new species, and unless I can find the same char- 
acters in viridiflora I shall call it S. alata. 
Can you give me any light ? I have not yet seen 
S. viridiflora. 
I have also studied your Cercocarpus intrica- 
tus and my C. ledifolius var. intricatus and th 
think I ca.n say the last word on the subject. I 
have found abundant transitions on all the raoun- 
where bothy^ occur from the V/asatch to the East 
Humblodts. ledifolius is a high altitude plant^ 
while the other" is a low altitude plant but runs 
up into the range of the former and overlaps it 
at its lower range. The pubescence is of no accou^sfT' 
as a character and the variations in the leaves 
a.nd flowers ^ 
are such that I fear C. par breviflorus must drop 
into it as a form a,s well as ray C. Arizonicus. I 
a.m not prepared to say that I believe it but I 
fear this will be the conclusion. If intricatus 
is retained as a species, then the other two will 
have still greater right, for they never show 
transition to ledifolius because they do not grow 
where it is found. I have made a study of this 
plant and the flowers of Astragalus in which lat- 
some important characters have been overlooked. 
V/ell, I ha.ve written more than I intended. 
Very truly yor""
