New Mexico: White Mountains. Pine woods, in the Transition Zone. 
Mr. M. E., Jones is of the opinion that this is the same species that Doctor Watson 
described as A. giganteus from the Davis Mountains of western Texas. He is probably 
correct, but the material of A. giganteus which we have seen is not of such a character 
as to make it possible to decide the question, and the original description is not com- 
plete. In case Mr. Jones is correct, the name of the species is A. giganteus S. Wats. 
with A. yaquianus S. Wats. and A. teranus Sheld.! as synonyms.

This is probably too close to A. thompsonae 8. Wats., and field study will be neces- 
sary to determine the status of the two.

Low mountains and foothills, in the Upper Sonoran Zone, 
This is one of the common loco weeds of the southern part of the State, occasionally 
causing considerable loss to stockmen,’ 
Astragalus mogollonicus Greene? we have not seen, but Doctor Greene assures us 
that he is well acquainted with A. bigelovii, its nearest relative, and that the two are 
distinct. It should be found when the region from which it comes (‘‘bleak grassy 
summits of the Mogollon Mountains”) has been more thoroughly explored. Doctor 
Greene originally published the following comparison: ‘‘As compared with its nearest 
ally, A. bigelovii, the plant is a dwarl, being barely a span high. Its still smaller 
pods are much more densely woolly, and nearly straight at maturity, in which latter 
character, however, the species is at variance with the rest of the Mollissimi.’’
