Orver CXXXIV. LOBELIA‘CE& (this order contains plants 
agreeing with the genus Lobélia in many characters). Juss. ann.

Calyx superior, 5-toothed, or 5-parted, seldom entire, with the 
tube adnate to the ovarium at the base. Corolla monopetalous, 
irregular, inserted in the calyx, 5-lobed, or deeply 5-cleft. Sta- 
mens 5, inserted into the calyx alternately with the lobes of the 
corollas; anthers cohering ; pollen oval. Ovarium inferior, with 
from 1 to 3 cells, but usually of 2 cells. Ovula very numerous, 
attached to the axis or parietes of the fruit. Style simple; stigma 
usually 2-lobed, surrounded by a cup-like fringe. Fruit cap- 
sular or baccate, 1-2-celled, rarely 3-celled, many seeded, de- 
hiscing at the apex. Seeds attached to the axis or parietes 
of the fruit. Embryo straight, in the axis of fleshy albumen, 
with the radicle pointing to the hylum.—Herbaceous plants or 
shrubs. Leaves alternate, exstipulate. Flowers axillary or 
terminal, of various colours. 
This order appears more nearly related to Compésite than to 
Campanulacee, in their cohering anthers, and in the irregularity 
of the corolla; the stigma is surrounded by hairs, which are 
probably analogous to the indusium of Goodendvie, to which 
order Lobeliàceæ approaches very closely. It participates in all 
the affinities of Campanulacee. 
‘ The plants contained in this order are all dangerous or sus- 
Picious, in consequence of the acridity of their milk. Tapa 
Feuillei yields a dangerous poison in Chili. The most active 
article of the Materia Medica of North America is said to be 
Lobelia inflata; it is possessed of an emetic, sudorific, and 
powerful expectorant effect, especially the first. When given 
with a view to empty the stomach, it operates vehemently and 
speedily, producing, however, great relaxation, debility, and per- 
Spiration, and even death, if given in over-doses. Barton, I. p. 
189. The antisyphilitic virtues ascribed to Lobelia syphilitica 
are supposed to have resided in its diuretic properties; they 
are, however, generally discredited altogether. Barton, 2. p. 
211. Hippobréma longiflora, a native of some of the West India 
Islands, is one of the most venomous of plants. The Spanish 
Americans call it Rebentia Cavallos, because it proves fatal to 
horses that eat it; it acts as a violent cathartic, the effects of 
which no remedy can assuage, and which ends in death. The 
leaves are an active vesicatory. Lobélia cardinalis is an acrid 
plant, which is reckoned anthelmintic. Barton, 2. p- 180. All 
the plants contained in this order are very ornamental, and

therefore well deserving the care of the gardener. The flowers 
are very showy blue, white, red, scarlet, but seldom yellow. 
Synopsis of the genera. 
1 Crerméntea. Calyx tubular, 5-cleft. Corolla arched, 5- 
cleft, almost regular. Stamens with combined filaments and 
cohering anthers; the two lower anthers bearded. Stigma 
2-lobed, girded by hairs. Capsule baccate, naked at the apex, 
indehiscent, 2-celled, many-seeded. 
2 Rotra'npia. Calyx 5-parted. Corolla compressed at the 
sides, with an undivided tube, and a 5-parted, somewhat bila- 
biate limb. Stamineous column adnate to the superior part of 
the corolla. Anthers cohering, two lower ones bearded. Stigma 
pilose. Capsule baccate, crowned by the calyx, 2-celled, many- 
seeded, indehiscent. 
3 Cya'nea, Calyx 10-furrowed, with oblong, foliaceous, 
curled segments. Corolla tubular, arched, with a 5-parted, 
somewhat bilabiate limb. Stamens, combined filaments, and 
cohering bearded anthers. Stigma capitate ciliated. Capsule 
baccate, 10-furrowed, indehiscent, crowned by the limb of the 
calyx, 2-celled, many-seeded. 
4 Detissea. Limb of calyx 5-toothed. Corolla with an 
arched undivided tube, and a 5-parted somewhat bilabiate 
limb. Anthers cohering; 2 lower ones bearded. Stigma 2- 
lobed, girded by hairs. Capsule baccate, crowned by the limb 
of the calyx, indehiscent, 2-celled, many-seeded. 
5 Pra‘tra. Limb of calyx 5-toothed (f. 119. a.). 
cleft on the back, even to the base, and therefore the limb is 
5-parted, unilabiate, or all on the lower side (f. 119, b.). 
Stamens combined above and the anthers cokering; the two 
lower anthers mucronate (f. 119. d.). Stigma 2-lobed. Cap- 
sule baccate, crowned. 
6 Tu'ra. Calyx spherical, 5-parted. Corolla cleft on the 
back almost to the base, having the limb divided into 5 segments, 
which are all united at their tips. Stamens combined almost to 
the base; anthers cohering, bearded. Stigma 2-lobed, protrud- 
ing. Capsule 2-celled, many-seeded. 
7 Sipnoca’meytus. Limb of calyx 5-parted (f. 120. d.). 
Corolla with a curved undivided tube, which is ventricose in 
the middle, and a 5-parted bilabiate limb (f. 120. b.). Stamens 
and anthers combined; anthers bearded. Capsule 2-celled, 2- 
valved, dehiscent. 
8 Losera. Limb of calyx 5-parted (f. 121. a.). Corolla 
with the tube cleft on the upper side, and thickened at the base, 
and a bilabiate limb (f. 121. g.). Anthers cohering ; 2 lower 
ones usually bearded. Capsule 2-celled, 2-valved, dehiscent at 
Corolla 
the apex. 
9 Dorrma’nna, Limb of calyx 5-parted. Corolla with 
the tube cleft on the upper side, a bilabiate limb, and a bearded 
throat. Stamens with free filaments, and cohering bearded an- 
thers. Stigma capitate, hairy. Capsule half superior, 3-celled, 
3-valved, dehiscent, many-seeded, surrounded by the calycine 
segments below the apex.
