brooke. Everywhere in dry slopes about Swainston, Bowledge, &c. ; also about 

 Westover, in the great plantation, &c., often with lilac flowers. 



Root thick, woody and creeping. Stem 6 — 18 inches high, round, clothed above 

 with close-pressed deflexed hairs, smooth and naked for the most part towards the 

 base, simple or branched in an opposite manner. Radical leaves partly ovate, 

 blunt, on short petioles, variously cut, inciso-serrate, sometimes simply ovate or 

 lanceolate, hairy ; those above them pinnatifid, with lanceolate and cut segments, 

 the uppermost deeply divided into linear-acute and nearly smooth segments. In- 

 volucre of many linear-acute leaves. Florets on a common receptacle, each 

 accompanied by a lanceolate, concave, hairy scale. 



This species does not appear to be a native of Ireland, and is by no means com- 

 mon in Scotland.
