Green Winter Cos. Vil.
Head elongated, somewhat of the form of the preceding variety; deep-green, and not forming well, unless the exterior leaves are tied together at the tips; the outer leaves are large, erect, concave, toothed on the margin, and prominently blistered; the seeds are black.
It blanches well; but the ribs and nerves of the leaves are comparatively coarse and hard. Well adapted to winter culture; but, as a summer lettuce, of little value.
Monstrous Brown Cos. Vil.
Two-headed.
Head of remarkable size, long, loose, and open; leaves large, equalling in size those of the Alphange or Florence Cos; green, washed with brown; pointed; seeds white.
The plant sends out numerous side-shoots, or suckers; and sometimes produces several distinct heads: these, however, are generally loosely formed, and not of the fine, tender quality of the Paris varieties.
Oak-Leaved Cos.
Romaine à Feuille de Chêne. Vil.
The Oak-leaved Lettuce produces no head, but forms a loose and open heart at the centre of the plant. The leaves are numerous, bronze-green, and deeply cut, or lobed, on the margin, in the form of the leaves of some species of the oak; the seeds are black.
