tendrils. 
2. Catalpa. Pod terete: fertile stamens only 2: trees: leaves simple, mainly op- 
posite, ovate or cordate. 
3. Chilopsis. Pod terete: fertile stamens 4: shrub or tree: leaves simple, oftener 
alternate or scattered, linear. 
1. TECOMA Juss. (TRUMPET-FLOWER or TRUMPET-CREEPER. ) 
Erect shrub or woody climber, with compound leaves, bell-shaped 
5-toothed calyx, funnelform 5-lobed a little irregular corolla, 4 stamens, 
2-celled pod with the partition at right angles to the convex valves, and 
transversely winged seeds. 
1. T. radicans Juss. Climbing by aerial rootlets: leaves pinnate; leaflets 9 or 
11, ovate, pointed, toothed: flowers corymbed: stamens not protruded beyond the 
tubular funnelform orange and scarlet corolla (6.5 to 7.5 cm. long): pod oblanceo- 
late, 10 to 12.5 em. long.—Moist soil, extending from the Atlantic and Gulf States 
into Texas, and common in cultivation, 
2. T. stans Juss. Erect shrub: leaflets 5 to 11, narrower or lanceolate, more in- 
cisely serrate: flowers racemose or paniculate: corolla more campanulate, yellow, 
3.5 cm. long: fifth stamen often with abortive anther: pod linear, elongated, sessile.—

2. CATALPA Scop., Walt. (CaTaLpa. INDIAN BEAN.) 
Trees, with ovate or cordate and mainly opposite leaves, deeply
