1, LINARIA, Tourn. 



Calyx 5-parted. Corolla with the throat nearly closed; the base in front (below) pro- 

 longed into a spur. 



1. L. Canadensis, Dum. (Toad Flax.) Smooth; leaves linear, alternate on the 

 erect flowering stems, but smaller and broader ones often opposite or whorled on the 

 procumbent shoots; flowers blue in a terminal raceme. 



2. ANTIRRHINUM, Tourn. Snapdeagon. 



Like Linaria, except that the corolla has a saccate protuberance instead of a spur. Lj 

 ours the upper lip is spreading and the lower lobes deflexed. 



1. A. glandulosum, Lindl. Glandular and viscid; leaves lanceolate, mostly sessile; 

 flowers in a dense spike or raceme, half an inch or more long, jjink with yellowish 

 palate. 



2. A. vagans, Gr. Very diffuse, often glandular, branchlets frequently prehensile; 

 leaves short, lanceolate to ovate; flowers scattered, purplish blue, half an inch long. 



Var. Bolanderi, Gr. Has broader and thinner leaves, those on the prehensile branch- 

 lets orbicular. 



3. A. Bre-weri, Gr. Has smaller flowers, only 3 lines long; style strongly deflexed. 



3. SCROPHULARIA, Tourn. Figwort. 



Calyx deeply 5-cleft, the lobes broad. Corolla short, with an oblong tube unequally 

 5-lobed, 4 erect, the two upper the longer. Stamens 4, inserted in pairs, low down on 

 the corolla tube, a rudiment of the fifth stamen in the form of a scale above. Coarse 

 herbs, with inconspicuous flowers. 



1. S. Californica, Cham. Nearly smooth, 2 to 6 ft. high, with deltoid or truncate- 

 ovate doubly toothed opposite leaves; flowers small greenish or lurid red (rarely yellow) 

 in a terminal thyrsus. 



4. COLLINSIA, Nutt. 



Calyx deeply 5-cleft. Corolla with the tube gibbous or saccate on the upper side, 

 commonly declined, conspicuously bilabiate; the upper lip 2-cleft, and its lobes recurv- 

 ing; tlie lower 3-lobed and larger, its side lobes pendulous-spreading, the middle one 

 folded into a keel-shaped sac and including the declined stamens and style. Stamens in 

 pairs, with long filaments, anthers round-reniform. A gland at the base of the corolla on 

 the upper side answers to the fifth stamen. — Beautiful annuals with simple opposite or 

 whorled leaves, all but the lower sessile; pedicels solitary or whorled in the axils of leaves 

 which diminish to small bracts above.
