autumn. In spring there is produced a more imperfect rosette, 
and some of the leaves at the very base of the stem commonly 
remain nearly to the time of flowering and sometimes even later, 
especially in shady places. The seedling rosette, the late autumnal 
rosette, the persistence of the lowest leaves, I have never met with 
in wild or cultivated specimens of H. strictum, H. crocatum, 
H. cori/mbusum, and H. py'mnanthoides. 
From U. Juranum it differs in havhig the stem scabrous, the 
leaves much less amplexicaul and without distinct amdcles, not 
so conspicuously paler beneath and commonly more hairy above ; 
the panicle when polycephalous does not produce numerous 
branches terminating in small corymbs, the anthodes are con- 
siderably larger, the perianth-segments not thickly clothed with 
short, thick, gland-tipped hairs, and the ligules not disthictly 
cihated at the apex. In the garden H. Dewari flowers about a 
fortnight or three weeks later than H. Juranum. There is, how- 
ever, a striking similarity between small specimens of the two in 
which the branches of the panicle terminate in solitary heads ; 
and I should not be surprised to hear that H. Dewari was the plant 
Dickson had from Harehead Wood, Selkh’k, and that he sent 
H. Juranum to Mr. Borrer from his own garden, believmg it to be 
the same as the wild plant. 
H. Dewari bears some resemblance to the broader-leaved states 
of H. gothicum, but differs in the leaves being semi-amplexicaul, 
with a greater tendency to be ovate in outline and less denticulate 
on the margins. I have never seen it with the distinctly-toothed 
leaves so frequent in H. gothicum. The leaves are of a much 
brighter green, and not so much paler beneath; they are also more 
hahy. The panicle when polycephalous has not the same tendency 
to produce branches terminating in corymbs. The anthodes are 
considerably smaller, the inner phyllaries less attenuated and much 
more hairy. 
From H. strictum it differs (in addition to the points abeady 
stated) by having the stem scabrous, the leaves broader in the 
middle and more attenuated at each end ; and more conspicuously 
by the long straggling branches of the polycephalous panicle. 
But the greatest stress must he laid on the fact of its producing a 
true rosette. All the specimens Mr. Backhouse has gone over in 
herbaria I have access to he has named H. strictum. 
H. corgmbosiim, Fries, and H. crocatum, Fries, differ still more 
widely from H. Dewari than does H. strictum. Both, especially 
H. corgmbosum, have the stem leaves much more numerous, more 
parallel-sided, and the polycephalous panicle with the branches 
ending in small corymbs. H. crocatum also has the pericline 
much larger, more abrupt at the base, and with far fewer hairs. 
H. corgmbosum has the leaves more glabrous, and neither the one 
nor the other produces rosettes. 
At one time I thought it might be D. elatum, of Fries; but as I 
now possess Lhideberg’s ‘Hieracia Scandinavise Exsiccata,’ I can 
say without hesitation that it is not No. 92 of that collection. 
I believe its nearest ally is H. Dovrense, Fries, but the polycephalous
