sional minute pale dots, 1.2-1.3, or rarely 1.4 cm. in diameter, and 
when oval once and a half as long as broad; calyx prominent, with 
a narrow deep cavity and appressed lobes often deciduous from the 
ripe fruit; flesh thin, light orange color, insipid; nutlets usually 3, 
rounded at the base, gradually narrowed and rounded at the apex, 
ridged on the back, with a broad deeply grooved ridge, penetrated 
on the inner faces by large shallow cavities, about 7 mm. long and 
4 mm. wide. 
A slender tree sometimes 7 m. high, with a trunk occasionally ro 
cm. in diameter, covered with rough gray bark, small spreading and 
recurved branches, and slender slightly zigzag branchlets marked by 
oblong pale lenticels, light yellow-green and glabrous when they 
first appear, light reddish or orange-brown and lustrous during their 
first season and gray-brown the following year, and armed with slen- 
der nearly straight chestnut-brown shining ultimately ashy gray 
spines 4-6 cm. long; or often a tall shrub with numerous ascending

Crataegus Emersoniana, n. sp. Leaves broadly ovate to oval, 
short-pointed and acuminate at the apex, rounded or cuneate at the 
entire base, sharply doubly serrate above, with straight or incurved 
glandular teeth, and divided above the middle into 3 or 4 pairs of 
short acuminate spreading lobes, nearly half-grown when the flowers 
open about the 2oth of May and then thin, light yellow-green, smooth 
and glabrous above with the exception of a few soft hairs near the 
base of the midribs and pale and sparingly villose below along the 
primary veins and in their axils, with short persistent hairs, and at 
maturity thin but firm, dark yellow and lustrous on the upper and 
paler on the lower surface, 5-6 cm. long and broad, with slender 
petioles wing-margined at the apex, slightly grooved, sparingly villose 
along the upper side while young, soon glabrous, occasionally glandu- 
lar, with minute dark deciduous glands, rose-colored in the autumn, 
2—2.5 cm. in length ; leaves on vigorous shoots usually rounded at the 
base, more deeply lobed, 8-10 cm. long and broad, with stout 
broadly winged petioles glandular through the season. Flowers 
about 2 cm. in diameter, on long slender glabrous pedicels, in 7—15- 
flowered compound corymbs ; calyx-tube narrowly obconic, glabrous, 
the lobes slender, acuminate and red at the apex, slightly dentate 
above the middle, glabrous on the outer, sparingly villose on the 
inner surface, reflexed after anthesis; stamens ro; anthers pale 
yellow ; styles 3-5, surrounded at the base by a narrow ring of scat- 
tered white hairs. Fruit ripening at the end of September, on slen-
