The native habitat of C. ovata is apparently central China, where Wilson found 

 it common in the margins of woods and more especially in the open country of 

 Hupeh. Until recently it was generally considered a native of Japan, where it was 

 first discovered by Kaempfer and whence it was introduced into Europe in 1849, 

 but we know now that it was brought about the beginning of the Christian era by 

 priests of Buddha from China to Japan and there much planted around temples (c/. 

 Sargent, Silva N. Am. VI. 84). I am not able to find any reUable character to 

 distinguish C. Henryi Dode from the cultivated form of C. ovata.

 Catalpa sutchuenensis Dode I. c. 204, fig. 



Western Szech'uan: Ching-chi Hsien, alt. 1000 m., May 1907 

 (No. 640, in part; tree 12-16 m., flowers very light purple with yellow 

 throat); without locality, alt. 900 m., May 1904 (Veitch Exped. 

 No. 4289; tree 8-13 m., flowers white suffused and spotted with pink). 

 Eastern Szech'uan: South Wushan, June 1900 (Veitch Exped. No. 

 976; tree 7-16 m.). Western Hupeh: Fang Hsien, open country, 

 alt. 1200-1400 m., May 24 and October 1907 (No. 640 in part; tree 

 18-16 m., circumference 0.60-1.60 m., flowers rose-pink with orange 

 markings in throat); without locality, A. Henry. 



Catalpa Duclouxii, originally based on specimens from Yunnan, and C. sutchuenen- 

 sis are considered by Dode as two distinct species, the first characterized by a corym- 

 bose inflorescence and grouped therefore with C. ovata D. Don, and the second by a 

 racemose inflorescence and grouped with C. Bungei C. A. Meyer. There are, 

 however, no other differences between these two supposed species; the leaves and 

 also the flowers are exactly aUke and the infloresences differ only in this, that in C. 

 sutchuenensis the branches of the 2-6-flowered inflorescences are all simple, while 

 in C. Duclouxii the lower branches of the 6-16-flowered inflorescences bear 2 or 3 

 flowers, but one kind of inflorescence merges gradually into the other. No. 640 

 from Ching-chi Hsien and No. 4289 have the many-flowered inflorescence of typi- 

 cal C. Duclouxii, while No. 640 from Fang Hsien have all the lateral axes of the 

 inflorescence simple; the other numbers are more or less intermediate. It is possible
