sessile ; fls. in a terminal, bracted, secund 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

2. L. INFLATA. Indian Tobacco. 



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

 caps, inflated. — (I) 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. 



3. L. DoRTMANNA. DoHmann^s or Water Lobelia.

 nearly naked ; fls. in a terminal raceme, remote, pedicellate, nodding. — % A

 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 

 the end. Flowers large, on very short pedicels, each solitary in the axil of an 

 ovate-lanceolate bract, forming a somewhat one-sided raceme, leafy below. 

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