inch long, two to three times
the length of the calyx; stamens numerous: ovary with style deeply
5-parted.

=Fruit.=--June to July. In drooping racemes, globose, passing through
various colors to reddish, purplish, or black purple, long-stemmed,
sweet and edible without decided flavor.

=Horticultural Value.=--Hardy throughout New England; grows in all soils
and situations except in wet lands, but prefers deep, rich, moist loam;
very irregular in its habit of growth, sometimes forming a shrub, at
other times a slender, unsymmetrical tree, and again a symmetrical tree
with well-defined trunk. Its beautiful flowers, clean growth, attractive
fruit and autumn foliage make it a desirable plant in landscape
plantations where it can be grouped with other trees. Occasionally in
nurseries; procurable from collectors.

CRATAEGUS.

A revision of genus _Crataegus_ has long been a desideratum with
botanists. The present year has added numerous new species, most of
which must be regarded as provisional until sufficient time has elapsed
to note more carefully the limits of variation in previously existing
species and to eliminate possible hybrids. During the present period of
uncertainty it seems best to exclude most of the new species from the
manuals until their status has been satisfactorily established by
raising plants from the seed, or by prolonged observation over wide
areas.

COCKSPUR THORN.

Rich soils, edge of swamps.

Quebec to Manitoba.

Found sparingly in western Vermont (_Flora of Vermont_, 1900); southern
Connecticut (C. H. Bissell).

South to Georgia; west to Iowa.

A small tree, 10-25 feet in height and 6-12 inches in trunk diameter;
best distinguished by its thorns and leaves.

Thorns numerous, straight, long (2-4 inches), slender; leaves thick,
smooth, dark green, shining on the upper surface, pale beneath, turning
dark orange red in autumn; outline obovate-oblanceolate, serrate above,
entire or nearly so near base; apex acute or rounded; base decidedly
wedge-shaped shaped; leafstalks short.

Fruit globose or very slightly pear-shaped, remaining on the tree
throughout the winter.

Hardy throughout southern New England; used frequently for a hedge
plant.
