CATALOGUE. 183 



bracts 5-8" long, hardly exceeding the filiform, sigmoid, or curved pedicels; 

 calyx-tube turbinate, half as long as the acute, ciliolate lobes, sinuses not 

 appendaged ; tube of the corolla 3" long, exceeding the calyx; two inferior 

 anthers hairy-tufted at the apex, and the others pubescent on the back 

 Flowers violet-blue. — Sierra Blanca, Ai-izona, at 7,000 feet (797), and also 

 collected by Dr. Loew on Quevelono Fork, Arizona 



Mr. Watson has kindly compared this for me with specimens in the 

 Cambridge Herbarium, and I cannot doubt his conclusion, but I am bound 

 to say the plant poorly accords with the description given in DC. Prod. 

 7, 373. See Fl. California, 1, p. 619, for the description of Palmcrella 

 dehills, var. serrata, Gray, a new and interesting genus of this order, and 

 Plate XVI of this volume for its figure. 



Speculaeia peefoliata, A. DC. (Dysmicodon perfoliatum, Nutt.) — Ash 

 Creek, Arizona (314), at 5,000 feet. 



Campanula eotundifolia, L. — Mount Graham, Arizona, at 9,250 feet 

 (414) ; Colorado, Grant Post Office (752). 



Campanula unifloea, L. — Grant Post Office, Colorado (751). 



Campanula Langsdobffiana,! Fisch — Differing from G. wiiflora, L., in 

 having an "obconic ovary''; calyx glabrous and the "lobes serrulate on 

 the margins". The flower, too, is larger, i. e., " 1' in diameter." 



EPJCACE.E. 



Vacoinium CuESPitosum, Michx. — South Park, Colorado (741). 



Aebutus* Menziesii, Pursh. — Leaves oval, serrulate, pale beneath and 

 1 night green above; racemes dense, minutely tomentose ; corolla almost 

 globular, white ; berries dry, orange- colored, with surface granulate. — 

 Santa Rita Mountains, at 7,050 feet altitude. 



Aectostaphylos Uva-uesi, Spreng. — Mountain parts of Colorado (742). 

 Said by the late accomplished author of Fl. Bor Amer. to be used by natives 

 of the Northwest to weaken their tobacco; rather, I should say, to eke it out. 



* AitBUTUS, Touru. — Corolla gamopetalous ; calyx free. Ovary 5-ceIled, raised on a disk. Stamens 

 10, included; anthers opening by pores and baving 2 rellexed awns on the back. Placentas thick, on 

 the inner angle of each cell. Berry rough, several seeds in each cell. The Madrono of the Southwest 

 and Pacific slope, which, toward its southern range, becomes a large tree, but, as seen by me in Southern 

 Arizona, is not over 20 feet high and 2 feet in diameter. Used by the Mexicans in the manufacture of 

 stirrups, etc. Wood hard. 



t Now assigned by Dr. Gray (Syn. Fl. part 1, p. 12) to C. Scheuscri, Vill., var. heterodoxa, Gray.
