Catalpa x 4^9 



appears to have come from the former. As Sargent points out, C. bignonioides and 

 C. Kaempferi flower at the same time, whereas C. speciosa is two to three weeks 

 earlier than C. Kaempferi. Moreover, Penhallow, 1 by an examination of the wood of 

 the different species of Catalpa and of the hybrid, has shown conclusively that the 

 latter is a cross between C. bignonioides and C. Kaempferi, in which the characters 

 of the latter are dominant ; and that C. speciosa was in no way concerned in its pro- 

 duction. Penhallow adds, that some of the seedlings of the hybrid, but not all, 

 revert to C. Kaempferi. 



" Tas' Japan hybrid," as it is commonly called, was introduced into Kew 

 gardens in 1891, and flowered in 1900 and succeeding years, but has not produced 

 fruit. At Kew it shows no excessive vigour. 



C. japonica, Dode, in Bull. Soc. Dend. France, i. 200 (1907), said to have been 

 introduced from Japan in 1886 by Simon-Louis, is unknown to me; but from 

 the description appears to be another hybrid between C. bignonioides and C. 

 Kaempferi. (A. H.)

A tree, attaining in China 40 feet in height. Young branchlets glabrous, 

 covered with minute glands. Leaves with a disagreeable odour, variable in size and 

 shape, about 5 in. long and 4 in. wide, ovate or deltoid, cuneate or truncate at the 

 base, ending in a long slender acuminate apex; entire," or with two lateral long-pointed 

 lobes, or with several irregular acute teeth on each side ; upper surface dark green, 

 shining, glabrous ; lower surface pale green, glabrous ; petiole glabrous. 



Flowers, three to nine, in a loose corymb ; axis and pedicels glabrous or with a 

 few simple hairs ; calyx glabrous, green below, pink above ; corolla, \\ in. long, with 

 a wide campanulate tube, which is tinged with yellow along two projecting ridges 

 and is elsewhere spotted purple, and a white five-lobed limb, with numerous purple 

 dots, which give the whole flower a decidedly pinkish tint. Fruit, described as very 

 long and slender, 25 to 40 in. in length and \ in. in diameter. Seeds greyish 

 brown, % in. long, with narrow pointed wings, ending in pencil-like tufts of pale 

 yellow hairs. 



The foliage of this tree is very variable entire or two- to three-lobed leaves 

 occurring on old trees ; whilst those with a dentate margin are characteristic of
