 of older stems exhibiting a medullary cross : leaves of a single pair of ovate or oblong 

 acuminate and subcordiite entire leaflets and a compound tendril ; accessory leaves or

 several by monographers, but retained nearly intact by Benth. & Hook. Gen. ii. 

 1044, digitate species excluded) of several species, widely dispersed; ours impari- 

 pinnate and the leaflets serrate, ovate, and acuminate. They have been referred 

 to different genera or subgenera on account mainly of the number of ranks of 

 seeds. Fl. summer.

 corolla tubular-funnelform, orange and scarlet, 2 J or 3 inches long : stamens not exserted : 

 capsule lanceolate, slightly stipitate; valves very convex, acutely narrowly margined: 

 seeds several-ranked. — DC. Prodr. ix. 22:3 ; Nutt. Sylv. iii. t. 104 ; Bureau, Jlon. Bign.

 soil, Penn. and Illinois to Florida and Texas : common in cultivation. 



■ T. stans, Juss. Erect shrub: leaflets 5 to 11, narrower or lanceolate, more incisely 

 serrate : flowers racemose or paniculate : calj'X small ; corolla more campanulate, yellow, 

 inch and a half long : fifth stamen often with abortive anther : capsule linear, elongated, 

 sessile; valves carinate-convex : seeds single ranked. — Hook. Bot. Mag. t. 3101; DC. I.e.

 to Arizona. (W. Ind., Mex., &c.) 



3. CATALPA, Scop., Walt. (Aboriginal name.) — There are a N. China 

 and a Jajianese species allied to our own, and a' few somewhat anomalous West 

 Indian species. Fl. summer; showy. 



'C. bignonioides, Walt. Low or large tree, with spreading branches: leaves pubes- 

 cent, at least beneath, ample, cordate, acuminate, rarely somewhat angulate-lobed, long- 

 petioled : panicle large and loose, compound : lips of the calyx obovate, mucronate : 

 corolla inch long and broad, white or nearly so, dotted with purple and yellow in the 

 throat: pendulous slender capsules, a foot long. — Cav. 64; DC. 1. c. 226; Bureau, Mon.
