Botanic Garden, 10 years planted, it is 16 ft. high. In Cassel, at Wilhelmshoe, 40 years planted, itis only 5 ft. high, with a trunk 8 in. diameter, the shoots being killed back every year by the autumnalfrosts. In Austria , at Vienna , in the University Botanic Garden, 26 years planted, it is 40 ft. high,the diameter of the trunk 18in., and that of the head 24ft.; at Laxenburg , 20 years planted, it is18 ft. high, the diameter of the trunk 6 in., and of the head 10 ft.; at Kopenzel, 25 years planted,it is 24 ft. high, the diameter of the trunk 2 in., and of the head 8 ft., against a wall ; at Briick onthe Leytha, 40 years planted, it is 34 ft. high, the diameter of the trunk If ft., and of the head24 ft. In Prussia, at Sans Souci, 20 years planted, it is 11 ft. high, the diameter of the trunk 4 in.;in the Pfauen-Insel, 9 years planted, it is 10 ft. high.

Cat&lpa syring&Jblia in Russia . At Petersburg and Moscow , it is a green-house plant; in theGovernment Garden at Odessa, in the Crimea , it forms a splendid tree, flowering every year, andsometimes ripening seeds ; though in the winter of 1835, M. Descemet informs us, it was very muchinjured by frost.

Catdlpa syring sefdlia in Italy . In various parts of Italy and the south of France , and particu-larly in the neighbourhood of Milan and Montpelier, the Catdlpa is planted as a road-side tree, andalong the avenues to country houses; where, with A/elia Azedardch and the tulip tree, and insome places, where the soil is moist, with MagnbkVz acumin&ta and other species, it forms a sceneof splendour and beauty worthy of a climate so congenial to vegetation. In Lombardy , at Monza ,29 years planted, it is 24ft. high ; the diameter of the trunk loin., and that of the head 24 ft.

App. I. Of the half hardy ligneous Plants of the OrderBignomkcese,

Eccremocdrpus longijibrus Humb. et Bonp. PI. TEquin., 1. p. 229. t. 65., and our fig. 1095., is aclimber, a native of Peru , with leaves abruptly tripinnate; and yellow flowers, which are producedin July and August. It was introduced in 1825, and is sufFruticose rather than ligneous ; but, preservedin a pit during the winter, and turned out into light rich soil in May, and trained against a wallwith a southern aspect, it grows with extraordinary rapidity, flowers freely, and ripens seeds, fromwhich, or by cuttings, it is readily propagated.

E. viridis Ruiz et Pav., Don’s Mill., 4. p. 231., has green flowers and bipinnate leaves. It is anative of Peru , in woods ; but has not yet been introduced.

Calainpelis scolrra D. Don; Eccremocdrpus scaber Ruiz et Pav., Bot. Reg., t. 939.; and our figs. 1096.and 1097. Introduced from Chili in 1824. Leaves bipinnate, with the leaflets alternate, obliquely cor-date, ovate,, serrated or entire. The calyx is green ; the corolla scarlet, or of a deep orange red; and thecapsule large and muricated. Itrequires exactly the same treatment as Eccremocarpus ; and, whereyoungplants cannot be preserved through the winter in a pit or green-house, they may be raisedfrom seeds (which the plant ripens abundantly in the open air, in the neighbourhood of London ),early in spring, in a hot-bed, and shifted from smaller pots to larger ones, so as to be ready tobe turned out in the open ground about the end of May. In mild seasons, this species, andalso Eccremocarpus longiflbrus, live through the winter with very little protection, and shoot upagain in the spring. A plant of CalSmpelis scabra, in the Horticultural Society’s Garden, has stoodout against a wall in this way since 1830. Perhaps it may be objected to our introtlucing such plantsas Eccremocarpus and Cal&mpelis, that they are not truly ligneous; and that, north of London , theyrequire to be treated more as herbaceous summer climbers or conservatory plants, than as hardyligneous ones. We readily admit that such plants as these form, as it were, the boundary of theligneous kingdom; but still we think they are more woody than herbaceous, and that the same kindof garden culture which is applicable to ligneous plants is the best adapted for them. Besides, in thesouth ot England, the stems of the spfecies of both these genera assume a decidedly more ligneouscharacter than they doin the climate of London , and the plants endure in the open air, against a wall,tor several years.
