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, Arizona, 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 Palmerella 

 debilis, var. serrata, Cray, a new and interesting genus of this order, and 

 Plate XVI of this volume for its figure. 



Specdlaeia peefoliata, A. DC. {IDysmicodon perfoliatum, Nutt.) — Ash 

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



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

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



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



Campanula L.ANGSDORFFiANA,f Fisch — Differing from O. uniflora, 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." 



~ebigagem. 



Vaccinium c&spitosum, Michx. — South Park, Colorado (741). 



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

 bright 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. 



Arctostaphylos Uva-ursi, 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. 



* Akbutus, Tourn. — Corolla gamopetalous ; calyx free. Ovary 5-celled, raised on a disk. Stamens 

 10, included ; anthers opening by pores and having 2 reflexed awns on the hack. Placentas thick, on 

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



tNow assigned by Dr. Gray (Syn. Fl. part 1, p. 12) to C. Sclieuzeri, Vill., var. helerodoxa, Gray.
