BIGNONIACEAE 1095 
1. Stenolobium stáns ( L.) D. Don. A branching plant 3-14 dm. tall, with erect 
stem, the foliage glabrous or minutely pubescent. Leaves pinnate, 1-2 dm. long: leaflets 
7-9 ; blades lanceolate, narrowly elliptic or nearly linear, 4-10 cm. long, acuminate, sharply 
serrate, sessile or nearly so: racemes rather many-flowered : pedicels variable, 1-10 mm. 
long: calyx tubular-campanulate, 3-5 mm. high ; lobes often triangular, acuminate, much 
shorter than the tube: corolla yellow, funnelform, 3.5-4.5 em. long ; limb 4-5 em. broad, 
the lobes undulate : capsules linear, 10-20 cm. long, acute. [Tecoma stans ( L.) Juss. ] 
In sandy soil, Florida and southern Texas to Mexico. Also in tropical America. 
3. CAMPSIS Lour. 
Vines. Leaves mainly opposite: blades unequally pinnate, the leaflets with toothed 
blades. Flowers in clusters or panicles. Calyx tubular-campanulate: lobes 5, nearly 
equal. Corolla tubular-funnelform. Stamens included. Ovary with numerous ovules 
borne in several rows in each cavity. Capsule narrow, with firm-leathery concave valves. 
Seeds winged. TRUMPET-FLOWER. TRUMPET-CREEPER. 
1. Campsis radicans (L.) Seem. A bushy vine climbing by aérial rootlets, the foliage 
softly pubescent to glabrate, the stems several m. long. Leaves pinnate: leaflets 7-11 ; 
blades oval, ovate or elliptic, 2-6 cm. long, acute or usually acuminate, coarsely serrate, 
gradually narrowed, short-petioluled : corymbs few-flowered: pedicels stout, 0.5-2 cm. 
long : calyx tubular-campanulate, 14-18 mm. long; lobes triangular or triangular-ovate, 
much shorter than the tube: corolla red and orange, or yellow within, tubular-funnel- 
form, 5-9 cm. long ; limb 3-5 em. broad, oblique, the lobes suborbicular or reniform : cap- 
sules spindle-shaped, 1-1.8 em. long, acute. [Tecoma radicans ( L.) DC.] 
In woods, swamps and thickets, Pennsylvania to Missouri, Florida and Texas. 
4. CATALPA L. 
Shrubs or trees, with a watery sap, scaly bark and soft wood. Leaves opposite, 
whorled or alternate, deciduous, without stipules : blades membranous. Flowers large and 
showy, white or yellow, in terminal panicles or corymbs. Calyx closed, obovoid and apic- 
ulate when young, later splitting into two broad concave lobes. Corolla oblique, strongly 
blotched or spotted, its limb bilabiate, the upper lip 2-lobed, the lower 3-lobed. Stamens 
2 or rarely 4, adnate to the base of the corolla, accompanied by several minute or rudimen- 
tary staminodia, included or slightly exserted : filaments filiform, flattened : anthers introrse, 
the sacs divergent, brought near the stigma by a bend in the filaments. Ovary 2-celled, 
sessile on a thick disk : style filiform: stigmas 2. Ovules numerous, inserted in many rows 
on the central placenta, horizontal, anatropous. Capsule much elongated, nearly 
terete, tapering at both ends, persistent, at length loculicidally 2-valved. Seeds nu- 
merous, in 2-4 ranks, flattened, much broader than long with a membranous testa which 
is constricted at either end of the seed and produced into long fimbriate wings at the 
sides. INDIAN BEAN. CIGAR-TREE. 
Panicles many-flowered, crowded: corolla with a limb 4-5 X 5-6 cm. 1. C. Catalpa. 
Panicles few-flowered, lax: corolla with a limb 6-7 x 7-8 em. 2. C. speciosa. 
1. Catalpa Catálpa (L.) Karst. A tree rarely 20 m. tall, with wide spreading 
branches. Leaf-blades ovate, 1-3 dm. long, acuminate, more or less densely tomentose be- 
neath, undulate, truncate or subcordate at the base; petioles usually shorter than the 
blades: panicles many-flowered: calyx glabrous or nearly so, 8-12 mm. long; lobes 
abruptly pointed: corolla white; tube campanulate, with 2 rows of yellow blotches within ; 
limb 4-5 X 5-6 em. the 3 lower lobes with purple spots: capsules linear, 1.5-4 dm. long, 
terete. [C. bignonioides Walt. ] 
In woods, mostly on river banks, New York to Florida and Texas. Native southward. Spring. 
2. Catalpa speciósa Warder. A tree sometimes 40 m. tall, with a thick scaly bark. 
Leaf-blades ovate or oblong-ovate, 1-3 dm. long, acuminate, undulate or angulately lobed, 
tomentose beneath, truncate or cordate at the base; petioles nearly as long as the blades 
or usually shorter: panicles few-flowered: pedicels 2-3 cm. long: calyx purple; lobes 
abruptly acuminate: corolla white; tube conic-campanulate, with 2 rows of yellow 
blotches within ; limb 6-7 X 7-8 em. ; lobes of the lower lip blotched with purple: capsules 
linear, 3.5-5 dm. long, terete. 
In damp soil or swamps, Illinois and Missouri to Alabama and Texas. Spring.
