolfii sp. nov. 
Chenopodium olidum S. Wats. Proc. Am. Acad. g: 95. 1874, 
partly. 
Annual, sparingly mealy: stem erect, 3-4 dm. high, often 
branched, striate: leaves moderately thick, dark green, only 
slightly mealy ; petioles about 1 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 1 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 t dm. high: stem branched, 
straw-colored or pinkish, almost glabrous: leaves subsessile, 
usually less than 1 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 &. 
Suckleyana Torr. 
In my opinion Dr. Torrey was correct in separating Endolepis 
from Atriplex. It is interesting to find a second species of the 
former genus, which hitherto has been known as monotypic. The 
original Exdolepis has narrowly lanceolate leaves, which are thin- 
ner and without lateral ribs.
