I am not aware that Torrey’s Peak (known in the vicinity by the — 
later name of Mount Irwin) has been ascended, though it appa- 
rently presents no special difficulties; and Gray’s Peak is usually 
selected for ascent, because a comparatively easy horse-trail has 
been prepared to the summit. When on Gray’s Peak, I ascertained 
by a pocket-level that Torrey’s Peak is a little the higher, though — 
the difference is slight, probably 50 or 100 feet, and I think this is 
confirmed by other observations.” { 
§ 87. Bromus Tectorum.—In the January number of the Bul- 
letin I notice, under the head of “Catalogue of Suffolk County 
Plants,” a remark with reference to Bromus tectorum. Abouteight _ 
years ago, I detected a species, new to this region, which by com- 
parison with an authentic specimen of the B. tectorum from Ger- 
many, preserved in my herbarium, I have regarded as identical with 
that plant. Having submitted it to the late Dr. William Darling- 
_ ton for inspection, he informed me that some time before, he had 
received specimens from a correspondent in Germantown, near 
Philadelphia. He at once referred it to the species above noticed. _ 
. Mine was gathered in the suburbs of our town, confined to one | 
- Spot, its introduction, no doubt, adventitious. By the extended — 
improvements of our town, the locality has been broken up. Ien- | 
close a small portion, which may prove sufficient for identification 
with the Suffolk County plant. Harimay JACKSON,

$ 88. Synopsis of the Flora of Colorado, by Thomas ©. Porter — 
and John M. Coulter. This is one of the “ Miscellaneous Publica-— 
tions,” relating to the U. S. Geological survey of the Territories 
now in progress under the charge ot the Department of the Interior. 
It is a work of 180 pages, and is not a mere enumeration of plants, — 
but, for all the species not described in the readily accessible 
“Manual” of Doctor Gray and the “Flora ot the Southern States” 
by Dr. Chapman, the descriptions are quoted, thus saving the 
_ Student from the necessity of referring to eas | SA and works | 
not usually to be found in a private library. We notice In an ad- 
vanced sheet of the “ American Journal of Science” for May, that — 
Prof. Daniel C. Eaton makes some rather severe strictures upon the - 
- manner in which credit is given in this work. We hope that Prof. 
_ Porter, who is apparently responsible for the literary portion of th 
_ work, may give a satisfactory explanation of what appears to have 
been an untortunate inadvertence. ee ete 
$89. Desmodium.—It may interest the readers of the Bulletin 
to know that Mr. Albert Commons has discovered another locality 
for the very rare Desmodium humifusum, Beck, in the south-east 
_ corner of Newcastle County, Delaware. Here, as in the Salisbury, _ a 
__ Maryland, locality (now destroyed), the plant is completely pros- 
_ trate, ramifying in every direction from the central root. Wi
