shoots are often quite large. The fruit is pear 
shaped, orange colored, in erect clusters, and ripens in 
October. 
The Large Spined Thorn, Crataegus macracantha, 
is found in considerable quantity in Western New 
York, and throughout Ontario, Canada, and around 
Quebec. It is quite abundant on the steep banks of 
the Genesee River, on the north side of the city of 
Rochester. The enormous spines, from which the 
species takes its name, are peculiar to this form, and 
they are quite often five inches in length. It comes 
into flower about May 31. The blossoms are borne 
on large compound corymbose clusters and the indi- 
vidual flowers are cup shaped ; about three-quarters 
of an inch in diameter, with ten stamens, white an- 
thers, and two styles. The deep green, handsome

leaves are broadly ovate, wedge shaped, or rounded at 
the base, and coriaceous at maturity. The large clus- 
ters of showy red fruit, which is smaller than in any 
of the other sections of Crataegus, ripen in October, 
and hang on in good condition until about December 
first, after which they shrivel and hang for some 
considerable time on the bushes. This species is usu- 
ally shrubby in habit and occasionally forms a hand- 
some bush twelve feet or more in height, and as much 
in diameter. 
Crataegus Durobrivensis, a new species recently 
described and named by Dr. Sargent, and first ob- 
served by the writer in the month of May, 1900, on 
the steep banks of the Genesee River, on the north 
side of the city of Rochester, is in the opinion of Dr. 
Sargent, “one of the most ornamental of the thorns 
of the Northern United States.” How widely distrib- 
uted this species may be is not yet known, but it was 
detected by Dr. Sargent last September on the banks 
of the Niagara River, and about the same time noticed 
by the writer outside the northern boundary of Dela- 
•ware Park in Bufifalo. 
Crataegus Durobrivensis comes into bloom about 
May 28. The flowers are large saucer shaped, about 
one inch in diameter, bearing twenty and occasionally 
twenty-five stamens, and beautiful rose colored an- 
thers. The flowers are borne in abundant, large 
corymbose clusters, in great profusion along the 
branches, and when a well developed individual of 
this species is in flower it certainly is striking in its 
beauty. The leaves are ovate, rounded at the base, 
from two to two and a half inches long, and fiom one 
inch and a quarter to one inch and a half wide. The 
deep crimson lustrous globese fruit ripens in October 
and is remarkably persistent, hanging on witho'-.t loss 
or change of color until almost midwinter, and pre- 
sents a cheerful appearance amidst the v/inter snows. 
The branches are noticeable for their olive green tint, 
approaching to ashy gray. It hardly ever assumes 
tree like proportions and grows from twelve to six- 
teen feet in height, and spreading from the ground. 
Crataegus Pringlei, which was first observed in the 
Champlain .Valley by C. G. Pringle, in May, 1877, and 
subsequently described and named by Dr. Sargent, 
is found growing in western New York, around To- 
ronto, and in Michigan and Illinois. A number of 
specimens of it grow along the Genesee River at 
Rochester. It comes into flower about May 23. The 
flowers are borne in large, downy compound corym- 
bose clusters. The blossoms are about seven-eighths 
of an inch in diameter, with ten stamens and pink or 
purple red .anthers. The leaves are usually oval 
pointed and square or cordate at the base, and when 
}'Oung are quite soft and downy. The young shoots 
and branchlets are quite downy in the early part of 
the season. The large oblong to spherical fruit is of a 
dull red color and quite sweet to the taste, to the ex- 
tent of almost being disagreeable, and ripens about 
September ist, and soon falls. The habit is usually 
low and spreading, occasionally becoming a small- 
sized tree, and it is noticeable for the habit of sending 
out across the top strong remote straggling shoots, 
and “it can be distinguished by its thin, drooping, oval 
leaves, which, except on vigorous shoots, are fre- 
quently convex by the gradual unfolding of the leaves 
from the midribs to the margins.” There is no doubt 
but that Crataegus Pringlei has been long con- 
founded with C. Mollis. 
Crataegus pedicillata, an arborescent species, first 
observed in the Park System of Rochester, jointly by 
Mr. C. C. Laney, superintendent of parks, and the 
writer, in the month of June, 1899, and lately described 
and named by Dr. Sargent, forms a very handsome 
tree, with a broad, shapely head. It comes into 
flower about May 23d. The blossoms are nearly 
three-quarters of an inch in diameter, borne on 
spreading, loose corymbs, with ten stamens and purple
