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

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

 long slender pedicels, in 2-5-tlowered 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, 



on slender pedicels, in 1-3-fruited clusters, depressed-globose, very fragrant, bright 

 red, dotted with pale spots, ^'-f in diameter; calyx prominent, with enlarged in- 

 curved mostly persistent lobes; flesh thick, juicy, subacid; nutlets 3-5, rounded at

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

 straight or divided close to the surface of the ground into several large upright 

 stems forming a round compact bushy head, and branchlets covered at first with 

 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 

 stout straight shining spines I'-l^ long. The fruit is gathered in large quantities and
