which, are much smaller than the root-leaves, the lowest one dis- 

 tinctly stalked. Anthodes small, 5 to 15, in a compact corymb, 

 with the peduncles short and arching-ascending. Pericline ovate 

 at the base, oblong - cylindrical after flowering ; phyllaries nu- 

 merous, acute, the inner ones acuminate, dark-olive, sparingly 

 clothed with stellate down and black gland-tipped setae, or occa- 

 sionally with white simple hairs. Plorets glabrous or indistinctly 

 ciliated. Styles livid-yellow. Plant green or slightly ceesious. 



Var. a, genuinum. 

 Phyllaries densely clothed with black gland-tipped hairs. 



Var. 0, canescens. 



Leaves green 



Phyllaries without gland-tipped hairs, but with numerous 

 white simple hairs. Leaves green. 



Var. 7, sub-ccBsium, Pries ? 



Phyllaries nearly destitute of gland-tipped hairs, but with 

 numerous simple white or white-tipped hairs. Leaves glaucous, 

 the one on the stem small and sessile. 



On rocks and walls. Common in mountainous districts ; rare 

 and rather sparingly distributed on low ground. Var. 3, on lime- 

 stone rocks, near Knaresborough, Yorkshire ; var. 7, on the walls 

 of Pountains Abbey, near Kipon, Yorkshire. 



England, Scotland, Ireland. Perennial. Summer 

 and Autumn. 



Stem 9 inches to 2 feet high. Leaves very variable in form, 

 but generally abrupt or even sub-cordate at the base ; in the most

 middle, but frequently there is a smaller sessile one above, and 

 nearly as commonly no leaf at all, or a small bract-like one above 

 the middle ; the margins^ are usually remotely denticulate or 

 dentate, the teeth increasing in size towards the base, and pointing 

 outwards or backwards. 



Mr. Backhouse gives a variety rotundatimi found in Canlochen 

 Glen, but I am unable to see the characters which separate it from

Mr. Baker has favoured me with two plants from his garden, 

 which represent my varieties /3 and 7. Both of these are destitute

 in the ordinary state of H. murorum. The first of these he con-
