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. Periclinc 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 seta), or occa- 
sionally with white simple hairs. Florets glabrous or indistinctly 
ciliated. Styles livid-yellow. Plant green or slightly ca3sious. 
Var. a, genuinum. 
Phyllaries densely clothed with black gland-tipped hairs. 
Leaves green. 
Var. 0, canescens. 
Phyllaries without gland-tipped hairs, but with numerous 
white simple hairs. Leaves green. 
Var. 7, sub-ccesium, Pries? 
Phyllaries nearly destitute of gland-tipped hairs, but with 
numerous simple white or white-tipped hairs. Leaves glaucous,

On rocks and walls. Common in mountainous districts ; rare 
and rather sparingly distributed on low ground. Var. 0, on lime-

England, Scotland, Ireland. Perennial. Summer 
and Autumn. 
Stem 9 inches to 2 feet high. Leaves very variable in form,

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 rotnndatum found in Canlochen 
, 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 y. Both of these are destitute

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