arge size, yellowish-green, pointed, slightly undulated,
entire on the borders, and often revoluted like those of the
White-seeded. It rarely produces a head; or, if so, it is loose and
open. Its greatest perfection is obtained by collecting the exterior
leaves about the top of the plant, and tying them loosely together.

The variety is not considered superior to the White-seeded, though both
of the sorts are inferior to the Paris Cos or Florence sorts.

WHITE BRUNOY COS (WHITE-SEEDED). _Vil._

The heads of this variety are long and loose, and rarely form well
unless the exterior leaves are tied loosely together. It somewhat
resembles the Alphange in the form and character of its foliage, though
the head is longer and larger.

The plant attains a remarkable size, is hardy, and of good quality; but
soon runs to seed, and appears to be a winter rather than a summer
lettuce.

WHITE PARIS COS. _Vil._ _M'Int._

London White Cos. Sutton's Superb White Cos.

The head of this variety has the form of the Green Paris, and blanches
well without tying; the outside leaves are erect, yellowish-green, and
rather numerous. The extreme diameter of the entire plant, when well
grown, is about fourteen inches, and its weight nearly twenty-four
ounces. The seeds are white.

This is the sort most generally grown by the London market-gardeners,
millions of it being produced annually within a few miles of London
alone; and it has been adopted almost exclusively, by the gardeners of
Paris, for cultivation in the open air. Next to the Green Paris Cos,
this is the best, the largest, and the longest in running to seed, of
all the summer lettuces. It is tender, brittle, and mild flavored, less
hardy and a few days later than the Green Paris Cos.

ENDIVE-LEAVED LETTUCE. _Trans._

Lactuca intybacea.

The leaves of this species have the form of those of some of the
varieties of Endive; whence the name. They are small, pale-green, broad
towards the ends, cut and irregularly lobed on the borders. While young,
the plants have the appearance of Green Curled Endive.

As it runs to flower much earlier than the Spinach Lettuce, it is less
esteemed than that variety. The seeds should be sown thickly, in shallow
drills ten or twelve inches apart; and the plants should be cut for use
when they are three or four inches high.

PERENNIAL LETTUCE. _Vil._

Lactuca perennis.

This species is a native of Europe; and, in habit and duration, i
