 volvulus sepium.) 



1. J. MONTANA L. Annual or biennial, 2-5 dm. high, simple or branching ; 

 leaves linear or lanceolate ; flowers blue, in heads 1-2 cm. broad. Fields and

LOBELIACEAE (LOBELIA FAMILY) 



Herbs, with acrid milky juice, alternate leaves, and scattered flowers, an irreg- 

 ular gamopetalous 5-lobed corolla, the 5 stamens free from the corolla and united 

 into a tube commonly by their filaments and always by their anthers. Calyx- 

 tube adherent to the many-seeded pod. Style 1 ; stigma often fringed. Seeds 

 anatropous, with a small straight embryo, in copious albumen. Often united 

 with the preceding family. 



1. LOBELIA [Plumier] L. 



Calyx 5-cleft, with a short tube. Corolla with a straight tube split down on 

 the (apparently) upper side, somewhat 2-lipped ; the upper lip of 2 rather erect 

 lobes, the lower lip spreading and 3-cleft. Two of the anthers in our species 

 bearded at the top. Pod 2-celled, many-seeded, opening at the top. Flowers 

 axillary or chiefly in bracted racemes ; in summer and early autumn. (Dedi- 

 cated to Matthias de VObel, an early Flemish herbalist.)

 gated, rather _l-sided, the pedicels much shorter than the leaf-like bracts ; the 

 large corolla intensely red, rarely rose-color or white. Low grounds, s. N. B. 

 to Ont. , and southw. Hybrids with the next species occur. 



* * Flowers blue, or blue variegated with white.

 at both ends, 0.5-1.5 dm. long, irregularly serrate ; flowers nearly 2.5 cm. long, 

 pediceled, longer than the leafy bracts ; corolla light blue, rarely white ; calyx
