PLATE 31. Catalpa speciosa Ward. Seeds, natural size. 



an inch long, often marked externally with purple spots near the base, and 

 internally on the lower side with two bands of yellow blotches which fol- 

 low two parallel lateral ridges, and with occasional purple spots spreading 

 over the lobes of the lower lips of the limb, which, when the flower is 

 fully opened, has a vertical diameter of nearly two inches and a horizontal 

 diameter of two and a half inches. The filaments, which are marked near 

 the base with a few oblong purple spots, are slightly exserted, and rather 

 longer than the slender glabrous style. The fruit is eight to twenty 

 inches long and one-half to three-quarters of an inch in the middle, with 

 a thick wall, which towards spring splits into two concave valves; the 

 partition is thickened in the middle and nearly triangular in section. The 

 seed is an inch long and a third of an inch broad, with a light brown coat, 

 and wings which are rounded at the ends and terminate in a fringe of 

 rather short hairs.
