Dear Sir: -- 
V/ill you kindly tell n© in what edition (and 
date of saiae) of the Manual “Stipa Richard sonii, Link" v/as first 
publislaed ? I msh to settle this point as Gray anc^Link pub- 
lished the description of the particular plan.t referred to. 
I have just received specimens of this Stipa fromMt. Desert, 
Maine, which increases its range somewhat. The true Stipa 
Richardsonii, Link^ is a western grass and is represented 
i** l 5, [., ,rt,9 
by No. S41 of iry Montana collection. ^ j* / *- ^ / 
The Eragrostis sent me sometime ago by Mr, Robinson fcr' 
name^ appears among some grasses recently sent me by Dr. Vasey, 
collected by Palmer in Mexico, in 1890, Vasey considered it 
new and on one ticket has it Eragrostis diversus, referring to 
the foliage, .On another t.icket, attached to anotlier speeimerj, he 
ff 
has (whether carelessly or not, I cannot say) written it Era- 
n 
grostis diversifloms, 
I vrould very much like to have your opinion on Pringle »s 
No. 3252 which I published as Leptochloa Mexicana, Palmer co*'-
