and become convex by the infolding of the two sides, a peculiarity 
which makes it always easy to recognize Crataegus Pringlei in the 
field. The habit of the Bald Mountain plant is also quite different 
from that of Crataegus Pringlei which is arborescent, with a tall well 
formed trunk. 
CRATAEGUS ANOMALA, Sargent, RHODORA, iii. 74 (1901) ; Siwa N. 
Am. xii. 187, t. 670. During the season of 1902 Mr.J.. G. Jack 
has found a number of trees of this species formerly known only in a 
few individuals, near Caughnawaga and on Ile Perrot in the St. Law- 
rence River. What appears to be Crataegus anomala has been 
collected at Crown Point, New York, by W. W. Eggleston, May 
1902, and by Charles H. Peck, May and September 1902, and at 
Hampton, New York, by W. W. Eggleston, May and October 1902. 
§ LOBULATAE. 
CRATAEGUS LOBULATA, Sargent, RHODORA, iii. 22 (1901); Silva 
N. Am. xii. 117 t. 75. A large tree of this species just out of bloom, 
with unusually hairy corymbs, was found on the 31st of May, 1902, 
by Ezra Brainerd and C. S. Sargent in a meadow by the road leading 
from Great Barrington to Alford, Massachusetts. Crataegus lobulata 
has also been collected at Stanford, Connecticut, by Æ. H. Eames; 
in May and September r9or, and September 1902. 
Crataegus Robesoniana, n. sp. Leaves ovate, acute or acu- 
minate rounded, truncate or rarely broadly cuneate at the base, sharply 
and often doubly serrate, with straight gland-tipped teeth, and divided 
into numerous short acute lateral lobes; nearly fully grown when the 
flowers open and covered above with short rigid pale hairs; at matu- 
rity membranaceous, light yellow-green and scabrous on the upper 
surface, pale and glabrous on the lower surface with the exception of 
a few short hairs scattered along the light yellow midribs and primary 
veins, 8—9 cm. long, 7-8 cm. wide, or on leading shoots often ro cm. 
long and 9 cm. wide; petioles slender, nearly terete, occasionally 
glandular, often tinged with red in the autumn, 3-4 cm. long. Flow- 
ers about 1.5 cm. in diameter on stout pedicels covered with long white 
reflexed hairs, in-very compact few-, usually 5-flowered compound 
corymbs; bracts and bractlets linear to oblong-obovate, glandular, 
caducous; calyx-tube narrowly obconic, villose, the lobes gradually 
narrowed from broad bases, linear, long-pointed, irregularly gland- 
ular-serrate, villose, reflexed after anthesis; stamens ro; anthers 
small, rose-purple; styles 4 or 5. Fruit in erect few-fruited clusters, 
oblong, full and rounded at the ends, bright scarlet, lustrous, marked 
by few large dots about 2 cm. long and 1 cm. wide; calyx sessile,
