and will probably prove to be a common plant when better known. 

 It has been collected by J. A. Shafer, in Allegheny county ; W. \V. 

 Ashe, in Bucks county, and l'>. 11. .Smith, in Delaware county. While 

 preferring the rich moist soils near streams, it yet occurs on dryer up- 

 lands. It is related to C. punctata Jacq., from which it is separated 

 by the lighter colored anthers, and fewer stamens and seed, and more 

 lucid foliage ; and to C. porrccta, proposed below, from which it is sepa- 

 rated by the different outline of the foliage, more oblong fruit and 

 fewer seeds. The large glossy foliage of C. paiisiaca renders it a con- 

 spicuous and handsome tree. 



Cr.vt.kous porrect.v n. sp. A tree 6-8 m. in height with a trunk 

 often I dm. thick, and long horizontal branches forming a globose or 

 tlattened crown ; the bark on the trunk dark gray, and broken into 

 thin, broad plates ; that on the branches smooth and light gray. Twigs 

 stout, glabrous, nearly straight, bright brown, armed with rather few 

 short, slender thorns, 3-4 cm. long. Leaves thick and subcoriaceous, 

 glabrous, dark green above, somewhat paler beneath, obovate or spat- 

 ulate, 5-9 cm. long, 3-4 cm. wide, rounded or abruptly acute at the 

 apex (or on vigorous shoots lobed and acuminate) cuneate and entire 

 at base, and gradually narrowed into the winged petiole, 1-2 cm. long, 

 sharply and doubly serrate above the middle with ascending teeth, 5-7 

 pairs of straight parallel ascending veins, prominent below and deeply 

 impressed above. The flowers, borne in large compound many- 

 tlowered glabrous or slightly pubescent corymbs on nodding pedicels, 

 are 15-17 mni. wide; calyx-lobes linear, entire, glabrate, reflexed 

 after anthesis ; stamens 8—14, slender, anthers pale pink ; styles 2-3. 

 The fruit, borne in large compound clusters on drooping pedicels, is 

 globose or slightly oblong, 15-19 mm. long, sparingly pruinose, dull 

 dark red, and capped by the slender spreading calyx-lobes, ripening 

 late in October and falling after the leaves and while the flesh is yet 

 green ; cavity deep and narrow ; flesh hard, green, bitter ; seed 2-3, 

 7-9 nun. long, somewhat ridged on the back. 



This plant, like C. grandis Ashe (Journ. E. Mitch. Sci. Soc. 17 : p. 

 2: 9) has many characters which are intermediate between the cnis-galli 

 diXiA punctata groups, and it is referable to either. It is common on 

 dry slopes around Pittsburg, Pennsylvania, where it has been collected 

 by J. A. Shafer and W. W. Ashe. 



Crat^gus pre.mora n. sp. A shrub 1-1.5 mm. in height with 

 numerous ascending branches from near the base of the stem. Twigs
