52 THE AMERICAN BOTANIST 



On October 2, 1917, I found the same plant again in 

 abundance in vacant lots and by neglected walks in Hastings, 

 Nebraska, (No. GG07) not far from the Burlington Road, — 

 that is, within three blocks. The Naponee collection, made on 

 the railroad banks, is the best developed, having membranous 

 calyx wings 2 mm. long without a trace of angularity or 

 thickening. I therefore name the plant 



KOCHIA ALATA N. SP. 



The species may be described thus : Annual, spreading, 

 not at all upright as is K. scoparia, obscurely pyramidal, 

 stouter; stem puberulent; leaves much as in scoparia, strigose- 

 pubescent on the underside, not pilose with long hairs on the 

 margin as in my specimens of scoparia ; inflorescence dense, 

 giving a heavy appearance, branches with inflorescence some- 

 times longer than the plant is high, not at all reduced at matur- 

 ity of seed, lightly to densely lanate with white or brownish 

 hairs. Calyx developed into membranous wings 1 to 2 mm. 

 long, dirty white, heavily veined, more or less erose-dentate, 

 obovate, distinct. 



If the habit of this plant was like that of K. scoparia, I 

 would not think of calling it a new species. I have taken the 

 Hastings plant as the type because it is established there be- 

 yond doubt and is easy of access. I shall study it further this 

 season. Specimens have been deposited in the University of 

 Nebraska, University of Wyoming, in New York Botanical 

 Garden, and will be sent to Washington at once. The name, 

 however, has not been attached to the plant until the present.
