Crataegus incaedua Sara. 



pink or red ; fruit subglobose, 9-12 mm in diameter, bright red and suc- 

 culent at maturity; calyx slightly elevated; calyx lobes glandular-serrate, 

 reflexed in fruit ; nutlets 2-3, deeply pitted on the ventral surfaces. 



A stout shrub or rarely a small tree up to 6-8 m high, with dark gray, 

 scaly bark and stout ascending or slightly spreading branches; branchlets 

 glabrous or slightly villous when young, becoming light brown or chestnut- 

 colored at the end of the first season and finally gray, rather stout and 

 armed with numerous long (5-9 cm), curved thorns. 



Infrequent but generally distributed in Indiana, growing in thickets or on 

 banks or bluffs of streams.

 Leaves ovate or elliptic, mostly 3-7 cm long, and 2-5 cm wide, obtuse, 

 acute or short-acuminate at the apex, cuneate at the base and tapering 

 into short (0.3-1 cm) petioles, coarsely serrate except near the base, un- 

 divided except rarely on shoots, firm to subcoriaceous and with veins 

 slightly impressed above at maturity, dark green and scabrate above when 

 young, paler and pubescent beneath; flowers 15-18 mm in diameter, usually 

 8-20, in lax, compound, villous corymbs; stamens usually 10-15; anthers 

 pale yellow ; fruit subglobose or oblong, 8-12 mm in diameter, red at matur- 

 ity, sometimes slightly glaucous; calyx lobes serrate or glandular-serrate, 

 reflexed; nutlets 2-3, usually 2, sometimes with shallow pits on the 

 ventral surfaces. 



A tree up to 6-7 m high, with pale brown gray bark and ascending or 

 spreading branches, forming a low, conical crown ; branchlets villous the 

 first season, becoming gray, usually armed with numerous, long, curved 

 thorns. 



Crataegus incaedua is probably a hybrid between Crataegus Calpoden- 

 dron and Crataegus crus-galli or some species of the Crus-galli group. 



Known in Indiana only from Harrison County, where it was found along
