ROSACES 441 



many-fruited slightly villose clusters, obovate to oblong, gradually narrowed to the 

 rounded base, crimson, lustrous, marked by large pale dots, slightly villose, particu- 

 larly toward the full and rounded apex, |' |' long, ^'-f' wide; calyx large and promi- 

 nent, with elongated acuminate lobes abruptly narrowed from broad bases, dark red 

 on the upper side, tomentose on the lower, finely glandular-serrate, spreading or 

 closely appressed, often deciduous before the ripening of the fruit; flesh thin, light 

 yellow, somewhat juicy; nutlets 4 or 5, thin, prominently and irregularly ridged on 

 the back, %'-&' long. 



A bushy tree, sometimes 20 high, with a short trunk 6' in diameter, covered with 

 pale gray-brown scaly bark, stout ascending branches, and slender somewhat zigzag 

 brauchlets at first dark green and villose, with long matted white hairs, and puberu- 

 lous and light orange-brown during their first season, becoming glabrous and orange- 

 brown or bright red, and armed with numerous stout straight or slightly curved 

 bright chestnut-brown spines l^'-2' long. 



Distribution. Low limestone ridges near the banks of the St. Lawrence River 

 iu the Caughnawaga Indian Reservation opposite Lachiue in the Province of Quebec. 



74. Crataegus Ellwangeriana, Sarg. 



Leaves oval, acute, full and rounded or broadly cuneate at the entire base, irreg- 

 ularly divided usually only above the middle into numerous short acute lobes, and 

 coarsely and often doubly serrate, with straight or incurved glandular teeth, about 



half grown when the flowers open the middle of May, and then roughened above by 

 short pale hairs and villose below along the slender midribs and primary veins, and 

 at maturity membranaceous, light green and scabrous on the upper surface, pale and 

 nearly glabrous on the lower surface, 2^'-3' long and 2'-3' wide; their petioles slen- 

 der, at first villose, finally glabrous, l'-2' long; stipules oblong-obovate, acute, villose, 

 coarsely glandular-serrate, ^' long, those of the upper leaves mostly persistent until 

 after the ripening of the fruit. Flowers 1' in diameter, on short stout hairy pedicels, 

 in many-flowered densely villose corymbs; calyx-tube broadly obconic and villose, the 

 lobes elongated, lanceolate, glandular, with small pale stalked glands, villose on both 

 surfaces; stamens 10, sometimes 8; anthers small, rose color; styles 3-5. Fruit 

 ripening and falling at the end of September, on slender glabrous pedicels, in droop-
