CRATAEGUS IN MISSOURI.—II. 81 
surface, hoary-tomentose on the lower surface, 8-9 cm. long and 6-7 
cm. wide, with slender midribs and 4 or 5 pairs of thin primary veins 
extending to the points of the lobes; petioles slender, slightly wing- 
margined at the apex, tomentose early in the season, becoming vil- 
lose, 2.5-8 cm. in length; leaves on vigorous shoots ovate, acuminate, 
more or less deeply cordate, more coarsely serrate and often 10 cm. 
long and broad. Flowers up to 3.5 cm. in diameter, on stout pedi- 
cels, in compact, mostly 7-15-flowered corymbs, with oblong-obovate 
acuminate falcate villose bracts and bractlets persistent until the 
flowers open; calyx-tube broadly obconic, thickly covered like the 
pedicels with long matted pale hairs; calyx-lobes gradually nar- 
rowed from wide bases, acuminate, laciniately glandular-serrate, 
villose; stamens 20; anthers rose color; disk broad, deeply fluted, 
lemon yellow; styles 4 or 5. Fruit ripening in October, on slender 
hairy pedicels in few-fruited drooping clusters, short-oblong, rounded 
and pubescent at the ends, crimson, marked by small pale dots; calyx- 
cavity narrow, deep, pointed in the bottom, the lobes erect, often 
deciduous from the ripe fruit; flesh thick, dry and mealy; nutlets 4 or 
5, rounded at the ends, rounded and slightly grooved on the back, 
about 7 mm. long and 3.5 mm. wide, the hypostyle extending to the 
middle of the nutlet. 
A small tree with a tall slender stem 8-10 cm. in diam- 
eter, covered with dark scaly bark, few erect slender 
branches and stout slightly zigzag branchlets coated when 
they first appear with matted white hairs, becoming nearly 
glabrous, reddish brown, lustrous and marked by small pale 
lenticels at the end of their first season and light gray- 
brown in their second year, and armed with numerous slen- 
der straight chestnut brown spines 2.5-4 cm. long. 
In rich moist soil along Turkey Creek, near Joplin, Joplin 
County, rare (EZ. J. Palmer, 34, type, April 18, 19 and 23, 
and October 1, 1909; 4A, April 23, 1909). 
This species is related to C. lanuginosa Sargent of the same 
region but differs from it in its larger, thinner and smoother 
leaves and in their longer petioles. The flowers, which 
open two weeks earlier, are much larger and perhaps as 
large or larger than those of any American species. The 
fruit differs in a less conspicuous calyx with a narrow cav- 
ity pointed in the bottom, while that of the fruit of Cratae- 
gus lanuginosa is shallow and broad at the bottom. The 
hypostyle of the nutlets of Crataegus lanuginosa is much
