A shrub 3 or 4 m. in height with numerous erect stems covered 

 with smooth pale gray bark, fastigate branches forming a narrow pointed 

 head, and slender only slightly zigzag branchlets light red-brown when 

 they first appear, dark reddish brown, lustrous, and marked by 

 numerous small jiale Icnticels at the end of their first season, becoming 

 dark reddish brown the following year, and armed with many stout, 

 straight or slightly curved bright red-brown shining spines from 3.5-4 

 cm. in length and frequently long persistent ; winter-buds appearing 

 pale by the production of the light yellow inner scales beyond the 

 brown outer scales. Flowers during the first week of June. Fruit

Crataegus colorata, n. sp. 



Glabrous with the exception of the hairs on the upper surface of 

 the young leaves. Leaves oblong-ovate, acuminate, full and rounded 

 or abruptly cuneate at the entire base, coarsely doubly serrate above, 

 with straight gland-tipped teeth, and slightly divided into 4 or 5 pairs 

 of short acuminate spreading lobes, deeply tinged with red and villose 

 on the upper surface, with short white hairs when they first appear, 

 and about half-grown when the flowers open and then very thin, light 

 yellow-green more or less tinged with red, aud still slightly hairy 

 above ; at maturity thin but firm in texture, dark yellow-green, 

 smooth and lustrous on the upper surface, pale bluish green on the 

 lower surface 6-8 cm. long, 5-6 cm. wide, with slender yellow midribs 

 and 4 or 5 pairs of thin primary veins arching obliquely to the points 

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

 grooved, sparingly glandular, from 3 to 4 cm. in length ; bracts and 

 bractlets lanceolate to oblong-obovate, acute, glandular, bright red, 

 large and conspicuous, mostly deciduous before the flowers open ; on 

 leading vigorous shoots leaves broadly ovate, accuminate, rounded or 

 slightly cordate at the base, more coarsely serrate and more deeply 

 lobed than the leaves of fertile branchlets, often 8-9 cm. long and 

 wide, with very stout glandular petioles, becoming reddish toward the 

 autumn, and large foliaceous lunate acuminate coarsely serrate per- 

 sistent stipules. Flowers 1.5 cm. in diameter on long slender pedicels, 

 in wide many-flowered thin-branched compound corymbs ; bracts and 

 bractlets lanceolate to linear, glandular, with small stipitate glands,
