Crataegus Jackii,n.sp. Leaves obovate-cuneate to oblong-cune- 
ate or rarely oval, acute, or on vigorous shoots broadly ovate and 
rounded or cordate at the base, to orbicular, finely and doubly 
serrate except toward the base, with incurved glandular teeth, and 
sometimes slightly divided above the middle into short acute lobes ; 
tinged with red and villose-pubescent above, this often as they unfold 
and nearly fully grown and almost glabrous when the flowers open ; 
at maturity thin but firm in texture, dark dull green on the upper 
surface, pale on the lower surface, 3-4 cm. long, 2-3 cm. wide, or on 
leading shoots often 5 cm. in diameter, with stout midribs and 3 or 4 
pairs of slender primary veins extending to the points of the lobes ; 
petioles slender, more or less wing-margined toward the apex, glandu- 
lar, with numerous small bright red glands, mostly deciduous before 
autumn, 3-4 cm. long; stipules oblong-obovate to linear, acuminate, 
glandular-serrate, caducous. Flowers 2 cm. in diameter, in broad 
many-flowered thin-branched compound villose corymbs ; bracts and 
bractlets conspicuous, oblong-obovate, glandular-serrate ; calyx-tube

bases, oblong, acuminate, coarsely glandular-serrate, slightly villose 
on the upper surface, reflexed after anthesis; stamens 5—ro, usually 
5; anthers pale yellow ; styles 2 or 3, surrounded at the base by a

glabrous clusters, ovate to oblong, prominently angled, full and 
rounded at the ends, dull dark red, marked by occasional small pale 
dots, 1.2—1.4 cm. long, 1-1.2 cm. thick; calyx small, with a narrow
