being still more prominently present in them. The cuttings taken 

 from Glen Fiagh in 1889 have flowered in the garden at Shirley 

 this last spring, and the plant proves to be male. The catkin 

 differs little from that of S. herbacea, excepting in point of size, 

 being i in. long ; the two leaves on the peduncles and the leaves of 

 the young shoots at the time of flowering look like reticulata leaves 

 on herbacea petioles. 



FURTHER NOTES ON HIERACIA NEW TO BRITAIN. 



By Frederick J. Hanbury, F.L.S. 



(Continued from p. 261.) 



Hieracium britannicum, n. sp. — A well-defined and cha- 

 racteristic plant of the extensive limestone districts of Central 

 Britain. I owe my first acquaintance with it to the Rev. W. H. 

 Purchas, who, for two or three years before I was able to gather it 

 for myself, sent me a liberal supply of dried specimens, also roots 

 for growing, accompanied by several critical notes of interest. It 

 is to be found under various names in some of the older herbaria, 

 and must be well known by sight to many British botanists. 



Belonging to the same wide group as the last, it may be readily 

 recognized by the extraordinarily conspicuous parallel veining (best 

 seen on the under side), and deep acute toothing, of the radical 

 leaves ; the teeth, pinnae, or appendages, often extending a long 

 way down the petiole. Ranging in height from about 12 to 18 in., 

 the stem is commonly leafless, or bears one large leaf near the base, 

 and a mere bract at the point of branching, striate, with few short 

 scattered hairs ; peduncles rather long, slightly arcuate, very 

 floccose, with numerous seta3 and simple hairs interspersed. Heads 

 usually from 3 to 6, rather large. Involucre truncate at the base, 

 ultimately conical, grey with stellate down and long white hairs, a 

 few setae being interspersed. Phyllaries long, narrow, and acute, 

 porrect in bud. Lignles glabrous at the tips. Styles almost yellow, 

 rather dusky on the under surface, rarely pure yellow. Outer 

 radical leaves broadly ovate, apiculate, sub-entire near the apex, 

 but becoming very coarsely toothed towards the remarkably trun- 

 cate base. Inner leaves narrower, more acute, less truncate and 

 more deeply toothed. All of a firm texture, glaucous and glabrous 

 above, much furrowed by the deep veining, and clothed on the 

 tinder surface and margins with loose white hairs. 



It grows in profusion in many of the limestone dales and scars 

 ot Derbyshire, Staffordshire, and Yorkshire. Besides gathering it 

 myself in these three counties, I have received it from The Pinch 

 and Dovedale, Derbyshire, and Sugarloaf Rock, Wetton, North 

 btaffordshire, through the Rev. W. H. Purchas ; from Chee Dale 

 and Attermire Crags, Settle, through the Rev. W. H. Painter; from 

 rocks between Buxton and Millers Dale, through Mr. J. C. Melvill.
