TORREY TO SCHWEINITZ 
NEw York. Sept. 11th, 1823. 
My Dear Sir— 
I forgot, in my hurry yesterday, to request your opinion on 
a subject to which I beg you will answer me immediately. I 
I have occupied most of my leisure time, during several days 
past, in examining a very interesting grass collected by Dr. James 
during the expedition under Maj. Long. After I had finished my 
description and drawing, which I prepared for publication in the 
Ist No. of the Annals of the New Lyceum [88*], I began to suspect 
my grass was not new, & I have therefore stopped the press while 
I hear from you on the subject. If I mistake not a specimen was 
‘sent you some time since, labelled—‘‘ Herb. James. No. 9,” but 
lest this should not be the case I inclose you some of the flowers— 
with a rough sketch of the plant [t] which I hope will be suffi- 
cient for you to make up your opinion respecting it— 
The flowers are spiked & heterogamous—Spikelets 3 at each 
joint of the rachis, sessile, surrounded at the base by a villous 
involucrum. Central spikelet hermaphrodite, 1-flowered. Calyx 
2-glumed, glumes orbiculate, 2-cleft, 5-bristled between the 
divisions. Cor. 2-valved, hyaline; inferior valve with a short 
bristle at the top. Lateral spikelets male. Calyx 2-glumed, 
2-flowered inferior glumes with a noc on one side below the 
middle. Corolla 2-valved, unarmed. 
By dissecting the inclosed congeries of spikelets you will see 
whether I am right in my dissections & description. The genus to 
which I fear my grass belongs (for I hoped it was a new genus) ** 
is Aegopogon of Humb. & Bonp., but it differs from that, which 
has the spikelets pedicellate, corolla with the inferior valve 3-
