Crataegus dayana n. sp. 



Leaves broadly ovate, acuminate, abruptly concave-cuneate or 

 rounded at the entire or glandular base, sharply doubly serrate, with 

 slender glandular teeth, and divided into 6 or 7 pairs of narrow 

 acuminate spreading lateral looes ; when they unfold tinged with 

 rose color and coated with soft white hairs more abundant on the 

 lower than on the upper surface, nearly two thirds grown when the 

 flowers open the last week of May and then very thin, yellow-green 

 and scabrate above and pale and slightly hairy along the midribs 

 and veins below, with short sometimes persistent hairs, and at ma- 

 turity thin, dark yellow-green, smooth and glabrous on the upper 

 surface, pale on the lower surface, 8-10 cm long and 7-9 cm wide, 

 with stout midribs, and primary veins arching to the point of the 

 lobes ; petioles slender, wing-margined at the apex, slightly villose 

 while young, becoming glabrous, rose colored in the autumn, 3-4 

 cm in length ; stipules linear, only slightly glandular, fading brown, 

 caducous ; leaves on vigorous shoots thicker, cordate at the broad 

 base, very coarsely serrate, more deeply lobed and often lo-ii cm 

 long and wide, with stout glandular red petioles 2-2.5 cni in length, 

 and foliaceous lunate glandular serrate deciduous stipules. Flowers 

 2-2.2 cm in diameter, on long stout slightly hairy pedicels, in wide 

 lax long-branched usually 10-14 flowered corymbs, the lower ped- 

 uncles from the axils of upper leaves ; calyx-tube narrowly obconic, 

 glabrous, the lobes gradually narrowed from broad bases, long, 

 acuminate, coarsely glandular serrate above the middle, glabrous on
