2. ANTIRRHINUM L. Snapdragon. 

 Annual or perennial herbs with the lower leaves opposite and the 

 upper leaves alternate. Corolla gibbous or saccate at base on lower

 base of the style; style (in our species) persistent and often de- 

 flexed. (Greek anti, like, and rhinon, nose, because of the snout- 

 like flowers.) 



Perennials; no tendril-like branches. 

 Leaves linear; sepals the length of the corolla . . . . 1. A. rirga. 



Leaves lanceolate; sepals equaling or shorter than the corolla 



2. A. gland ulosu m. 

 Annuals ; branches or peduncles disposed to be prehensile. 

 Peduncles about 1 line long; branchlets slender or filiform, at length 



twisting 3. A. vagans. 



Peduncles 2 to 3 in. long, filiform, prehensile 4. A. striatum. 



1. A. virga Gray. Glabrous, erect, with many virgate stems from 

 a perennial base, 1\ to 5 ft. high; leaves linear, 2 to Z\ in. long, 

 sessile; flowers red-purple in a mostly secund raceme, with subulate 

 bracts; sepals ovate, acute, moderately unequal, scarcely half the

 miform; lower pair of filaments dilated at apex, all geniculate at the 

 very base and all hairy, especially at the geniculation or knee; cap- 

 sule dehiscing by pores at the base of the style; seeds with the longi- 

 tudinal wing-like ridges fimbrillate. 



But few stations known: Howell Mountain; Mt. St. Helena and

2. A. glandulosum Lindl. Stem stout, branching, 3 to 5 ft. 

 high, very leafy; herbage glandular-pubescent; leaves lanceolate, 

 sessile, gradually diminishing into the bracts of the inflorescence; 

 bracts equaling or shorter than the oblong tube of the corolla; sep-

 upwards." 



Mt. Hamilton (acc. to Greene); Santa Cruz, and southward. 



3. A. vagans Gray. At first simple and erect, at length branch- 

 ing and very diffuse, the branches »i to 18 in. long; slender or filiform 

 branchlets more or less twisting and disposed to be prehensile; leaves
