turning dull yellow and falling the middle of October before the fruit ; 

 petiole slender, teeth, 2-4 cm. long, grooved above. The flowers, 

 which appear the last of May in large many-flowered compound gla- 

 brous corymbs, are 16-22 mm. wide, cup-shaped and on slender elon- 

 gated glabrous drooping pedicels ; calyx glabrous, the large glabrous 

 triangular lobes sharply serrate, ascending after anthesis ; stamens 

 5-8, large, anthers rose-purple. The fruit, borne in glabrous, i-sev- 

 eral- fruited often compound clusters on long, spreading or nodding or

Cratiegi/s cristata is frequent in the vicinity of Pittsburg, Pennsyl- 

 vania, preferring meadows and fresh soils, where it has been collected 

 by J. A. Shafer and W. W. Ashe. It is most closely related to C. 

 Hobnesiaiia Ashe, from which it is separated by the thicker, more 

 globular fruit and different leaf-outline. 



Cr.^t^gus brumalis n. sp. A small tree 4-6 m. in height, with 

 a short, slender, sparingly armed trunk, seldom more than i dm. thick,

 on the trunk dark gray-brown, firm, with shallow furrows; that on the 

 branches dull gray, or olivaceous, and smooth. Twigs stout, orange to 

 dark green, becoming gray the second year, flexuous, armed with very

 broadly cuneate at base, sharply and finely doubly serrate nearly to 

 the base, 3-4 pairs of short broad notches, the lowest broadest and 

 spreading; petiole nearly terete, slender, 2-4 cm. long, narrowly 

 winged above. The flowers, which appear the last of May in glabrous 

 small compound many-flowered corymbs, are about 16 mm. wide, and 

 borne on slender drooping pedicels ; calyx obconic, glabrous, the nar- 

 row serrate or entire lobes reflexed, or spreading after anthesis ; stamens
