WILD FLOWERS [43]
the scarcity of hummingbirds, which chiefly fertilize them. But how bees love the blue blossoms!
There are many cases where the pistil of a flower necessarily comes in contact with its own pollen, yet fertilization does not take place, however improbable this may appear. Most orchids, for example, are not susceptible to their own pollen. It would seem as if our lobelia, in elevating its stigma through the ring formed by the united anthers, must come in contact with some of the pollen they have previously discharged from their tips, not only on the bumblebee that shakes it out of them when he jars the flower, but also within the tube. But when the anthers are mature, the two lobes of the still immature stigma are pressed together, and cannot be fertilized. Nevertheless, the hairy tips of some of the anthers brush off the pollen grains that may have lodged on the stigma as it passes through the ring in its ascent, thus making surety doubly sure. Only after the stigma projects beyond the ring of anthers does it expand its lobes, which are now ready to receive pollen brought from another later flower by the incoming bumblebee to which it is adapted.
Linnaeus named this group of plants for Matthias de l'Obel, a Flemish botanist, or herbalist more likely, who became physician to James I. of England.
Preferably in dry, sandy soil or in meadows, and over a wide range, the slender, straight shoots of PALE SPIKED LOBELIA (L. spicata) bloom early and throughout the summer months, the inflorescence itself sometimes reaching a height of two feet. At the base of the plant there is usually a tuft of broadly oblong leaves; those higher up narrow first into spoon-shaped, then into pointed, bracts, along the thick and gradually lengthened spike of scattered bloom. The flowers are oft en pale enough to be called white. Like their relatives, they first ripen their anthers to prevent self-fertilization.
The lithe, graceful little BROOK LOBELIA (L. Kalmii), whose light-blue flowers, at the end of thread-like footstems, form a loose raceme, sways with a company of its fellows among the grass on wet banks, beside meadow runnels and brooks, particularly in limestone soil, from Nova Scotia to the Northwest Territory and southward to New Jersey. It bears an insignificant capsule, not inflated like the Indian tobacco's; and long, narrow, spoon-shaped leaves. Twenty inches is the greatest height this little plant may hope to attain.
Not only beside water, and in it, but often totally immersed, grows the WATER LOBELIA or GLADIOLE (L. Dortmanna). The slender, hollow, smooth stem rises from a submerged tuft of round, hollow, fleshy leaves longitudinally divided by a partition, and bears at the top a scattered array of pale-blue flowers from August to September.
INDIAN or WILD TOBACCO; GAG-ROOT; ASTHMA-WEED; BLADDER-POD LOBELIA (Lobelia inflata) Bellflower family
Flowers - Pale blue or violet, small, borne at short intervals in spike-like leafy racemes. Calyx 5-parted, its awl-shaped lobes 1/4 in. long, or as long as the tubular, 2-lipped, 5-cleft, corolla that opens to base of tube on upper side. Stamens, 5 united by their hairy anthers into a ring around the 2-lobed style. Stem: From 1 to 3 feet high, hairy, very acrid, much branched, leafy. Leaves: Alternate, oblong or ovate, toothed, the upper ones acute, seated on stem; lower ones obtuse, petioled, to 2 1/2 in. long. Fruit: A much inflated, rounded, ribbed, many seeded capsule. Preferred Habitat - Dry fields and thickets; poor soil. Flowering Season - July-November. Distribution - Labrador westward to the Missouri River, south to Arkansas and Georgia.
The most stupid of the lower animals knows enough to let this poisonous, acrid plant alone; but not so man, who formerly made a quack medicine from it in the days when a drug that set one's internal organism on fire was supposed to be especially beneficial. One taste of the plant gives a realizing sense of its value as an emetic. How the red man enjoyed smoking and chewing the bitter leaves, except for the drowsiness that
