3. Crataegus angustata, n. sp. 



Leaves narrow-obovate, acuminate and occasionally abruptly short- 

 pointed at the apex, gradually narrowed from above the middle to the 

 long slender cuneate entire base, finely serrate above, with straight gland- 

 ular teeth, and often slightly divided above the middle into 2 or 3 pairs of 

 small lobes; more than half- grown when the flowers open from the 10th 

 to the middle of April and then thin, dark yellow-green and covered above 

 by short white hairs and paler and slightly villose along the midribs and 

 veins below, and at maturity thin but firm in texture, dark yellow-green, 



smooth and lustrous on the upper surface, paler on the lower surface, 

 2.5—4 cm. long and 1.5-1.8 cm, wide, with prominent yellow midribs, and 

 thin conspicuous yellow primary veins extending very obliquely toward 

 the end of the leaf. Flowers about 1.2 cm. in diameter, on long slender 

 villose pedicels, in narrow 4-10-flowered corymbs, the elongated lower 

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

 pubescent, the lobes slender, acuminate and rose-colored at the apex, 

 glandular-serrate above the middle, villose, reflexed after anthesis; stamens 

 20; anthers pale rose color; styles 4 or 5. Fruit ripening and falling 

 at the end of September or early in October, on short nearly glabrous 

 drooping pedicels, in few-fruited clusters, subglobose or often rather 

 broader than high, crimson, more or less blotched with green, marked by 

 large pale dots, 1.2-1.4 cm. in diameter; calyx prominent, with a broad 

 deep cavity, and elongated spreading persistent lobes; flesh thick, green, 

 hard and dry; nutlets 4 or 5, gradually narrowed and rounded at the ends, 

 ridged on the back, with a narrow high ridge, 6— 6.5 mm. long, and 3.5-4 mm. 



wide. 



A much-branched round-topped shrub 3-5 m. high, with 

 stout stems covered with dark scaly bark, small erect and 

 spreading branches, and slender nearly straight branchlets "T" ^^ 



hoary-tomentosc when they first appear, becoming glabrous \ 

 and light chestnut-brown in their first season and reddish 

 brown the following year, and armed with very numerous 

 slender straight or slightly curved gray spines 3.5-6 cm. long.
