sessile ; Jls. in & terminal, bracted, secimd raceme ; sta. longer than the corolla. 

 — A tall species of superior beauty, frequent in meadows and along streams, 

 Can. to Car., W. to 111. ! Stem 2 — 4f high, often quite glabrous as well as the 

 whole plant. Leaves 2 — 4' by 8 — 15", usually denticulate. Flowers on short 



f)edicels, few or numerous, in "a superb, nodding raceme. Bracts linear-subu-

2. L. iNPLATA. Indian Tobacco. 



St. hairy, branched, erect ; Ivs. ovate-lanceolate, sessile, serrate, pilose ; 

 caps, inflated. — In fields and woods. Can. and U. S. Root fibrous. Stem 

 erect, very rough, angular, simple, becoming branched in proportion to the 

 luxuriance of its growth, 10 — 15' high. Leaves elliptical, sessile, hairy and 

 veiny. Flowers in leafy spikes, axillary, peduncled. Corolla small, pale blue, 

 leaving an oval, turgid capsule in the calyx. July — Sept. — This plant is ren- 

 dered famous by the Thomsonian physicians, in whose practice it appears to 

 be too indiscriminately used. Its specific action, as above stated, is that of a 

 violent emetic. In small doses it is powerfully expectorant. To its salivating 

 property is probably owing the driveling of horses in autumn.

 spreading, obtuse, submerged, having 2 longitudinal grooves. Flowers droop- 

 ing, pale blue. July.

 cence, 1 — 2' inches in length and half as wide, the lower ones broadest towards

 Calyx hairy at base. Corolla of a bright purplish-blue. July. 



6. L. spiCATA. Lam. (L. Claytoniana. Mx. L. pallida. Muhl.) Clay-
