colored antlicrs and in the larger fruit on drooping pedicels, ripening in 



July and August.

Crataegus aestivalis var. cerasoides f. luculenta, n. forma. — Crataegus 

 luculenta Sargent, Trees and Shrubs, I. 11, t. 6 (1902). 



Differing from the var. cerasoides in the more broadly obovate leaves, in 

 the more numerous hairs on their upper surface while young, the rather 

 smaller flowers, the smaller and less juicy fruit, ripening at the end of June 

 or early in July, and in its often arborescent habit. 



Florida: Volusia County, "'Haw Creek." 



Crataegus rufula, nov. nom. — Crataegus aestivalis Torrey & Gray, N. 

 Am. Fl. I. 40R, in part (1840), not Mespilus aestivalis Walter. 



Leaves oldong-obovate, acute or rounded at ixpex, gradually narrowed, 

 cuneate and entire at base, finely crenately glandular-serrate, and often 

 slightly lobed with short rounded lobes above the middle; covered above 

 with soft i)ale hairs and whitish tomenlose below when they unfold, and at 

 maturity thick, dark green, lustrous and glabrous or slightly pubescent 

 along the midrib on the upper surface, rufous pubescent especially on the 

 midrib and veins on the lower surface, 2-3.7 cm. long and 1.8-3 cm. wide, 

 rarely not more than 2.5 cm. long and 1.2 cm. wide; petioles slender, villose- 

 pubescent with rufous hairs, occasionally glandular, 6-8 mm. in length; 

 leaves at the ends of vigorous shoots oblong-obovate, rounded and short- 

 pointed to elliptic and acuminate, laterally lobed or deeply 3-lobed at apex 

 and often G cm. long and 3.8 cm. wide. Flowers appearing from the 10th 

 to the end of March, 1.8-2.5 cm. in diameter, in mostly 3 5-flowered clus- 

 ters, on villose pubescent pedicels about 8 mm. in length; calyx-tube broadly 

 obconic, glabrous or villose-pubescent sometimes in the same cluster, the 

 lobes gradually narrowed from a wide l)ase, acuminate, entire or slightly 

 glandular-serrate nearly to apex, glabrous or slightly pubescent on the 

 outer surface; stamens 20; anthers dark rose'color; styles 3-5, surrounded 

 at base by a ring of white tomentum. Fruit ripening the end of May, often 

 solitary on glabrous erect pedicels 6-12 mm. long, subglobose, scarlet, lus- 

 trous, about 1.2 cm. in diameter, with yellow juicy subacid flesh, the calyx 

 persistent, with erect lobes; nutlets rounded and only slightly grooved on 



the back, about 6 mm. long. 



A tree sometimes 10 m. high, with a tall trunk 20-25 cm. in diameter, 

 covered with rough deeply furrowed dark bark, paler and less deeply 

 furrowed on smaller and younger stems, stout, ascending and spreading 

 branches fonning a broad round-topped head, and slender slightly zigzag 

 branchlets covered when they first appear with pale tomentum, glabrous 

 or rusty tomentose until the early summer, becoming chestnut-brown, lus- 

 trous and glabrous before autumn, and dull gray in their second year, and 



unarmed or armed with slender or stout straight spines 1.2-3.8 cm. in length.
