ter on long slender slightly villose pedicels, in broad compound many- 
flowered thin-branched hairy corymbs; bracts and bractlets linear, 
small, caducous ; calyx-tube broadly obconic, villose at the base, gla- 
brous above, the lobes linear, acuminate, sparingly glandular-serrate, 
mostly only above the middle, villose on the inner surface, reflexed 
after anthesis; stamens ro; anthers pink; styles 3-5, surrounded at 
the base by a broad ring of pale tomentum. Fruit on stout glabrous 
or slightly hairy pedicels, in broad drooping many-fruited clusters, 
oblong, full and rounded at the ends, crimson, lustrous, marked by 
large pale dots, 1—1.2 cm. long, 9-10 cm. wide; calyx sessile, with 
a broad deep cavity and much elongated lobes gradually narrowed 
from broad bases, villose and dark red on the upper side toward the 
base; flesh thin, juicy, greenish white; nutlets 3—5, full and rounded 
at the ends, conspicuously ridge on the broad back, with a high nar- 
row ridge, about 7 mm. long. 
A shrub with numerous ascending stems 5-7 m. in height, and 
stout slightly zigzag branchlets marked by many large pale lenticels, 
dark yellow-green when they first appear, light red-brown and lus- 
trous during their first season, gray tinged with red the following 
year, and armed with many stout straight or slightly curved bright 
red-brown lustrous ultimately ashy gray spines, on some individuals 
about 4 cm. long and on others from 8—r10 cm. in length, and often 
furnished near the middle with a short lateral branch. Flowers at the 
end of May or early in June. Fruit ripens at the end of September.

This species resembles Crataegus acutiloba, Sargent (RHODORA, iii. 
23), in the shape of its deeply lobed leaves, but differs from that 
species in its much larger flowers, in its villose corymbs and large 
fruits, and in the great size of the spines on some individuals, the 
largest of these being larger than those of any other species of this 
group which I have seen. Crataegus acutiloba, based on specimens 
gathered on Mt. Desert Island and at other points on the coast of 
Maine will, in view of the collections made during the last two years 
in the St. Lawrence valley, and western New England, be found prob- 
ably to be confined to the coast region north of Massachusetts Bay. 
CRATAEGUS MATURA, Sargent, RHopora, iii. 24 (1901). This 
early-ripening species was first seen by Mr. Ezra Brainerd and myself 
near Middlebury, Vermont, in August and September r9oo, and the
