H- -- Flowers blue or purple. 

 *- Corolla equaling or longer than the pedicels. 



3. L. canadSnsis (L.) Dumont. Slender,- glabrous; flowering stems nearly 

 simple, 2-8 dm. high ; leaves flat, 2-4 mm. wide ; racemes slender, naked, loose ; 

 corolla 1 cm. or less long, sometimes wanting (in reduced and cleistogamous 

 flowers). Sandy soil, N. B. and centr. Me., westw. and southw.

 by the filiform peduncles ; calyx-lobes lanceolate, acute ; corolla 0.5-1 cm. long, 

 including the subulate spur. (Elatinoides Wettst. ) Sandy banks, shores and 

 waste places, Mass, to N. C. and Mo., rather rare. (Nat. from Eu.) 



6. L. SPURIA (L.) Mill. Like the preceding, but with roundish or cordate 

 leaves and ovate or cordate calyx-lobes. (Eiatinoides Wettst.) Occasional on 

 ballast or waste grounds. (Adv. from Eu.) 



t- -- Glabrous. 



7. L. CYMBALA.RIA (L.) Mill. (KENILWORTH or COLISEUM IVY.) Leaves 

 reniform-orbicular, 5-9-lobed ; peduncles slender, becoming recurved in fruit ; 

 calyx-lobes lanceolate. (Cymbalaria Wettst.) Waste places and ballast; also

3. ANTIRRHINUM [Tourn.] L. SNAPDRAGON 



Calyx 6-parted. Corolla-tube saccate or gibbous in front, not spurred ; the 

 lower lip 3-lobed, spreading, developed at the base into a prominent palate, 

 which nearly or quite closes the throat ; upper lip erect, shortly 2-lobed. Sta- 

 mens 4, didynamous, included ; anther-cells distinct and parallel. Ours herba- 

 ceous plants with lance-oblong to linear entire leaves and axillary or racemose 

 flowers. (Name from avrl, in the sense of like, and pis, a snout, in reference 

 doubtless to the peculiar form of the corolla.) 



1. A. ORONTIUM L. Slender usually branched annual, pubescent or smooth- 

 ish ; leaves linear ; calyx-lobes linear, exceeding the capsule ; corolla purple or 

 white, 1-1.6 cm. long. Casual in fields, about dumping grounds, etc., rather 

 rare. (Adv. from Eu.) 



2. A. M\JUS L. Perennial, glandular-pubescent and somewhat viscid ; leaves 

 lance-oblong; calyx-lobes ovate or oblong, short; corolla crimson, white, or 

 variegated, 2-3 cm. long. Commonly cultivated, and occasionally found as an

4. COLLiNSIA Nutt. 



Calyx deeply 5-cleft. Corolla declined ; upper lip 2-cleft, its lobes partly 

 turned backward. Fifth stamen gland-like. Capsule 4-many-seeded. Slen- 

 der annuals or biennials, with party-colored flowers in umbel-like clusters, 

 appearing whorled in the axils of the upper leaves. (Dedicated to Zaccheus 

 Collins, Philadelphia!! botanist, 1764-1831.) 



1. C. v6rna Nutt. (BLUE-EYED MARY.) Slender, 1.5-6 dm. high; lower

 toothed; whorls about Q-flowered ; flowers long-peduncled ; corolla blue and
