BIGNONIACEAE. — CATALPA 305 
even to go farther and consider C. Duclouzii only a glabrous variety of C. Fargesii 
Bureau, which agrees with it in almost every character except in the pubescence 
and perhaps in the somewhat stouter capsules. 
A photograph of this tree will be found under No. 0192 of Wilson's photographs. 
Catalpa Fargesii Bureau in Now. Arch. Mus. Paris, sér. 2, VII. 
195, t. 3 (1894). 
Western Hupeh: Fang Hsien, open country, alt. 1000-1300 m., 
May 25, June and November 1907 (No. 636; tree 6-22 m., circum- 
ference 1-1.60 m., flowers rosy-purple); Hsing-shan Hsien, rare, alt. 
1300 m., June 1907 (No. 748; tree 7-13 m., circumference .60-1.60 m., 
flowers bright rosy-purple); same locality, June 7, 1910 (No. 4556; 
iree 17-20 m., flowers rosy-pink). Szech'uan: without locality, 
A. Henry (No. 5856’). 
Catalpa Fargesii shows considerable variation in the density of its pubescence; 
while No. 748 has the lower surface of the leaves densely yellowish tomentose, 
No. 636 is only pubescent and No. 5856* is only slightly pubescent on the under 
side of the leaves and forms a transition to the preceding species. A closely related 
Species or possibly only a variety is C. vestita Diels, which differs in its smaller 
flowers and smaller leaves whitish tomentose beneath. Seeds of this species col- 
lected by Wilson have been distributed erroneously under the name of C. vestita, 
while those of C. Duclouxii have been sent out as C. Fargesii.
