cm long-. 4-6 cm wide, rounded, rarely truncate or acute at 

 base, acuminate at apex, 4-7 short very acute lobes beginning- 

 near the broad base; petiole stout, usually margined and 

 glandular, purplish, as is the midrib. Flowers, appearing 

 about the middle of May in many 6-20-flo\vered compound or 

 simple glabrous corymbs are about 15 mm wide; stamens 5-8, 

 anthers dark rose. Fruit, borne in small simple or compound 

 clusters, ripening about the middle of September, is oblong, 

 12-14 mm long, 9-11 mm thick, scarlet frequently mottled 

 with green or russet at the apex; the linear subentire nearly

Crataegus multifida. A shrub 1-2 m in height, with 

 slender slightly zigzag red-brown glabrous twigs, sparingly 

 armed with 4-7 cm-long thorns. The leaves are thin, firm, 

 bright green, soon glabrous, broadly ovate in outline, the 

 blades 4-5.5 cm wide, acuminate at apex, round or cordate, 

 seldom obtuse at the broad hase. 3-5 pairs of deep acuminate 

 lobes, the lower pair spreading and with reflexed tips, sharply 

 serrate or doubly serrate. Flowers, appearing the last week 

 in May in rather small compact slightly compound glabrous 

 corymbs, are about 15 mm wide; stamens usually 10. Fruit. 

 borne in small compact compound drooping clusters, ripening 

 late in September and falling with and after the leaves, is 

 oblong. 11-14 mm long. 9-11 mm thick, rounded at the ends, 

 crimson, capped by the closely sessile appressed, narrowly 

 triangular usually entire lobes; flesh yellow, soft and pulpy, 

 seed 4-5 mm, 6-7 mm long.
