Actinella glabra Nutt. 1841. 
What Actinella glabra Nutt. was is not exactly known. It is 
not, however, the plant for which Dr. Greene adopted the name 
' Tetraneuris glabra. If it isa Zetraneuris at all, it must be a spe- 
cies related to 7. Ivesiana, T. argentea and T. leptoclada, as it is 
described as having stem-leaves. None of these grows near the 
original locality of A. glabra, viz., Shawnee villages on the Missouri 
(near Kansas City). The only species that are found within 300 
miles from this station are 7. herbacea Greene of Illinois, and 7. 
fastigiata Greene and the following from central and western Kan- 
sas. None of these answers the description. 
Tetraneuris stenophylla Rydb. 
Perennial with a branched caudex, the branches of which are 
partly subterranean, 2-10 cm. long; leaves basal, very narrowly 
linear-oblanceolate, 2-4 cm. long, I-2 mm. wide, strongly pane 
tate, glabrous or with a few long hairs near the base ; bases dilated 
and scarious-margined, only slightly long-hairy ; scape 5-10 cm. 
long, striate, punctate and sparingly strigose ; involucre about 5 
mm. high and 10 mm. wide, hemispheric ;_ bracts elliptic, obtuse ; 
rays light-yellow, about 10 mm. long and 5 mm. wide, 3—4-toothed 
and 5—7-nerved. 
This is closest related to 7. fastigiata Greene, in which, how- 
ever, the bases of the leaves are arachnoid-hairy and the involu- 
cres densely villous.
