BIGNONIACEAE. — CATALPA 305 



even to go farther and consider C. Duclouxii 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 Nouv. Arch. Mus. Paris, s6t. 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; 

 tree 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 shghtly pubescent on the under 

 side of the leaves and forms a transition to the preceding species. A closely related 

 Bpecies 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.
