or quite closing the throat. Stamens 4, didynamous, in-

1. A. glandulosum Lindl. Stems stout, erect, 1-1.5 m. high, 

 glandular-pubescent and viscid throughout, destitute of prehen- 

 sile branches, leafy ; leaves lanceolate, mostly sessile above, 

 gradually passing into bracts of the leafy dense spike or raceme ; 

 sepals oblong-lanceolate, unequal, the longer equaling the cap- 

 sule; corolla rose-colored; filaments somewhat dilated above. 



Occasional in the San Gabriel Mountains in the chaparral belt. 



2. A. Nuttallianum Benth. Stems branched from the base, 

 the branches mostly procumbent, 5-10 dm. long, glandular- 

 pubescent throughout ; leaves ovate or subcordate, the largest 

 about 2.5 cm. long, nearly all distinctly petioled ; peduncles, at 

 least the lowest ones, longer than the flowers, sometimes disposed 

 to be tortile ; sepals shorter than the tube of the violet corolla ; 

 corolla about 8 mm. long, the lobes nearly equal; palate very 

 prominent; seeds almost alately costate. 



Occasional in sandy soil, especially toward the coast. 



3. A. subsessile Gray. Similar to the preceding but less dif- 

 fuse and erect, strongly glandular-pilose; leaves ovate, all sessile 

 or nearly so ; pedicels shorter than the somewhat larger flowers ; 

 lower lip of the corolla larger in proportion. 



Reported from Santa Catalina Island. Rather frequent on the mainland 

 about San Diego. 



4. A. Coulterianum Benth. Stem 5-10 dm. high, erect, or 

 gaining support by its filiform tortile branches acting as tendrils, 

 glabrous, except the inflorescence which is villous-pubescent 

 with viscid and often glandular hairs ; leaves distant, linear to 

 oval; spike virgate, 5-20 cm. long; pedicels shorter than the 

 calyx ; sepals linear or lanceolate, obtuse, all shorter than the 

 oval or ovate-oblong glandular-pubescent capsule ; corolla violet- 

 purple or usually white with yellowish palate, the lower lip large, 

 the tube about 6 mm. long. 



.Frequent in the lower portions of the chaparral belt of all our mountains 

 and occurring on the fans at the base of the mountains. 



5. A. strictum (H. & A.) Gray. Erect, nearly simple, 3-6 dm. 

 high, the tortile branches none; lowest leaves ovate-lanceolate,
