28. Crataegus verruculosa, Sarg., n. sp. 



Leaves obovate to rlioinboidal, acute or rarely rounded at the apex, cuneate and 

 entire at the base, and sharply often doubly serrate above, with straight or incurved 

 glandular teeth, when they unfold dark red, covered above by short pale hairs and 



below by long matted white hairs most abundant on the midribs and veins, about 

 half grown when the flowers open from the 1st to the 10th of May and then thin, 

 dark yellow-green, and scabrate on the upper surface and paler and pubescent on 

 the lower surface, and at maturity subcoriaceous, dark green, lustrous, and nearly 

 smooth above, pale and still pubescent below on the stout midribs and conspic- 

 uous primary veins extending very obliquely toward the end of the leaf, 1^-2' 

 long, I'-lj wide; their petioles stout, wing-margined at the apex, at first villose, 

 becoming pubescent or puberulous, \'-^ long; on vigorous shoots often broadly 

 ovate to oval, sharply doubly serrate, with straight teeth, sometimes slightly 

 lobed above the middle, with short acute lobes, and frequently 3' long and 2' 

 wide. Flo"wers |' in diameter, on long slender villose pedicels, in broad lax com- 

 pound 6-12 usually 9-flowered villose corymbs, with reddish purple minutely gland- 

 ular caducous bracts and bractlets; calyx-tube broadly obconic, thickly covered 

 with matted pale hairs, the lobes gradually narrowed from broad bases, slender, 

 acute, tinged with red at the apex, sparingly glandular-serrate, pubescent; stamens 

 20; anthers pale rose color; styles 3-5 surrounded at the base by a broad ring of 

 long pale hairs. Fruit ripening the 1st of October, on stout pubescent pedicels, in 

 drooping few-fruited clusters, subglobose, somewhat flattened and pubescent at the 

 ends, dark red; calyx prominent, with more or less deciduous lobes; nutlets 3-5, 

 narrowed and acute at the ends, rounded and very irregularly ridged and sometimes 

 obscurely grooved on the back, about \' long. 



A tree, 20-25 high, with a tall trunk 10'-12' in diameter, thick spreading 

 branches forming a broad compact round-topped symmetrical head, and stout nearly 

 straight branchlets thickly covered with matted pale hairs when they first appear, be- 

 coming reddish or orange-brown, nearly glabrous and roughened by minute tubercles 

 at the end of their first season, gray-brown the following year, and armed with numer- 

 ous straight stout or slender dark chestnut-brown very lustrous spines |'-1' long.
