This is the form *' differing from the type in its large and spread- 
ing, usually much crowded spikelets, and its long, stout and diver- 
gent awn," referred to by Dr. Thurber in his remarks under Triti- 
cum cafiinum^ in Bot. CaL, p. 324. It is certainly very distinct from 
the ordinary forms of the species, and should at least have a varietal 
name — say var. majus.

Note on Cyperus refractus, Eng.— For several years past I 
have frequently collected in this locality a Cyperus which I could 
not make correspond with any species in Gray or Chapman. On 
a recent visit to Cambridge I took occasion to look up the subject, and 
found, in Dr. Gray's herbarium, specimens of the same species with 
the manuscript name of Cyperus refractus, Eng. On calling Mr. 
Watson's attention to it, he' recalled the fact of its publication under 
that name in Linna^a, Vol. xxvi., p. 369, in the description of the 
Cyperacese of the Berlin Herbarium, the type specimen having un- 
doubtedly been furnished by Dr. Engelmann. It is probably the 
same plant as is described in Steudel as Cyperus retrofractus, Eng., but 
is not the C retrofractus of Torrey. It is a tall, strong plant, 2 to 3 
feet high, with from 5 to 10 unequal rays, the longest frequently 10 
inches, naked except i or ^\ inches at the extremity. The spikelets 
are 8 to 10 lines long, about 6-flowered, spreading horizontally and 
becoming retrofracted. The nutlets are triangular, linear-oblong, 
about i^ hnes long. It is undoubtedly pretty widely diffused in the 
country.

Notes from Utah.— In "Fern Notes, VI.," Mr. Davenport speaks of 
Aspidium Filix-mas. This plant was discovered by me in August, 
1882, in quantity in the Wasatch Mts., Utah, and it undoubtedly 
ranges through all the higher mountains of Colorado, Utah, Nevada, 
etc.
