sometimes unequally 3-lobed by deep narrow lateral sinuses. Flowers appearing 

 with the unfolding of the leaves in February and early March, 1' in diameter, on 

 long slender pedicels, in 2-5-flowered simple glabrous corymbs; calyx-tube broadly 

 obconic to subglobose, glabrous, the lobes nearly triangular, entire or minutely 

 glandular-serrate, often flushed with red toward the apex. Fruit ripening in May,

A tree, 20-30 high, with a trunk 12'-18' in diameter, sometimes tall and

 rufous or occasionally pale hairs, becoming at the end of their first season glabrous, 

 lustrous, bright red or sometimes light brown, and often unarmed or armed with
