teeth, and sometimes slightly divided above the middle into 2 or 3 

 pairs of small acute lobes ; nearly half grown when the flowers open 

 the middle of June and then thin, light yellow-green and slightly 

 roughened above by short white hairs and pale and villose on the 

 midribs and veins below, and at maturity thin but firm in texture, 

 dark yellow-green, glabrous and smooth on the upper surface, still 

 villose on the lower surface along the stout midribs and prominent 

 primary veins, 6-8 cm long and 4.5-5 cm wide ; petioles stout, wing- 

 margined to below the middle, tomentose early in the season, becom- 

 ing pubescent or nearly glabrous, 8-12 mm in length. Flowers 

 1. 3-1. 6 cm in diameter, on short stout villose pedicels, in compact 

 mostly 15-18-flowered hairy corymbs, the elongated lower peduncles 

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

 with long matted white hairs, the lobes long, slender, acuminate, 

 glabrous on the outer, villose on the inner surface, reflexed after 

 anthesis ; stamens 12-20; anthers rose color; styles 2, surrounded 

 at the base by. a narrow ring of pale tomentum. Fruit ripening 

 late in September, on slightly hairy red drooping pedicels, in few- 

 fruited clusters, oval or slightly obovate, crimson, lustrous, marked 

 by small pale dots, 9-10 mm long, and 6-7 in diameter; calyx little 

 enlarged, with a short tube, a deep wide cavity, and small spread- 

 ing and appressed often deciduous lobes dark red and villose on the 

 upper side ; flesh thin, yellow, dry and mealy ; nutlets 2, rounded 

 at the ends, rounded and slightly ridged on the back, penetrated 

 on the inner faces by large deep cavities, 5-5.5 mm long, and 3-3.5 

 mm wide. 



A shrub 3-4 m high, with numerous small erect stems covered 

 with ashy gray bark, small ascending slightly spreading branches 

 forming an open head, slender nearly straight branchlets covered 

 when they first appear with long matted white hairs, becoming light 

 orange-brown or chestnut-brown, lustrous, puberulous and marked 

 by pale lenticels at the end of their first season, and dull reddish 

 brown in their second or third years, and armed with straight 

 slender chestnut-brown and shining ultimately dull gray spines 3-4 

 cm long, occasionally persistent and compound on old stems.

 18 and September 21, 1906 (#78), June and October 1906, 1907. 



Well distinguished from Crataegus tomentosa Linneus, 

 by the color of the branches and spines, the smaller number of 

 stamens, and by the shape and color of the fruit. 



Anthers pink ; stamens 20
