I spikelet at each joint of the rhachis, in stronger ones the lower 
spikelets are in pairs and the upper ones single ; frequently some 
of the spikelets have three glumes, even some of the double ones, 
i. e., one glume on each side and one in front. Spikelets one to 
three-flowered, empty glumes linear-lanceolate, rigid, scabrous, 
mostly three-nerved, 3 to 4 lines long, and running into 
an awn as long or longer; flowering glumes oblong-lauceolate, 
punctulate below and scabrous above, 4 or 5 lines long, with 
an awn as long or longer, five-nerved ; palet equaling the glume, 
obtuse. 
_ ELYMus NITIDUS.—Culms 2% to 3 feet high, rather stout 
and leafy, sterile shoots half as long; leaves erect rigid, scabrous, 
6 to 8 inches long, 2 to 3 lines wide, slender pointed; ligule 
nearly obsolete; sheaths scabrous; spike about 4 inches 
long, erect; spikelets 1 or 2 at each joint, three to five-flow- 
ered; empty glumes 6 to 7 lines long including the awn, 
the upper one five-nerved, lower one three to four-nerved, 
scabrous on the nerves; flowering glume about 5 lines long 
with a fine scabrous awn of equal length, obscurely five-nerved, 
smooth or nearly so, punctulate and shining; palet a little shor- 
ter, ciliate-scabrous on the nerves. 
The spike is less thick than in &. Virginicus, and more com- 
pact than in Z. striatus. Collected by Mr. W.C. Cusick on the 
Eagle Mountains in Oregon. Grows in dense tufts, 1 to 2 
feet across. 
A New Moss from Oregon. 
The following description of a new species of Orthotrichum 
was furnished by Dr. Carl Miiller, made from specimens sent to 
him by Eugene A. Rau: 
ORTHOTRICHUM (Euorthotrichum) PRINGLEI, C. Miill, n. sp. 
Dioicum, caespites elati triunciales laxi flavi; caulis flexuosus ir- 
regulariter dichotome divisus gracilescens flaccidus laxifolius; folia 
caulina elongata horride imbricata madiore valde flexilia patentis- 
sima vel recurvata, e basi brevi angustiuscula semiamplexante 
margine revoluta in laminam elongatam lanceolato-acuminatam 
carinatam margine erectam ob papillas crenulatam apice subulato 
acutatam hyalinam protracta, e cellulis minutis rotundatis flavis 
scabro-papillosis basi folii elongatis densis glabriusculis magis
