Chapins\'ille, New York, C. S. Sargent, October, 1902 ; Chippewa, 

 Ontario, John Dunbar, October 15, 1902. 



This distinct and handsome species which is particularly beautiful 

 in spring when the branches are entirely covered with the abundant 

 clusters of large flowers, is named for Milton Stephen Baxter, of 

 Rochester, an enthusiastic and careful student of Crataegus. 



Crataegus verecunda, n. sp. 



Glabrous with the exception of the hairs on the young leaves and 

 on the inner face of the calyx-lobes. Leaves oblong-obovate or rarely 

 oval, acute or acuminate, gradually narrowed from near the middle, 

 and concave-cuneate at the entire glandular or crenate base, finely 

 doubly serrate above, with straight gland-tipped teeth, and divided 

 above the middle into several short broad acute lobes ; slightly tinged 

 with red and sparingly villose on the upper surface as they unfold, 

 and nearly fully grown when the flowers open and then very thin, 

 nearly glabrous and dark yellow-green above and pale below ; at 

 maturity thin, scabrate, light bluish-green on the upper surface, pale 

 on the lower surface, 5-6 cm. long, 3.5-4 cm. wide, with slender 

 yellow midribs and 4 or 5 pairs of thin primary veins ; petioles 

 slender, more or less wing-margined by the decurrent bases of the 

 leaf-blades, grooved, sparingly glandular, with minute mostly decidu- 

 ous glands, from 1.5-2 cm. in length ; leaves on vigorous shoots 

 usually broadly ovate, acute, concave-cuneate at the base, deeply 

 divided into 3 or 4 pairs of broad lateral lobes, 6-7 cm. long, from 

 5.5-6.5 cm. wide, with stout very glandular petioles usually wing- 

 margined to below the middle and generally rose color in the autumn. 

 Flowers about 1.4 cm. in diameter on long slender pedicels, in com- 

 pact usually 6-io-flowered thin-branched compound corymbs ; bracts 

 and bractlets oblong-obovate to linear, acuminate, coarsely glandular- 

 serrate, large and conspicuous, generally deciduous before the flowers 

 open ; calyx-tube narrowly obconic, the lobes abruptly narrowed at 

 the base, long-acuminate, coarsely glandular-serrate above the middle, 

 villose on the inner surface, reflexed after anthesis ; stamens 7 ; 

 anthers small, creamy white ; styles 2 or 3. Fruit on slender droop- 

 ing pedicels, in few-fruited clusters, oblong to oblong-obovate, about 

 I cm. long and 7 mm. wide ; calyx prominent, with a short tube, a 

 deep narrow cavity, and reflexed lobes mostly deciduous from the 

 ripe fruit ; flesh thin, yellow, dry and mealy ; nutlets 2 or 3, thick, 

 acute at the ends, prominently ridged on the back, with a high 

 rounded ridge, 7 mm. long.
