Gen. Char. Calyx five-cleft. Corolla one-petalled, irregular. Cap-

The root is perennial, and furnished with innumerable small white fibres; the stem is upright, strong, simple, smooth, and rises from two to three feet in height; the leaves growing near the top of the stem are oval and pointed, those at the bottom rather elliptical, and obtusely lance-shaped; they are both minutely serrated, veined, smooth, and without footstalks; the flowers are numerous, large, blue, and grow upon a long spike, on short peduncles; the corolla consists of a long tube, which is nearly cylindrical, and divided at the limb into five pointed oval segments, of a rich blue color; the calyx is composed of five halbert-shaped leaves, fringed at the margin, and reflected at each side; the filaments, are five, tapering, equal in length to the tube of the corolla, and closely connected at the top by the anthers; the germen is short and conical; the style is about the length of the stamens, which terminates with a blunt, hairy stigma; the capsule is oval, and divided into two cells, which contain many small seeds.

Lobelia, of which there are at least fifty different species, was first introduced to botanical notice by M. Lobel, physician and botanist to James I., of England, from whom the plant derived its name.
