XVIII. INCARVILLEA (named after P. Incarville, a 
Chinese Jesuit, who first sent specimens of it to Bernard de 
Jussieu, in the year 1743; and seeds of many other plants, as, 
for instance, the Chinese Aster, so common in our gardens.)

Lis. syst. Didyndmia, Angiospérma. Calyx tribracteate, 
pentagonal, 10-cleft ; the 5 outer segments subulate, elon- 
gated, and glabrous, thickened; the inner ones shorter and 
bifid. Corolla bilabiate; segments nearly equal. Stamens 4, 
didynamous ; filaments glandularly thickened at apex ; anthers 
bisetose, 2-celled ; cells horizontal, opposite, dehiscing at bottom. 
Stigma bilamellate. Capsule silique-formed, 6-ribbed, falcate, 
dehiscing laterally ; dissepiment bilamellate, contrary to the 
fissures. Seeds numerous, winged, Bunge,l. c. Calyx 5-cleft, 
tribracteate. Corolla with a tubular base, a ventricose throat, 
and an unequal, 5-lobed limb. Stamens didynamous; anthers 
2-lobed. Stigma bilamellate. Capsule silique-formed, com- 
pressed, long, narrow, 2-celled, 2-valved ; dissepiment opposite 
the valves, many-seeded. Seeds winged.—A Chinese herb; 
with alternate, striated branches; alternate, pinnately jagged 
leaves; and loose, spicate racemes of flowers. Corolla like 
that of Digitalis; and the capsule like that of Catálpa, or 
Fe num Gre cum. The rudiment of a sterile filament not seen, 
ex Juss. l. c. 
1 I. Sixz'ssis (Lam. dict. 3. p. 233.) X. G. Native of 
China, on way sides, near Pekin, and from that to the north. 
even to the limits of the empire. J. Chinénsis, Bunge, mem. 
acad. petersb. 2. p. 120. Campsis adrépens, Lour. coch. 378. 
Stem 1-2 feet high, herbaceous, erect. Leaves bipinnatifid ; 
leaflets cut; lobes linear. Racemes terminal, loose. Flowers 
nearly sessile. Corollas large, scarlet, deciduous. Capsule 
2 inches long and more. The figure of Lam. expresses the 
upper part of the plant well, ex Bunge, l. c. Stem branched, 
striated, a foot high. Leaves like those of Chelidónium hybridum, 
pinnately jagged, petiolate, glabrous. Flowers like those of 
Digitalis, loosely spiked, terminal, purple, ex Willd. spec. 3. p. 
289. The plant of Jussieu is probably distinct from that of 
Bunge. 
China Incarvillea. Pl. 1 to 2 feet. 
Cult. "This is a most elegant plant when in blossom. Should 
it ever be introduced to our gardens, we would recommend its 
being treated as a greenhouse plant. A mixture of loam, peat, 
and sand, or any light rich soil, will suit it ; and cuttings will 
probably be easily rooted.

the East India Company's Medical Service; lately in charge of 
the botanical establishment at Madras.) Wall. pl. rar. asiat. 1. 
B 7E csl. 
Lin. syst. — Didynàmia, Angiospérma. Calyx 4-toothed. 
Corolla funnel-shaped; limb 4-cleft; upper segment 2-lobed. 
Stamens 4, didynamous, without any hypogynous disk, or sterile 
filament. Stigma clavate, undivided. Capsule follicular, 2- 
valved; dissepiment parallel with the valves, placentiferous on 
both sides, at length free. Seeds imbricated lengthwise, winged 
at both ends. Radicle inferior.—A large, twining shrub. 
Leaves opposite, simple, and are, as well as the peduncles, 
covered with minute, stellate, deciduous down. Racemes large, 
axillary; peduncles dichotomous. This genus differs from all 
other Bignoniaceous plants, in the complete absence of a hypo- 
gynous disk, and sterile filament; and in the margins of the 
valves being bent inwards, so much so as to form the dissepi- 
ment ; in the seeds being erect; and in the radicle being in- 
ferior.

cliff. 317. Branches strong. Leaves large, deciduous. Pani- 
cles large, branchy, terminal. Corollas white, speckled with 
purple and. yellow. This tree has a good effect when it stands 
in the middle of large openings, where it can freely send forth its 
side branches, and show itself to advantage; but it always re- 
quires a sheltered situation. The leaves, however, come 
out very late. The branches dye wool a kind of cinnamon 
colour.  'This tree appears to have been introduced by the 
aborigines, hence its name of Catawba, derived from the Indians 
residing on Catawba river.
