 COEIAWDES IS the seed like fruit of Coriandium 

 satiium, Linn , an umbelliferous annual of S Europe 

 The plant grows 2-3 ft high glabrous strong smelling 

 with Ivs. divided into almost thread-like divisions, and 

 small-white fls. The plant is easily grown in garden 

 soil. It occasionally becomes spontaneous about old 

 yards. The seeds (or fruits) are used as seasoning and 

 flavoring in pastries, confections and liquors, although 

 they are less known in this country than caraway. The 

 plaiit is occasionally cultivated in Amer. gardens along 

 with sweet herbs.

 Pliny). Coriaridceie. Shrubs or perennial herbs: 

 Ivs. deciduous, entire, 3-9-nerved, opposite and disti-
