at the base by a broad ring of long shining white hairs. Fruit ripening from the 

 middle to the end of August, on short stout pubescent pedicels, solitary or in 2 or 

 3-fruited drooping clusters, obovate to short-oblong, usually about ^' long, bright 

 orange-red, lustrous, marked by numerous pale dots; calyx prominent, with an elon- 

 gated tube puberulous on the outer surface, and reflexed glandular-serrate lobes; flesh 

 thin, yellow, dry and mealy; nutlets 4 or 5, acute at the base, full and rounded at the 

 apex, rounded and occasionally slightly ridged on the back, about ^' long. 



A tree, rarely more than 15 high, with a long straight trunk 6'-8' in diameter, 

 covered with thick nearly black deeply furrowed bark broken into short thick plate- 

 like scales, small drooping branches forming a handsome symmetrical head, and 

 slender conspicuously zigzag pendulous branchlets coated at first with long pale 



matted hairs, becoming during their first season dark red-brown and more or less 

 villose, and dark brown the following year, and armed with thin straight spines 

 l^'-l' long, or unarmed. 



Distribution. Dry sandy soil of the Pine barrens of northeastern Florida; abun- 

 dant in the neighborhood of Jacksonville. 



107. Crataegus lacrimata. Small. 



Leaves obovate, rounded or acute and glandular-serrate at the apex, usually with 

 incurved teeth, entire and glandular below, gradually narrowed from above the 

 middle to the base, and 3-nerved, with slender yellow nerves, numerous thin second- 

 ary veins and reticulate veinlets, when the flowers open early in April nearly fully 

 grown, light yellow, glabrous, with the exception of small tufts of pale caducous 

 hairs in the axils of the nerves below, and at maturity subcoriaceous, lustrous, \'-^' 

 long, about ^' wide; their petioles slender, wing-margined toward the apex, dark 

 orange-brown, at first puberulous, soon becoming glabrous, j'-^ long. Flowers 

 about f in diameter, on short stout glabrous pedicels, in 3-5-flowered simple 

 corymbs, with long linear entire caducous bracts and bractlets turning red in fading; 

 calyx-tube broadly obconic, glabrous, the lobes gradually narrowed from broad bases, 

 acuminate, entire, tipped with large dark glands; stamens 20; anthers large, light 

 yellow; styles usually 3, surrounded at the base by a narrow ring of pale hairs. 

 Fruit ripening toward the end of August, on slender pedicels, in 1 or 2-fruited 

 clusters, subglobose to short-oblong, full and rounded at the ends, dull brownish
