3. JASIONE L. Sp. Pl. 928. 1753. 
Herbs, the flowers in terminal heads subtended by a many-leaved involucre. Calyx-tube 
campanulate, adnate to the ovary, the limb 5-divided. Corolla at first tubular, splitting later 
to the base into 5 linear or linear-oblanceolate segments. Filaments subulate. Anthers united 
at the base, free above. Ovary inferior, 2-celled; stigma club-shaped. Capsule 2-celled, 
dehiscent by two terminal pores. [Greek name of some 
medicinal plant.] 
_Five species of central Europe and the Mediterranean Re- 
gion, the following typical.

Annual or biennial, with several stems from a simple 
root; stems 6~12’ high, branched above, leafy below, de- 
cumbent, erect or ascending, the branches spreading. 
Leaves linear, rough-hairy, sessile; flowers in long-pedun- 
a hemispherical heads; corolla blue, seldom white or 
pink. 
In waste places, Massachusetts to southern New York, Ad- 
ventive from Europe. June-Sept. 
Family 43. LOBELIACEAE Dumort. Comm. 
Bot. 57. 1822. 
LosEtia FaMILy. 
Herbs, or in tropical regions rarely shrubs or trees, often with milky sap which 
contains a narcotic-acid poison, with alternate, exstipulate, simple, entire, toothed 
or pinnately parted leaves and solitary, spicate, racemose or paniculate flowers. 
Calyx-tube adnate to the ovary, its limb 5-lobed or 5-parted, the lobes equal or 
unequal. Corolla gamopetalous, irregular, often bilabiate, its tube open on one 
side nearly or quite to the base, its limb 5-lobed ; stamens 5, inserted with the corolla ; 
filaments sometimes cohering into a tube; anthers united. Ovary 2~-5-celled; style 
single; stigma fringed; ovules numerous, sessile, horizontal, anatropous. Fruit 
a 1-5-celled capsule, or a berry. Seeds numerous, with a smooth or furrowed 
testa. Endosperm fleshy. 
About 20 genera and 600 species, of wide geographical distribution. 
1. LOBELIA L. Sp. Pl. 929. 1753. 
Herbs (some tropical species shrubs), with alternate or basal leaves and racemose spicate 
or paniculate, often leafy bracted, red, yellow, blue or white flowers. Calyx-tube turbinate, 
hemispheric or ovoid, adnate to the ovary. Corolla-tube straight, oblique or incurved, divided 
to the base on one side, 2-lipped in our species, the lobe on each side of the cleft erect or 
recurved, turned away from the other three which are somewhat united, the sinuses inclining 
to extend to the base of the corolla at maturity so as to divide it into 5 petals. Stamens free 
from the corolla-tube, monadelphous, at least above, two or all the 5 anthers with a tuft of 
hairs at the tips, three of them usually larger than the other two, all united into a tube or 
ring around the style. Ovary 2-celled, the 2 placentae many-ovuled; stigma 2-lobed or 2-cleft. 
Capsule loculicidally 2-valved. [Named after Matthias de L’Obel, 1538-1616, a Flemish 
botanist.]
