Crataegus Rosaceae 549 



6-12-flowered, more or less villous corymbs ; calyx lobes lanceolate, usually 

 glandular-serrate ; stamens 5-10 ; anthers pink or red ; fruit oblong, slightly 

 pyriform or nearly globose, 10-14 mm thick, 10-16 mm long, glabrous, 

 bright crimson or scarlet at maturity, with soft, mellow flesh ; nutlets 3-5. 



A tree 6-8 m high, or often a stout arborescent shrub, with gray, slightly 

 scaly bark, and numerous ascending or spreading branches, forming a 

 conical or round crown ; branchlets rather stout, often flexuous, and armed 

 with numerous stout thorns. 



Uncommon in Indiana and found in thickets, pastures, and borders of 

 woods. Indiana specimens are mostly from high, wooded banks of streams.

20a. Crataegus pedicellata var. albicans (Ashe) Palmer. (Dole. Flora 

 of Vermont, 154. 1937.) (Crataegus albicans Ashe and Crataegus cristata 

 Ashe.) Differs from the typical form in the glabrous corymbs and petioles 

 and in the generally broader leaves. 



Known in Indiana from La Porte, Steuben, and White Counties and 

 found in habitats similar to those of the species.

21. Crataegus Putnamiana Sarg. (Deam. Trees of Indiana, eel. 2. pi. 

 96. 1932.) (Crataegus coccinioides of Eggleston, not of Ashe.) Map 

 1121. Leaves ovate or, on shoots, deltoid in outline, acute or short- 

 acuminate at the apex, rounded, truncate or subcordate at the base, 4-8 

 cm long, 3-7 cm wide, sharply and unevenly serrate with spinulose teeth 

 nearly to the base, incised, and generally with 3-4 pairs of shallow, 

 lateral lobes, the lowest pair sometimes enlarged and triangular on shoots, 

 thin but firm at maturity, scabrate above when young, and permanently 

 pubescent at least on the veins beneath; petioles slender, a third to half 

 as long as the blades, slightly villous and usually with stalked or sessile 

 glands; flowers 18-22 mm in diameter, in simple or rarely branched, 

 slightly villous or glabrate corymbs; stamens about 20; anthers usually 

 pink, sometimes white; fruit subglobose or depressed-globose, full and 

 rounded, 12-17 mm in diameter, bright red, sometimes slightly pruinose, 

 with thick flesh, becoming mellow but firm; calyx broad and shallow, 

 slightly elevated; calyx lobes lanceolate, glandular-serrate, usually per- 

 sistent on the fruit; nutlets 4-5, usually 5. 



A tree up to 4-5 m high, or sometimes an arborescent shrub with gray, 

 slightly scaly bark, ascending or spreading branches, and stoutish, glabrous 

 branchlets usually sparingly armed with stout, purple thorns. 



This species has been confused with Crataegus coccinioides, which dif- 

 fers from it in its glabrous, broader leaves with crisped margins, its larger 

 flowers in glabrous corymbs, and in its larger, bright crimson, usually 

 angular fruit with a very large calyx. 



Indiana specimens are from the unglaciated area and are found in 

 Clark and Floyd Counties in the "knobs" in open woodland, and in Martin 

 County on a wooded slope.
