CATALOGUE. 7 J 



Cerastium nutans, Raf.— Sierra Blanca, Arizona, at 9,000 feet altitude 

 (803), and Mount Graham (403). 



Ceeastium arvense, L.— South Park and Blue River, Colorado. (348, 

 350, 351, 353.) 



Stellaria Jamesii, Torr.— Colorado (339), Nevada, and Utah. 

 Stellaria longipes, Goldie —Colorado. (338, 340.) The plant (340) 

 from Colorado, which I published and distributed as &'. hngifolia, is without 

 doubt S. longipes. 



Stellaria crassifolia, Ehrhaft. — Nevada. 



Arenaria saxosa, Gray (PI. Wright, 2, p. 18).— Perennial, 5-12' 

 high, slightly hispid-pubescent ; leaves sessile (lower ones sub-connate at 

 base), lanceolate acute, 6" long, 1-2" wide ; raceme many-flowered, some- 

 what cymose, pedicels J-f ' long ; sepals very acute, somewhat, scarious- 

 margined, with a distinct, almost keel-like midrib, which is decidedly hispid; 

 the obovate white petals as long as, or a little longer than, the sepals. (412.) 

 Mount Graham, Arizona, at 9,000 feet altitude. 



My specimens appear decidedly more luxuriant than those on which 

 the species was founded. The distinctive features are so well marked, 

 however, that I can hardly consider it as anything else. 

 Arenaria capillaris, Poir — Utah. 



Arenaria Fendleri, Gray (PI. Fendl. p. 13).— South Park, Colo- 

 rado (349), and near Cosino Caves, Arizona, in pine ivoods. Loew, col-

 Colorado, 1 1,003 feet altitude (868) ; Utah. 



Arenaria verna, L.— Mosquito Pass, Colorado. (345.) 

 Var. iiirta, Fenzl. — More densely csespitose than the typical A. verna; 

 leaves broader, rougher, and obtuse ; flowering stems shorter. South Park, 

 Colorado. (346.) 



Arenaria (Alsine) biflora, Wahl— Under this 1 include all the 

 numbers 364, 343, 344, representing respectively the names A. arctica, 

 Stev., var. obtusa, A alpina, L., A Rossii, R. Br, of the catalogues of the 

 Colorado collection. It was by a clear inadvertency that the name A 

 alpina, L., was used at all, as it does not, so far as I can find, appear any-
