Synonyms: Curled Silesian (d.), Hend.; Fr. Laitue hative de 
Silésie, Vil. 
Very closely resembles the Early Simpson lettuce. The leaves 
are a little less waved, and not quite so yellowish; the whole plant is 
a little less compact; but the most conspicuous difference is that the 
mature plant is more open in the center, forming little appearance 
of a head. The stem is rather less paniculate; seeds white. 
Mentioned by Fessenden in 1828, and described by Brown in 
1854. | 
No. 19, Earty Dwarr Brown Forcrne, Ben., ’83. 
Young plant pale green, washed with brown; leaves roundish or 
oval, apex retuse, margin of inner leaves somewhat undulate, sur- 
face of all more or less blistered, of inner ones puffed and densely 
blistered; veins inconspicuous. | 
Mature plant seven inches in diameter, the densely blistered leaves 
much washed with reddish brown; head small, oblong, one and one 
half inches in diameter, the inner leaves very much, and very finely

borders of leaves, usually undulate; stem short, slender, smooth,
