i486 The Trees of Great Britain and Ireland 



have originated in the United States, and is possibly a hybrid. It is cultivated by 

 Simon-Louis at Metz. 



3'. Var. variegata, Bureau, op. cit. 183. 



Variegated with white or yellow. In var. Koehnei, Dode, op. cit. 206, the leaves 

 are pale yellow, with irregular angular green patches. Cultivated by Simon- Louis. 



4. Var. erubescens, Nicholson, in Woods and Forests, 1885, p. 52. 

 Catalpa erubescens, Carrifcre, in Rev. Hort. 1. 460 (1869). 



This form, which I have not seen, is said to have purplish petioles and glandular 

 spots, with a more compact inflorescence, and a more highly coloured corolla with a 

 less deeply divided limb than the type. It is possibly, as Dode suggests, a hybrid. 



5. Var. nana, Bureau, op. cit. 183. 



A low spreading bush, with crowded branches, occasionally grafted high. The 

 leaves are identical in odour and in all other respects with C. bignonioides ; and there 

 are no grounds for supposing it to be a form of C. Bungei, under which name it is 

 commonly known in nurseries and gardens. It has not yet flowered anywhere, and 

 appears to have been first cultivated at Segrez 1 in 1877, where it may possibly have 

 arisen as a sport. 



C. bignonioides is a native of the eastern part of the United States ; but the 

 exact localities where it is truly native cannot be determined with certainty. It is 

 usually supposed to be indigenous on the banks of rivers in south-western Georgia, 

 western Florida, and central Albania and Mississippi, and to be naturalised through- 

 out the south Atlantic States. On account of its handsome flowers it was extensively 

 planted for ornament ; and its dissemination has been aided by its winged seeds, 

 which are borne to a considerable distance by the wind and float on water without 

 injury for a long period. As it bears moderately severe winters it may possibly have 

 been a native of the more northern parts of the Alleghany range, where it is not now 

 met with in the existing forests. It thrives as far north as Philadelphia, but is killed 

 during the winter at Rochester on Lake Ontario, and often succumbs at St. Louis. 2 



(A. H.) 



The first account of this species was published in The Natural History of 

 Carolina by Catesby, who introduced 3 it into England in 1726. 



The largest tree mentioned by Loudon was one at Syon, 52 ft. high and 3 ft. in 

 diameter, of which only the dead stump remains, but there is a spreading tree grown 

 from one of its layered branches on the north side of the lake which was in flower in 

 July 191 2 when I saw it last. A tree at Kew, which died in 1907, when it was about 

 sixty years old, was 30 ft. high and 6 ft. 1 in. in girth. A tree in the Terrace Gardens, 

 Richmond, was 35 ft. by 8 ft. 1 in. in 1912. A fine specimen 4 in Mr. Denne Dunn's 

 garden at Canterbury was 32 ft. high in 1876. At Caldrees, Ickleton, near Cambridge, 

 there is a fine tree, which flowers freely every year ; it is about 35 ft. high and 7 ft. 

 in girth.

 Rosslyn, Stamford Hill.
