E. H. Eames (nos. 144 type! 3495 and 3595), June and September 
1901, May and September 1903. 
Crataegus Robbinsiana, n. sp. Leaves ovate, acute or acumi- 
nate. rounded, truncate or cordate*at the entire or crenate base, finely 
doubly serrate above, with straight glandular teeth, and more or less 
divided into 4 or 5 pairs of spreading acuminate lateral lobes, when 
they unfold deeply tinged with red, glabrous below and furnished 
above with short white hairs, nearly fully grown when the flowers 
open from the middle to the zoth of May and then membranaceous, 
pale yellow-green and still hairy above and pale below, and at ma- 
turity thin but firm in texture, smooth and dark green on the upper, 
pale on the lower surface, 3-5 cm. long and 2.5-3.5 cm. wide, with 
slender yellow midribs, and thin primary veins extending obliquely 
to the points of the lobes, often turning orange color tinged with red 
in the autumn before falling; petioles slender, slightly wing-margined 
at the apex, glandular, with minute stipitate dark glands, 1.4-2 cm. 
in length; stipules linear to linear-falcate, acuminate, finely glandular- 
serrate, mostly deciduous before the flowers open; leaves on vigorous 
shoots broadly ovate, mostly long-pointed, cordate or rarely truncate 
at the base, more coarsely serrate, more deeply lobed and fre- 
quently 6-7 cm. long and 5-6 cm. wide, with stout reddish conspic- 
uously glandular petioles 1-2 cm. long. Flowers 1.2-1.5 cm. in 
diameter, on slender glabrous pedicels, in 6—10-flowered corymbs, 
with linear glandular bracts and bractlets fading brown and mostly 
deciduous before the flowers open; calyx-tube broadly obconic, gla- 
brous, the lobes gradually narrowed from wide bases, acuminate at 
the gland-tipped apex, entire or slightly and irregularly toothed near 
the middle, reflexed after anthesis; stamens 7-10; anthers light rose 
color; styles 4 or 5, surrounded at the base by a ring of pale tomen- 
tum. Fruit ripening from the first to the middle of October, on slen- 
der pedicels, in few-fruited erect clusters, depressed-globose, rather 
broader than high, dull red and slightly pruinose, becoming lustrous 
and about 1.2 cm. in diameter; calyx little enlarged, without a tube, 
and with a deep narrow cavity, and spreading appressed lobes bright 
red on the upper side below the middle and mostly persistent on the 
ripe fruit; flesh thin, hard, greenish white; nutlets 4 or 5, full and 
rounded at the base, narrow and rounded at the apex, ridged on the 
back, with a high ridge, 6-7 mm. long and 4-5 mm. wide. 
A tree occasionally ro m. high, with a tall trunk 20-25 cm. in 
diameter, covered with light gray closely appressed scales, compara- 
tively small erect branches forming an open erect head, and slender 
slightly zigzag branchlets marked by numerous dark lenticels, green 
tinged with red and glabrous when they first appear, bright chestnut- 
brown and lustrous during their first winter and pale gray-brown 
the following season, and armed with many slender or occasionally
