2. Catalpa ovata G. Don (Chinese catalpa)

Pl. 304 d; Map 1283

Plants eventually becoming trees to 15 m tall, but already flowering when still a shrub 1 m tall. Bark gray to grayish brown, divided into shallow furrows and thin plates on older trunks. Leaf blades 8–25 cm long, entire or more commonly shallowly 3-lobed or 3-angled toward the middle, noticeably tapered at the tip, the surfaces glabrous or minutely pubescent with short, straight hairs along the veins when young and then becoming glabrous or nearly so at maturity. Calyces 6–9 mm long. Corollas 2.0–2.5 cm long, light yellow, the middle lobe of the lower lip not notched. Fruits 20–35 cm long, 0.5–0.7 cm in diameter, relatively thin-walled, the valves becoming flattened after dehiscence. Seeds with the body 6–8 mm long, 2.5–4.5 mm wide, the hairs of the tufts more or less parallel. 2n=40. May–June.

Introduced, known thus far only from Boone and Crawford Counties (native of China; introduced sporadically in the eastern U.S.). Roadsides and open, disturbed areas.

This species is far less commonly cultivated in the United States than are the two North American species. As in C. bignonioides, the leaves have a strong unpleasant odor when crushed or bruised.
