The Flora of Wiltshire. 



Locality. In waste places, and by road-sides and borders ofl 

 fields. B. Fl. August. Area, 1. 2. 3. 4. 5. Probably jrequerm 

 throughout Wilts. It is conspicuous on account of its long branches! 

 and large heads, which latter much exceed in magnitude those of; 

 either of the other species. 



2. A. minus, (Schk.) lesser Burdock. Engl. Bot. t. 1228. Reich.l 

 Icones xv., t. 811. Bab. Ann. Nat. Hist. ser. iii. vol. xv. p. 187. 



Locality. Waste ground and newly cut copses. B. Fl. August. 

 Area, 1. 2. 3. 4. 5. Ln all the Districts. A smaller plant than the 

 preceding, with heads about half the size. A. intermedium, 

 (Lange) should be looked for in the county. It grows principally 

 in woods. The distribution of the above species require further 

 study in Wilts. I would particularly refer the student to Pro- 

 fessor Babington's paper " On the British species of Arctium," in 

 the " Ann. of Nat. Hist." ser. iii., vol. xv. 



Serratula, (Linn.) Saw-wort. 

 Linn. CI. xix. Ord. i. 



Name. A diminutive of serra, (Lat.) a saw ; in allusion to the 

 leaves of the plant, which are serrated. 



1. S. tinctoria, (Linn.) common or Dyer's Saw-wort. The plant 

 being used for the purpose of dyeing. Engl. Bot. t. 38. St. 3, 16. 



Locality. In woods, hedges, and thickets, mostly on clay. P, 



I. July, August. Fr. September, October. Area, 1. 2. 3. 4. 5. 

 Not frequently distributed in the county. Stem, 2 or 3 feet high, 

 angular, rigid, branched. Leaves sometimes nearly entire, the 

 sharp serratures excepted. Flowers dark purple. The flowers and I 

 general aspect of the saw-wort remind one of some species of 

 Centaurea. 



Centaurea, (Linn.) Knapweed. 

 Linn. CI. xix. Ord. iii. 



Name. Said to be named after the Centaur Chiron, who first 

 used the plant medicinally. 



1. C. nigra, (Linn.) black discoid Knapweed. Engl. Bot. t. 278. | 

 (inv. not good.) Reich. Lcones xv., t. 761. 



Locality. In meadows, pastures, borders of fields, and road-!
