variety, and its several weaknesses
prevent amateurs from growing it widely. The variety originated with
Stephen W. Underhill, Croton-on-Hudson, New York, from seed of Concord
pollinated by Black Prince. It fruited first in 1866.

Vine vigorous, precariously hardy, unproductive. Canes rough,
thick, reddish-brown with light bloom; nodes enlarged, flattened
internodes long; tendrils continuous, long, bifid or trifid.
Leaves thick; upper surface dark green, glossy, smooth to rugose;
lobes five; terminal lobe acute; petiolar sinus deep; lateral
sinus wide, narrowing towards top, deep. Flowers open in
mid-season, self-sterile; stamens reflexed.

Fruit mid-season, keeps well. Clusters large, long, tapering,
single-or double-shouldered, compact; pedicel long, slender with
few warts; brush short, pale green. Berries variable in size,
oval, black, glossy with thick bloom; skin tender, thin, adherent
with wine-colored pigment; flesh pale green, translucent, tender,
vinous; good. Seeds free, one to four, large.

BLACK HAMBURG

(Vinifera)

Black Hamburg (Plate VI) is an old European sort, long the mainstay in
forcing-houses in Belgium, England and America and now popular out of
doors in California. It is an excellent table-grape but, while it
keeps well, its tender skin does not permit its being shipped far,
especially when grown out of doors. The vine is subject to disease.
The following description of the fruit is made from grapes grown in
the greenhouse:

Bunches very large, often a foot in length and weighing several
pounds; very broad at the shoulder and gradually tapering to a
point; compact, oftentimes too compact; berries very large, round
or slightly round-oval; skin rather thick; dark purple becoming
black at full maturity; flesh firm, juicy, sweet and rich; quality
very good or best. Season early in the forcing-house but rather
late out of doors.

BLACK MALVOISE

(Vinifera)

This variety is rather widely grown in California as an early
table-grape and might be worth trying in eastern grape regions. While
the fruit is not of the best quality, it is good. The following
description is compiled:

Vine vigorous, healthy and productive; wood long-jointed, rather
slender, light brown. Leaves of medium size, oval, evenly and
deeply five-lobed; basal sinus open, with nearly parallel sides;
upper surface smooth, almo
