bably in October, on stout glabrous pedicels, ellipsoidal, dark red, the 

 calyx with a short tube, spreading and reflexed lobes and a shallow wide 

 cavity pointed in the bottom, 6 or 7 mm. long and 5 or 6 mm. wide; nutlets 

 2 or 3, acute at apex, rounded at base, slightly grooved on the back, pene- 

 trated on the inner face by short grooves, 5 mm. long and 3 mm. wide, 

 with a narrow hypostyle extending to the middle. 



A stout shrub 2-3 m. high, covered with gray scaly bark, thick erect 

 pale gray branches and stout branchlets yellow-green and sparingly covered 

 with pale hairs when they first appear, becoming red-brown and glabrous 

 in their second season and armed with numerous stout straight chestnut 

 brown lustrous spines 4-6.5 cm. long, becoming branched and persistent 

 on old stems.

Crataegus kingstonensis (§ Anomalae), n. sp. 



Leaves elliptic to broad-ovate, acuminate at apex, gradually narrowed 

 and cuneate or rarely rounded at base, divided toward the apex into short 

 acuminate spreading lobes, and coarsely often doubly serrate above the 

 middle with straight glandular teeth, thin, glabrous, dark yellow-green, 

 smooth and lustrous above, pale or glabrous below, 5-7 cm. long and 4-5 

 cm. wide, with a slender midrib and primary veins; petioles slender, 1-1.5 

 cm. in length. Flowers opening early in June on long slender pedicels 

 in lax mostly 7- 10-flowered glabrous corymbs; calyx-tube broad-obconic, 

 glabrous, the lobes gradually narrowed from the base, acuminate, sharply 

 serrate or entire, glabrous on the outer surface, puberulous on the inner 

 surface; stamens 20; anthers bright red; styles 4 or 5. Fruit ripening the 

 middle of October, subglobose, about 1.5 cm. in diameter, dark red, with 

 soft succulent flesh; the calyx little enlarged with spreading appressed 

 lobes and a deep narrow cavity rounded in the bottom; nutlets 4 or 5, 

 rounded at the ends, ridged on the back with a low grooved ridge, obscurely 

 grooved on the inner faces, 6-7 mm. long and 5-6 mm. wide, the narrow 

 hypostyle extending to the middle. 



A tree 7-8 m. high, with a trunk 2 m. long, and stout glabrous branchlets 

 yellow-green when they first appear, becoming dark chestnut brown and 

 lustrous by the end of the first season and dull red-brown the following 

 year, and armed with many stout nearly straight chestnut-brown spines 

 3-4 cm. in length.

This is an interesting addition to the small number of Anomalae 

 with glabrous corymbs and 20 stamens. It is most closely related to C. 

 fallsiana Sarg. from Little Falls, Herkimer County, New York, with the 

 same shaped leaves and the same succulent fruit, but the flowers and 

 fruit of the Kingston tree are much larger. The two species are more
