 14. Crataegus pygmaea n. sp. 



Leaves oval, acuminate, gradually narrowed and concave-cuneate at 

 the entire base, coarsely doubly serrate above, with spreading teeth 

 tipped with large dark glands, not lobed, more than half-grown when 

 the flowers open about the 25th of May and then membranaceous, 

 yellow-green and roughened above by short white hairs, and light 

 yellow-green and glabrous below, and at maturity thin but firm in 

 texture, dark yellow-green, smooth or scabrate on the upper and pale 

 on the lower surface, 4-4.5 cm. long and 2-2.5 cm. wide, with slender 

 midribs tinged with red below, and obscure primary veins; petioles 

 slender, wing-margined at the apex, slightly grooved on the upper side, 

 glabrous, glandular while young with numerous dark caducous glands, 

 dark red early in the season, 1.5-1.8 cm. in length ; stipules linear, obo- 

 vate, finely glandular-serrate, mostly deciduous before the flowers 

 open; leaves on vigorous shoots ovate, rounded or concave-cuneate at 

 the broad base, coarsely serrate, divided above the middle by broad 

 shallow sinuses into short acute lobes, subcoriaceous and sometimes 6 

 cm. long and 5 cm. wide, with stout broadly winged petioles furnished 

 with persistent glands, and foliaceous lunate coarsely glandular-serrate 

 stipules. Flowers about 1.5 cm. in diameter, on slender glabrous pedi- 

 cels, in 5-7-flowered simple corymbs, with linear acute glandular bracts 

 and bractlets, fading red and mostly persistent until the flowers open; 

 calyx broadly obconic, the lobes narrow, acuminate, glabrous, entire or 

 finely and irregularly glandular-serrate above the middle; stamens 5; 

 anthers cream color, faintly tinged with pink ; styles 2-4. Fruit ripening 

 about the 20th of September, on slender erect pedicels, in 1-4-fruited 

 clusters, oblong-obovate, rounded at the apex, gradually narrowed to 

 the base, dark crimson, lustrous, marked by occasional small pale dots, 

 1.2-1.4 cm. long, 8-11 mm. wide; calyx prominent, with a short tube, 

 a deep narrow cavity and much enlarged coarsely serrate reflexed 

 and appressed lobes dark red on the upper side below the middle, and 

 mostly persistent on the ripe fruit; flesh thin, dark yellow, dry and 

 mealy; nutlets usually 3, obtuse and rounded at the ends, ridged on 

 the back, with a broad often grooved ridge, dark colored, 6-7 mm. long 

 and about 5 mm. wide. 



A shrub, with slender stems 1-2 m. high covered with pale gray bark, 

 and slender nearly straight branchlets marked by numerous small pale 

 lenticels, green more or less tinged with red when they first appear, 

 bright chestnut-ljrown and lustrous at the end of their first sea^^on and
