11. A. Cooperi, Gray, 1. c. Climbing (2 or 3 feet) by the long filiform pe- 

 duncles : stems very slender, at length much branched : lowest leaves ovate or 

 oblong, the others linear, and the upper floral minute : corolla bright yellow (half 

 an inch long), conspicuously saccate at base; the palate hairy: style deciduous from, 

 the thin-walled capsule : seeds rough-rugose and with 3 or 4 corky ribs. 



Ravines on the Moliave, Cooper, Almendinger. Also Southern Utah, Parry. 



12. A. filipes, Gray. More delicate than the preceding, with broader and 

 thinner leaves, very capillary tortile peduncles, and very small flowers : corolla 

 "white," little exceeding the calyx. Bot. Ives Colorado Exp. 19. 



Desert arroyos on the Arizona side of the Colorado. Perhaps a depauperate form of A. Cooperi, 

 with imperfectly developed corolla. 



* * Perennial, climbing by the slender tortile petioles and axillary peduncles : leaves 

 lobed or cordate : calyx longer than the globular capsule. 



1 3. A. maurandioides, Gray. Either low or tall-climbing, glabrous, slender : 

 leaves triangular-hastate or more cordate, the lobes at base often with a posterior 

 tooth: corolla (purple or sometimes white, 6 to 12 lines long); its palate nearly 

 closing the throat : sepals lanceolate, very acute : style slender : seeds corky-ribbed.

 Willd. Hort. Berol. t. 83; Bot. Mag. t. 1643. 



A Mexican and Texan species, common in cultivation, extending westward through Arizona to 

 or near the Colorado. 



3. Shrubby and erect : leaves mostly opposite or in threes, evergreen, entire : corolla 

 tubular with short lips : the smooth palate prominent, but not closing the 

 throat : capsule globose, not oblique : style straight, slender : seeds as of the 

 preceding sections. GAMBELIA, Gray. (Gambelia, Nutt.) 



14. A. speciosum, Gray, 1. c. A much-branched shrub, 3 or 4 feet high; 

 the young parts soft-pubescent, the older glabrous, at least the oval or oblong 

 thickish and firm leaves (these an inch or two long and half to an inch wide) : 

 flowers in short terminal racemes and in the axils of the upper leaves : pedicels like 

 the leaves or bracts usually verticillate : corolla scarlet, hardly an inch long ; the 

 tube cylindrical except the gibbous base, twice or thrice the length of the narrowly 

 lanceolate sepals, 3 or 4 times the length of the short lips : stigma entire or emargi- 

 nate : capsule pubescent, opening by a chink on each side of the slender straight 

 style : seeds oblong, truncate, strongly rugose-ribbed. Gambelia speciosa, Nutt.

Island of Catalina, Gambel. Also Guadalupe Island, off Lower California, in flower and fruit, 

 Palmer. A showy shrub, with bright red flowers ; these pubescent outside : the foliage not un- 

 like that of Oestrum diurnum. 



15. A. junceum, Gray, 1. c. Perhaps shrubby, glabrous, 2 feet high: leaves 

 small, oblong-linear : tube of the corolla 8 lines long. M. juncea, Benth. Bot. 

 Sulph. 41. 



From San Diego to Bay of Magdalena in Lower California, Hinds. Not since seen ; perhaps 

 same as the preceding. 



SACCULARIA VEATCHII, Kellogg, Proc. Calif. Acad., from Cerros Island, off Lower California, 

 which has been conjectured to be a Russellia, is probably a form of Galvesia Limensis, a shrubby 

 plant of the Pacific coast, near the last section of Antirrhinum. 



4. MOHAVEA, Gray.

Calyx of 5 lanceolate acuminate and nearly equal sepals. Corolla with short tube 

 merely gibbous at base in front, and a very ample and bilabiate but somewhat cam- 

 panulate- erect limb ; the lips broad and almost fan-shaped ; upper one 2-lobed ; the
