A. integrifolia? Torr. loc. cit. is so imperfect that we can not very 
confidently refer it to the present species; but it certainly is not 
the same with the foregoing” [A. Torreyana]. 
When preparing the manuscript of the Flora of Colorado, 
I overlooked the publication of Tetraneuris epunctata A. Nels. 
Otherwise I should not have proposed T. glabriuscula to replace 
the untenable T. glabra Greene. I am perfectly willing to reduce 
the last two to synonymy. This is, however, not the case with 
T. angustifolia. In the key Professor Nelson has a division, 
“Crowns of the caudex short” in contrast to ‘Crowns of the 
caudex fastigiate and elongated, 1-2 dm. high.”’ Under the first 
division he includes Actinella linearis. If he had given A. an- 
gustifolia instead it would have been correct. The type of Ac- 
tinella scaposa linearis was collected by Riddell in Texas and is 
preserved in the Torrey herbarium. It has elongated branches 
of the caudex as have Tetraneuris fastigiata and T. stenophylla, 
and differs from them mainly in the fact that the bases of the 
leaves are scarcely dilated. I think that Tetraneuris fastigiata 
and T. stenophylla also are distinct. This is only a matter of 
difference in opinion as to limitation of species. If they are to be 
united, they should be included in T. linearis, which is just as 
closely related. Tetraneuris angustifolia on the contrary is more 
distinct and related to 7. Torreyana, but lacks the hair-tufts at 
the bases of the leaves. 
Tetraneuris mancosensis A. Nels. is a synonym of Actinella 
leptoclada A. Gray. 1 am now inclined to regard T. inter- 
media Greene also as such, although I kept it distinct in the 
Flora of Colorado. But I think it goes too far in “lumping,” 
if one tries to include the acaulescent Tetraneuris Crandallit, 
T. arizonica, and T. pilosa in the leafy-stemmed T. leptoclada. 
Besides the difference in habit the acaulescent species have abruptly 
aristate pappus-scales, while in T. leptoclada the scales taper 
gradually into the bristle-point. Tetraneuris Crandallii in habit 
closely resembles T. Torreyana, but the scape in not villous and 
the pappus is different. T. arizonica, in which I am inclined to 
include T. pilosa, resembles T. epunctata, but the leaves are more 
hairy, more punctate, and have conspicuous hair-tufts at the bases- 
It seems as if enough species have been proposed in this genus,
