BIGNONIACEJE. XVIII. INCARVILLEA. XIX. WIGHTIA. XX. CATALPA. 



XVIII. INCARVI'LLEA (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.) 

 Juss. gen. 138. ed. Usteri, p. 154. Lam. diet. 3. p. 233. ill. t. 

 527. Bunge, in mem. acad. petersb. 2. p. 120. 



LIN. SYST. Didynamia, Angiosperma. 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, 1. 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 Catdlpa, or 

 Fee num. Grcecum. The rudiment of a sterile filament not seen, 

 ex Juss. 1. c. 



1 I. SINE'NSIS (Lam. diet. 3. p. 233.) "11. G. Native of 

 China, on way sides, near Pekin, and from that to the north, 

 even to the limits of the empire. J. Chinensis, Bunge, mem. 

 acad. petersb. 2. p. 120. Campsis adrepens, 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, 1. c. Stem branched, 

 striated, a foot high. Leaves like those of Chelidbnium hy'bridum, 

 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. PI. 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. 



XIX. WI'GHTIA (named after Richard Wight, F.L.S. of 

 the East India Company's Medical Service ; lately in charge of 

 the botanical establishment at Madras.) Wall. pi. rar. asiat. 1. 

 p. 71. t. 81. 



LIN. SYST. Didynamia, Angiosperma. 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.

 on Sheopore and Sumbunah. Flowers rose-coloured, scent- 

 less, an inch long.

LIN. SYST. Diandria, Monogy'nia. Calyx 2-parted. Co- 

 rolla campanulate, with a ventricose tube, and an unequal, 4- 

 lobed limb. Stamens 5, 2 of which are fertile, and the other 3 

 sterile. Stigma bilamellate. Capsule silique-formed, long, cy- 

 lindrical, 2-valved ; dissepiment opposite the valves. Seeds 

 membranously margined, and pappose at base and apex. 

 Trees with simple leaves, opposite, or disposed 3 in a whorl. 

 Flowers terminal, panicled. 



1 C. SYRINO^FOLIA (Sims, bot. mag. 1094.) leaves cordate, 

 flat, 3 in a whorl. T? . H. Native of North America, on the 

 banks of the Ohio, Mississippi, and Delaware, &c. in gravelly 

 soil ; it is found in considerable quantities in the forests of 

 Wabash, Illinois territory, where the wood is even split for pa- 

 lings. Schkuhr, handb. 1. 175. Bignonia Catalpa, Lin. spec. 868.

 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. 



Syringa-leaved Catalpa. Fl. July, Aug. Clt. 1726. Tree 

 20 to 40 feet.

 is the Japanese name of the tree. Thunberg remarks, that the 

 Japanese lay the leaves on parts of the body affected with pain, 

 supposing them to be beneficial to the nerves ; and that a decoc- 

 tion of the pods is esteemed serviceable in asthma.
