Crataegus pruinosa (Wendl.) K.Koch 



An irregularly branched shrub, 1-4 m high, with gray or brown gray 

 bark, scaly on old stems ; the branchlets slender, usually armed with many 

 long, slender 'thorns. 



Scattered and uncommon in southern Indiana, usually growing on bluffs 

 or rocky or sandy banks of streams.

13. Crataegus biltmoreana Beadle. (Crataegus intricata of Eggleston, 

 not Lange, in Britton and Brown, Illus. Flora, ed. 2. fig. 2366, Crataegus 

 modesta Sarg., and Crataegus villicarpa Sarg.) Map 1113. Leaves ovate- 

 elliptic or nearly orbicular, mostly 3-8 cm long and 2.5-6 cm wide, abruptly 

 or acutely pointed at the apex, abruptly cuneate or rounded at the base, 

 and usually slightly decurrent on slender (1-3 cm long), glandular petioles, 

 coarsely serrate nearly to the base, the lower teeth glandular or gland- 

 tipped, usually incised with 1-3 pairs of short, triangular lobes, thin, dull 

 yellowish green, short-villous or scabrate above and pubescent at least on 

 the veins beneath ; flowers 18-22 mm in diameter, in compact, nearly simple, 

 3-7-flowered, villous corymbs; stamens about 10; anthers pale yellow; 

 calyx lobes villous, conspicuously glandular-serrate or pectinate; fruit 

 subglobose or slightly attenuate at the base, 10-15 mm in diameter, with 

 a large, shallow calyx, pubescent, bronze green or orange red, more or 

 less blotched with russet or brown ; nutlets 3-5. 



A stout shrub 1-4 m high, with brownish gray, scaly bark, ascending or 

 spreading branches, and stout branchlets at first villous but soon becoming 

 glabrous, olive green or brown the first season, later becoming gray and 

 usually abundantly armed with long, slender thorns. 



This has been confused with Cratageus intricata Lange, but examina- 

 tion of specimens from the type tree of that species, cultivated in the 

 Botanic Garden at Copenhagen, Denmark, and sent us by A. Lange, shows 

 it to be the much commoner glabrous plant described under number 11. 



Rare in Indiana and known only from Lawrence and Vermillion Coun- 

 ties.
