 * # Naturalized from the Old World. 



•)— Perennial, erect, 1 to .3 feet hiyli, glabrous, with narrow entire and alternate pale leaves, and 

 yellow flowers ill a terminal raceme. 



L. vulgAkis, Mill; (Hamsted, Bcttek & Eggs.) Leaves linear or nearly so, extremely 

 numerous ; raceme dense, often paniculate below : corolla an inch or more long, including 

 the slender subulate spur: seeds winged. — Fields and road-sides, Atlantic States: a 

 showy but pernicious weed. (Nat. from Eu.) 



L. GENiSTiFOLiA, Mill. Glaucous, paulculately branched : leaves lanceolate, acute : flow- 

 ers smaller and more scattered : seeds wingless. — = Sparingly naturalized near New York. 

 (Adv. from Eu.)' 



■y- -I— Annual, procumbent, and much branched, with broad and abruptly petioled reinj' alternate 

 leaves, and pui-plish and yellow small flowers from their axils. 



L. ElAtixe, Mill. Spreading over the ground, slender, hairy: leaves hastate or the lower 

 ovate, much surpassed by the filiform peduncles : calyx-lobes lanceolate, acute : corolla 

 3 or 4 lines long, including the subulate spur. — Sandy banks and shores, rather rare. 

 Canada to Carolina. (Nat. from Eu.) 

 s-L. SPURIA, Mill., like the preceding, but with roundish or cordate leaves and ovate or cor- 

 date calyx-lobes, and one or two other Old "World species occasionally spring up in ballast 

 or waste grounds near cities>^. Cymhaldria, Mill., a smooth and delicate creeping species, 

 is common in cultivation, but seldom becomes spontaneous. 



4. ANTIRRHf NUJVt, Tourn. Snapdragon. {AvtiqqIvov of Theophras- 

 tus, from the snout-like aspect of the flowers.) — Herbs, rarely shrubby, of very 

 various aspect, indigenous to the warmer parts of the Old AVorld and of North 

 America and jNIexico, in our species all or all but the lower leaves alternate. 

 Calyx deeply 5-parted. Cells of the anthers either distinct or more or less con- 

 fluent. 



§ 1. Orontiuji, Benth., partly. Capsule oblique, firm-coriaceous; the cells 

 opening by a definite hole at the top : seeds cup-shaped on ventral face, with 

 thickened incurved border, smooth and carinately one-ribbed on the back. 



A ■ Okon'tium, L. Annual, a span or two high, erect, slender, glandular-pubescent : leaves 

 oblong-linear or lanceolate, entire : flowers subsessile : corolla purple or white, half inch 

 long. — Cult, and waste ground, sparingly spontaneous in Atlantic States. (Nat. from Eu.) 



§ 2. PsEUDOEONTiUJi, Gray. Capsule not oblique, somewhat didymous, char- 

 taceo-membranaceous'; the equal cells irregularly bursting at the apex: seeds 

 strongly cup-shaped ; the body muriculate on the back and far smaller than the 

 involute wing. — Proc. Am. Acad. xii. 81. 



A. CTATHfFEEUM, Benth. Bot. Sulph. 40, t. 19, of Lower California, appears to differ from 

 the following in having linear-lanceolate sepals, of only half the length of the tube of the 

 corolla, and a shallower cup to the seeds. 



A. chytrospermum, Gray, 1. c. Annual, viscid-pubescent : stem a span to a foot high : 

 leaves ovate, entire, 3 to 9 lines long and contracted into a margined petiole : flowers 

 axillary, short-peduncled : sepals oblong-lanceolate, equalling the tube of the purple 

 corolla (this barely 3 lines long): cup of the seed several times larger than the body. — 

 Ehrenberg, Arizona, Palmer. 



§ 3. AntieehinAstruji, Chavannes. Capsule more or less oblique ; the per- 

 sistent style or its base bent forward : cells opening by one or two holes : seeds 

 rugose-alveolate or tuberculate, similar on the two sides : palate of corolla closing 

 the orifice or nearly so : leaves entire, pinnately veined, and with short petioles 

 or none.
