 rather plicate, smooth beneath, but pilose in the axis of the veins. Calyx 

 campanulate, obtusely 5-toothed, about the length of the pedicel. Stamens 

 rather longer than the corolla. Superior petal veined. (Don's Mill.) A 

 deciduous tree. North America. Height 20 ft. to 30 ft. Introduced in 

 1823. Flowers yellow and red ; May and June, a week earlier than P. 

 flava. Fruit brown ; ripe in October. Leaves with rufous down on the 

 veins on the upper side. Flowers pale yellow, veined with red, disposed in

A tree resembling Pav^a flava but smaller. The plant in the Hort. Soc. 

 Garden was purchased from M. Catros of Bordeaux, under the name of JE. 

 ohioensis. In the Bot Reg. it is said to be most nearly related to JE. (Pavia) 

 flava, but to differ from it in the flowers appearing a week or 10 days earlier, 

 and in the leaflets being more glabrous, with rufous down on the veins on the 

 upper side, and with hairs in the axils of the veins on the under surface.
