portion. The latter does not agree with the description of Ga- 
lardia acaulis. 
I have come to the conclusion also that Tetraneuris eradiata A. 
Nels. is but a rayless form of T. acaulis. My no. 106 contains both 
radiate and rayless specimens. The disk-flowers of T. eradiata 
are said to be “‘almost orange.’’ They usually turn more or less 
orange in age in T. acaulis and the type of T. eradiata is pretty 
well advanced in age. There are no other distinctive characters 
either in the description or in the specimens that I can see. 
Even Tetraneuris simplex is not too good a species and it is 
very close to T. acaulis on one hand and T. trinervata Greene on 
the other. The latter I had reported for Colorado in my Flora of 
Colorado; but it is wholly ignored by Nelson. As the New Manual 
includes northern New Mexico, the type locality even of T. 
trinervata, viz., Sandia Mountains, N. M., between Santa Fé 
and Albuquerque, is within the range. 
What Professor Nelson’s interpretation of Actinella acaulis 
really is, is hard to tell, for some of the specimens he has distributed 
under that name and Tetraneuris acaulis belong to T. lanata 
and others to T. acaulis caespitosa A. Nels. Most of them were 
distributed before the latter was segregated. Both E. Nelson 
4329, distributed as T. acaulis, and A. Nelson 4607, distributed 
as T. lanata?, match perfectly a part of the type of Nuttall’s 
Actinella lanata in the Torrey herbarium. All three are very 
young. 
It is evident that Actinella acaulis caespitosa A. Nels. is more 
closely related to A. Janata than to A. acaulis. It has the loose 
pubescence of A. Janata, a character best seen in age. I am in- 
clined to think that it is the same as Tetraneuris brevifolia Greene, 
although I have not seen the type of the latter. It should then 
bear that name, unless it is reduced to a variety of A. Janata. 
The plant was first collected by James in Long’s Expedition 
on James Peak (now Pikes Peak), the type locality of T. brevi- 
folia. Torrey* referred this specimen to Actinea integrifolia 
Kunth; but in Torrey and Gray’s Flora,t it was referred to 
Actinella lanata with the following remark: ‘““The specimen of
