When I transferred Astragalus debilis (Phaca debilis Nutt.) 
to Homalobus, I thought that the specimens above cited be- 
longed to it and drew the characters of the pod from them. I 
have since found that they tepresent a species close to H. 
Bourgovii. M. E. Jones identifies Phaca debilis, with Astragalus 
Bodini Sheld., which is a true Phaca related to P. microcystis. 
A duplicate of the type of P. debilis, which is in the Torrey 
Herbarium, somewhat resembles P. Bodini in habit, but the 
calyx is not black-hairy and the leaflets are emarginate. Mac- 
bride admits Astragalus debilis as a member of the subgenus 
Homalobus, citing the following two species from Colorado: 
North Park, Osterhout 3, and Upper Platte, Geyer 3. The 
latter I have not seen but Osterhout’s plant clearly belongs 
to P. Bodini. Osterhout had labelled it ‘Astragalus debilis,”’ 
apparently following Jones’s interpretation. Until the fruit 
is discovered, I fear that P. debilis can not be fully interpreted. 
Astragalus grallator S. Wats. is regarded by M. E. Jones as 
an abnormal form of A. Haydenianus, and I am inclined to 
agree to this view. In this case the species should be removed 
from Homalobus. The specimen of A. graljator in the Torrey 
Herbarium, so named by Watson, is a similar abnormal form 
of some other species.
