TREES OF NORTH AMERICA 



glandular-serrate; stamens 10; anthers large, pnrple; styles 3-5, surrounded at the 

 base by a narrow ring of pale hairs. Fruit ripening at the end of September and 

 soon falling, on short pedicels, in erect few-fruited clusters, subglobose and often a 

 little broader than long, red or greenish yellow, with a rosy cheek, about ^' in diam- 

 eter; calyx little enlarged, with spreading lobes usually deciduous before the fruit 

 ripens; flesh thin, yellow, dry and mealy; nutlets 3-5, thick, prominently ridged ^ 

 and grooved on the back, with a high broad ridge, about \' long. " 



A tree, sometimes 30 high, with a tall straight trunk G'-8' in diameter, covered 

 with close or slightly fissured bark broken into small gray or red-brown scales, and 

 often armed with long stout branched gray spines, ascending or spreading branches 1 

 forming a narrow irregular or round-topped head, and slender branchlets dark green 

 tinged with red and covered with long pale scattered white hairs when they first 

 appear, soon becoming glabrous, bright red-brown during their first year, and ulti- 

 mately ashy gray, with few or many thin straight or somewhat curved bright chest- 

 nut-brown spines 1^' to nearly 2' long; or in the dry soil of upland forests usually a 

 shrub, with numerous stems. 



Distribution. Low moist flat woods; northern Alabama and northwestern and 

 central Georgia, and occasionally on the drier uplands of the surrounding country; 

 common. 



**Stamens usually 20. 



52. Crataegus lucorum, Sarg. 



Leaves broad-ovate to obovate or rarely oval, broadly cuneate or full and rounded 

 at the entire base, coarsely serrate above, with straight teeth tipped with large per- 

 sistent bright red finally dark glands, and deeply divided above the middle into 3 or 4 

 pairs of wide acute or acuminate lobes, rather more than a third grown when the 

 flowers open early in May and then light yellow-bronze color, covered on the upper 

 surface with short soft pale hairs and glabrous on the lower surface, and at maturity 



membranaceous, smooth, dark dull green and glabrous above, pale yellow-green 

 below, about 2' long and 1^' wide, with slender yellow midribs and 3 or 4 pairs of 

 thin primary veins extending obliquely to the points of the lobes; their petioles slen- 

 der, glandular, often somewhat winged toward the apex, I'-l^' long; on vigorous
