1921] SARGENT, NOTES ON NORTH AMERICAN TREES, IX. 5 



Texas. SanAugustineCounty, borders of upland woods near San Augus- 

 tine, E. J. Palmer, No. 10617 (2), September 17, 1916, No. 13239 (No. 2), April 

 1, 1918 (type). 



The distinct character in this species is the deep serration of the 

 leaves, unusual in plants of the Crus-galli Group. From C. Bushii Sargent, 

 the species of southern Arkansas, western Louisiana and eastern Texas 

 with 20 stamens and rose-colored anthers it is well distinguished by the 

 shape of the leaves. 



Crataegus intermixta ( 



Leaves elliptic to slightly obovate, acute, abruptly short-pointed or 

 rarely rounded at apex, gradually narrowed and cuneate at base, sharply 

 and doubly serrate above the middle with erect acuminate teeth, and on 

 leading shoots occasionally slightly lobed, glabrous, thin, 4-5 cm. long 

 and 2-2.5 cm. wide, with a thin midrib and 4 or 5 pairs of slender prom- 

 inent primary veins; petioles slender, slightly wing-margined toward the 

 apex, sparingly glandular, 1-1.5 cm. in length. Flowers appearing from 

 the middle to the 20th of May, about 1 cm. in diameter, on slender ped- 

 icels, in globose usually 5-10-flowered compact corymbs; calyx-tube 

 broad-obconic, glabrous, the lobes short, gradually narrowed, serrate 

 above the middle with occasional glandular teeth, glabrous on the outer 

 surface, soft-pubescent on the inner surface; stamens 20; anthers pink- 

 styles 1-3. Fruit ripening the end of October, subglobose to slightly 

 obovoid, dark orange-red, 10-12 mm. in diameter, crowned with the 

 only slightly enlarged calyx, with a deep cavity wide in the bottom, and 

 firm hard flesh; nutlets 2-3, rounded at the gradually narrowed ends, 

 about 8 mm. long and 5 mm. wide, with a low broad dorsal ridge; the 

 narrow dark hypostyle extending to the middle. 



A round-topped tree 5-6 m. high, with wide-spreading branches, a 

 trunk 17-25 cm. in diameter, dark scaly bark and slender glabrous slightly 

 zigzag branchlets dark orange-brown or reddish and lustrous in their 

 first season, becoming dull gray-brown and armed with many slender 

 nearly straight spines 3-5 cm. in length. 



Missouri. M a r i o n C o u n t y, uplands, Riverside Park, Hannibal, John Davis, 

 No 6, October 21, 1912, October 13, 1913, May 19, 1913 (type). 



This plant has the thin acute sharply serrate leaves of many of the 

 Virides species to which it bears a strong resemblance; the pink anthers, 

 however, are unusual in that group except in the extreme south, and the 

 1-3 styles, the large solid fruit, the shape of the nutlets, the numerous, 

 long spines and the rough bark all point to the Crus-galli Group to which 

 it is now doubtfully referred. 



Crataegus araioclada (§Crus-galli), n. sp. 



Leaves oblong-obovate, acute or very rarely rounded at apex, gradu- 

 ally narrowed and cuneate at base, finely serrate above the middle with 

 blunt or acute teeth, occasionally slightly and irregularly lobed, especially 

 on leading shoots, thin, glabrous with the exception of a few hairs early
