very slender, gray pubescent, brown or greenish, becoming gray and 

 glabrous the second year, armed with few very slender 2-3 cm. long 

 thorns. Leaves membranaceous, dark green and pubescent above 

 with short hairs, paler and rough pubescent beneath, the blades ovate 

 or broadly ovate in outline, 5-7 cm. long, 4-5 cm. wide, acute at apex, 

 rounded obtuse or truncate at base, finely and sharply serrate, 3-5 

 pairs of regular shallow notches; petiole stout, 1-1.5 cm. long, 

 pubescent, glandular, winged above, flattened. The flowers, which 

 appear about June ist, in 2-4-flowered narrow, villose cymes, 4-5 cm. 

 wide, are 16-20 mm. wide, saucer-shaped, ill-scented, and on short 

 erect pedicels ; calyx obconic, villose, the lanceolate, deeply gland- 

 ular serrate lobes reflexed after anthesis ; stamens 10, small, anthers 

 cream -colored ; styles 3. The fruit, borne in 2-4-fruited clusters on 

 short, erect strict pubescent pedicels, 1-2 cm. long, is globular, about 

 1.2 cm. long, full and rounded at both ends, pubescent, especially at 

 the ends, bright green with darker spots, capped by the broad elon- 

 gated calyx-tube (rarely with the brown reflexed lobes persistent), 

 ripening and falling after the leaves in the middle of October; flesh 

 green, hard, bitterish ; seeds 3, deeply grooved on the back, the lateral 

 faces plane. 



CratcBgus premora can be separated from C. modesta Sarg, to which 

 it is evidently related by the different outline of the foliage and the 

 shorter pedicels. Collected in the eastern part of Berks county, 

 Pennsylvania, by C. L. Gruber and W. W. Ashe. 



Crat^gus cristata n. sp. A small tree 4-8 m. in height with 

 a short stout unarmed trunk often i cim. thick, and numerous spread- 

 ing or ascending branches forming an oval crown ; the bark on the 

 trunk dark brown, broken into long thin close layers, inner bark 

 bright orange ; that on the flexuous branches smooth, bright olive- 

 green or grayish. Twigs stout, glabrous, flexuous, olive, orange, or 

 brown-purple, becoming gray the third year, armed with numerous 

 rather stout nearly straight red-brown thorns, 3-4.5 cm. long, the 

 wood soft and brittle. Leaves large, bright green, rather thin, at 

 maturity rough on both surfaces, on unfolding appressed pubescent 

 above, soon glabrous, ovate or broadly ovate, 6-8 cm. long, 5-7 cm. 

 wide, rounded or cordate at base, acuminate at the apex, sharply and 

 coarsely serrate nearly to the base, 4-6 pairs of sharp notches, 6-8 

 pairs of slender primary veins, the lower pairs arched and with 

 spreading or recurved tips, the upper ascending but the tips recurved,
