24. Crataegus pausiaca, Ashe. 



Leaves oblong-obovate to oval, rounded or acute at the apex, gradually narrowed 

 from near the middle to the concave-cuneate entire base, and finely doubly serrate 

 .above, with straight glandular teeth, more than half grown when the flowers open 

 from the 20th to the end of May and then membranaceous, dark yellow-green, 

 and slightly villose above and along the under side of the midribs and veins, and at 

 maturity glabrous, dark yellow-green above, paler below, 2'-2^' long, li'-l^' wide, 

 with slender yellow midribs and 5 or 6 pairs of primary veins extending very 

 obliquely to the end of the leaf; their petioles slender, wing-margined above the 

 middle, villose only early in the season, f'-l' long; on vigorous shoots elliptical to 

 rhomboidal, long-pointed, slightly or deeply divided into broad lateral lobes, very 

 coarsely serrate, often 3^-4' long and 2'-21' wide, with foliaceous lunate glandular- 

 serrate stipules often ^' long and rather longer than the stout petioles. Flowers ^' 



in diameter, on long slender hairy pedicels, in broad many-flowered thin-branched 

 villose corymbs, the linear bracts and bractlets mostly deciduous before the flowers 

 open; calyx-tube narrowly obconic, villose below, with closely appressed white hairs, 

 glabrous above, the lobes abruptly narrowed from the base, slender, acuminate, tipped 

 with minute dark glands, entire or occasionally obscurely toothed above the middle, 

 glabrous on the outer, villose on the inner surface; stamens 10-15, rarely 20; anthers 

 dark rose color; styles 2 or 3, surrounded at the base by a broad ring of pale tomentum. 

 Fruit ripening about the middle of October, in drooping many-fruited clusters, on 

 elongated slender slightly hairy pedicels, oblong to slightly obovate, full and rounded 

 at the ends, dull brick-red, marked by large pale dots, ^Y~^g' ^^^S> about f wide ; 

 calyx small, with spreading appressed lobes mostly deciduous from the ripe fruit; 

 flesh thin, hard, slightly juicy, green or greenish yellow; nutlets 3 or 4, thin, acute 

 or obtuse at the ends, very prominently ridged on the back, with a high broad deeply 

 grooved ridge, about ^ long. 



A tree, 20-25 high, with a tall straight trunk often a foot in diameter, covered 

 with dark brown scaly bark, stout wide-spreading branches forming a broad symmet- 

 rical round or flat-topped head, slender straight branchlets light orange-green and 

 sparingly villose at first, becoming light orange-brown during their first season, light 

 or dark gray-brown the following year, and armed with numerous stout slender
