2. L. iNFi.ATA. 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 Tliomsonian 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.
