 lar, pubescent; fruit more villous. If.. H. Native of the

 leaflets pinnatifid or bipinnatifid : segments lanceolate or oblong,

 garis not only in the leaves being simply pinnate, but in the in- 

 volucra being usually wanting, in the involucels being shorter 

 than the umbellules, and in the furrows of the fruit b&ing fur- 

 nished with 2 vittae, and the commissure with 4.

 sive of the synonymes. Fruit glabrous. It agrees in habit with 

 Athamanta Pyrenaica, Jacq. hort. vind. t. 197., the Libanotis
