OEAT^GUS JSTEO-BUSHII, Saeg. 



(Iutricatse.) 

 Crat^gus Neo-Bushii, n. sp. 



Glabrous with the exception of a few hairs on the upper surface of the young leaves and 

 petioles. Leaves ovate to rhombic, acuminate, concave-cuneate and gradually narrowed to the 

 glandular base, sharply doubly serrate above, with straight or incurved glandular teeth, and 

 slightly divided usually only above the middle into three or four pairs of broad acuminate lobes; 

 when they unfold tinged with red and furnished with a few soft caducous white hairs on the upper 

 side of the midribs and veins; more than half grown when the flowers open and then very thin, 

 light yellow-green, and nearly glabrous, and at maturity thin, dark yellow-green, smooth and 

 rather lustrous on the upper surface, pale on the lower surface, from 5.6 to 7 centimetres long and 

 from 4.5 to 5 centimetres wide, with thin yellow midribs and primary veins; petioles slender, wing- 

 margmed at the apex, soon glabrous, glandular, with minute persistent glands, often rose-colored 

 toward the base in the autumn, from 1.5 to 2.5 centimetres in length; leaves on vigorous shoots 

 broadly ovate, usually cordate or occasionally truncate at the base, coarsely serrate, deeply and 

 occasionally almost three-lobed by narrow sinuses reaching nearly to the midribs, often from 7 to 

 8 centimetres long and from 6 to 7 centimetres wide, with broad-winged petioles and foliaceous 

 lunate coarsely serrate deciduous stipules. Flowers from 1.7 to 1.8 centimetres in diameter, on 

 long slender pedicels, in wide usually four or five-flowered corymbs, with obovate to linear 

 glandular-hispi J bracts and bractlets fading rose color and often persistent until after the flowers 

 open, the lowest peduncle from the axil of an upper leaf ; calyx-tube narrowly obconic, the lobes 

 broad, ab;urJ% narrowed and long-pointed at the entire apex, laciniately glandular-serrate below 

 the middle", reflexed after anthesis ; stamens ten ; anthers rose color ; styles two or three, surrounded 

 it the base by a ring of yellow hairs. Fruit on long erect stems, in wide mostly two or three- 

 fruited clusters, short-oblong to subglobose, orange-red, marked by numerous dark dots, from 1 

 to 1.2 centimetres in diameter; calyx prominent, with a deep wide cavity, and spreading coarsely 

 serrate persistent lobes; flesh thin, yellow-green, hard, and dry; nutlets two or three, obtuse, or 

 when three narrowed at the rounded ends, ridged on the back, with a broad deeply grooved ridge, 

 from 7 to 8 millimetres long and from 4 to 4.5 millimetres wide. 



A shrub, from 1.5 to 2 metres high, with slender nearly straight branchlets, dark orange-red 

 and marked by pale lenticels when they first appear, becoming chestnut-brown or purple and 

 lustrous m their first season and dull reddish brown the following year, and unarmed or armed, 

 with occasional short slender spines. Flowers appear from the 10th to the 15th of May. Fruit 

 ripens the middle of October. 



Dry gravelly soil near Monteer, Shannon County, Missouri, B. F. Bush, May 25, 1900 (No. 

 386), May 15 and October 2, 1905 (No. 10 A and 10 B type), May 14 and October 6, 1905 (No. 

 10), also October, 1905 (Nos. 10 D and 10 E). 



This plant is named for its discoverer, Mr. B. F. Bush, and is interesting as the only species of the Intricate group 

 that has been found west of the Mississippi River. This very natural group is composed of a number of small shrubs 

 chiefly confined to the northern states, where they occur from southern Michigan to Massachusetts, and southward to 

 eastern Pennsylvania, and along the Alleghany Mountains to northern Georgia and Alabama, where a few species are
