 The Garden Lettuce, cultivated widely throughout the Bombay Presidency 

 and generally throughout India. A very excellent variety which 

 Woodrow has named the Poona Brown Cos was introduced into Poona 

 more than 40 years ago, and has become a favorite with market 

 gardeners. It is a large lettuce of the true Cos form and black-seeded, 

 the leaves are a rich brown outside, greeuish-white inside, tender, crisp, 

 and of good flavor. The seed is procurable from any Poona seed- 

 merchant. PI. B. I. V. 3, p. 404; Grab. Cat. p. 94 ;" Dalz. & Gibs.
