 oblong-linear, very sharply and incisely serrate, with bristle-pointed 

 teeth ; the uppermost leaves sessile ; involucres two-leaved. Umbels 

 of 3-5 rays which are longer than the involucels. Umbellets 2i" in 

 diameter, exceeding the oblong-lanceolate and entire divisions t>f the

 cylindrical ; the carpels rounded on the back ; the 5 primary ribs thick 

 and prominent, and the oil-tubes under the intervening furrows. 

 Biennial or perennial glabrous herbs, with pinnately decompound 

 leaves, the segments linear; compound umbels with no involucres 

 and yellowish flowers. 



A small genus ; one or more of the species now widely dispersed. 



FCENICULUM VULGARE Gr&Hn. Stock perennial. Stems erect,
