149 The Trees of Great Britain and Ireland 



branches ending in an inflorescence, and are normally developed on the ordinary 

 branches of young trees. As both forms occur on the same individual, var. hetero- 

 phylla, Meyer, cannot be maintained as a distinct variety. 1 In northern China, the 

 leaves are quite glabrous ; but in the mountains of central China, there are traces of 

 pubescence (simple hairs) on the upper surface of the leaves and on the petioles. 

 Specimens with more numerous flowers in the corymb, which has one or two of the 

 lateral axes branched, have been considered to be a distinct species, C. Duclouxii, 

 Dode ; but these are probably trees of greater vigour and not even a distinct 

 variety. 



C. Bungei is readily distinguishable by its glabrous shining leaves, with longer 

 and more slender points to the lobes than is the case in the other species. 



This tree is widely spread throughout the mountains of China, from Peking 

 in the north to Yunnan in the south-west, and is also recorded from the coast 

 provinces of Shantung and Chekiang. Wilson found it in Szechwan at 8850 feet 

 altitude, as a "tree 40 ft. in height, with white flowers suffused and spotted with 

 pink." In Hupeh, it grows at about 4000 to 5000 feet elevation in the mixed forests 

 of deciduous trees, and, my notes state, "40 feet high, 4 feet in girth, with pinkish 

 flowers, which, together with the leaves, are of a disagreeable odour." It is much 

 planted in temple grounds, at Peking, Shanghai, and elsewhere, and is usually known 

 as the ch'iu tree. 2 It flowers at Peking in May. 



This species is very rare in cultivation, the plants generally sold under this name 

 by nurserymen being either the dwarf form of C. bignonioides or C. Kaempferi. 

 Bureau knew of only one living specimen in France, a small tree at Segrez, which 

 had not produced flowers. 



It was introduced 3 about 1904 into the Arnold Arboretum by seed procured 

 from Peking ; and a tree sent by Sargent to Kew in 1905 is now about 8 feet high.

CATALPA FARGESI 



Catalpa Fargesi, Bureau, in Nouv. Archiv. Mus. Hist. Nat. vi. 195, pi. 3 (1894); Dode, in Bull. 



Soc. Dend. France, i. 204 (1907). 

 Catalpa vestita, Diels, in Engler, Jahrb. xxix. 577 (1900). 



A small tree, distinct from the other species, in the presence of stellate tomentum 

 or branched hairs on the young branchlets, leaves, axes of the inflorescence, pedicels, 

 bracts, and calyx. Leaves about 5 in. long and 4 in. broad, entire or with one or 

 two acute lateral lobes, subcordate at the base, acuminate at the apex ; tomentose on 

 the lower surface throughout, on the upper surface mainly on the nerves. 



1 Cf. Bretschneider, Bot. Sinicum, in Journ. N. China Branch, R. Asiat. Soc. xvi. 112 (1882), who states that "the 

 leaves on the same tree are very variable, cordate, entire, lobed, laciniate, triangular, sinuate, etc." 



* Bretschneider gives an account of the Chinese literature of this tree in Bot. Sin. ii. 339 (1882) and iii. 478 

 (1895). The classical name tze, with which he identifies the Catalpa, possibly indicated Sassafras Tzumu. Cf. vol. iii. 

 p. 515.
