LOBELlACEAE (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.

 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-
