flesh yellowish green, firm and bitter; nutlets 3-5, rounded at the 

 broad base, narrow and, when 5, acute at the apex, rounded and ridged 

 on the back, with a broad grooved ridge, 7-7.5 mm. long and 4-4.5 mm. 

 wide. 



A tree 6-7 m. high, with a short trunk sometimes 1.6 dm. in diameter 

 and covered with gray scaly bark, long slender horizontal or drooping 

 branches, stout nearly straight branchlets dark orange-green, slightly 

 pubescent and marked by small pale lenticels when they first appear, 

 becoming light orange-brown in their first season and dull reddish brown 

 and glabrous the following year, and armed with numerous slender 

 nearly straight chestnut brown shining spines 3-5 cm. long, persistent 

 and becoming compound and sometimes 10 cm. in length on old stems 

 and branches. 



Borders of woods at Indian Dale, near Kutztown, Berks County, 

 C. L. Gruber, (No. 227 type) August 4 and October 2, 1905, May 10 

 and 22, 1906. 



Very distinct from C. punctata Jacquin in the shape of the thin nearly 

 glabrous leaves with much more slender veins, in the glabrous calyx- 

 tube and only slightly hairy corymbs, and in its smaller globose hardly 

 punctate fruit which is rounded and not truncate at the ends. 



4. Crataegus porrecta Ashe. 



Ann. Carnegie Mus., I, pt. Ill, 391 (1903). 



Leaves oblong-obovate, acute or acuminate and often abruptly 

 pointed at the apex, gradually narrowed to the long concave-cuneate 

 entire base, coarsely doubly serrate usually only above the middle, 

 with large straight glandular teeth, and often slightly divided toward 

 the apex into 4 or 5 pairs of narrow acuminate lobes; nearly fullv 

 grown when the flowers open early in May and then dark 

 yellow-green, smooth, lustrous and glabrous with the exception of a 

 few hairs on the midribs above, and paler and sparingly villose on 

 the midribs below, and at maturity thin but firm in texture, dark 

 yellow-green on the upper surface, paler on the lower surface, 6-S 

 cm. long and 3.5-4 cm. wide, with thick midribs and thin prominent 

 primary veins; petioles stout, narrowly wing-margined nearly to the 

 base, slightly hairy on the upper side while young, soon becoming- 

 glabrous, occasionally glandular, 1-1.5 cm. in length. Floicers 1.5- 

 1.7 cm. in diameter, on long stout slightly villose pedicels, in small 

 compact mostly 7- or 8-flowered corymbs, the much elongated lower 

 peduncles from the axils of upper leaves; calyx-tube narrowly obconic, 

 slightly villose, the lobes long, slender, acuminate, entire or occa- 

 sionally minutely dentate near the middle, glabrous, reflexed after
