the following observations on the forms or sub-species of S. squa- 
lidus which he saw on the slopes of Mount Etna, where I have 
myself made a study of the forms of this variable species. “ S. 
Aetnefisis, Ten., leaves spathulate, slightly toothed or nearly entire; 
achenes glabrous. Grows in elevated regions of Mount Etna. 
S. squalidus, var. glaucescens, Spr., leaves irregularly and coarsely 
toothed ; achenes glabrous or pubescent. Grows in an intermediate 
belt between the stations of Aelnensis and typicus ; it occurs fre- 
quently mixed with both forms. S. squalidus typicus, leaves 
irregularly pinnatifid, with lobulated or coarsely toothed lobes ; 
achenes silky. Grows on the lower slopes of Etna. S. squali- 
dus {S. chrysantheniifolius, Poir. S. siculus All.), leaves bi-pin- 
natifid with narrow, nearly linear lobes and lobules, achenes 
silky. Grows on low land in Sicily. The var. glaucescens is a con- 
necting link or a hybrid between Aetimisis and typicus, two well 
distinguished plants. There occur frequently all intermediate 
plants between glaiicescens and the two other species or varieties. 
The var. chrysanthemifolius seems to be only an extreme state 
of typicusP I saw this latter growing in the volcanic dust in the 
Strada Etnensis, and closely allied forms on dry gravel rubble 
near Oxford. I may here record the occurrence of S, squalidus 
at Southall in Middlesex, at Swindon in Wiltshire, and at Verney 
in Bucks. — G. Claridge Druce. 
Cnicus (?). Rough grassy ground about Nash Point, Glamorgan, 
July 1904. In patches sometimes several yards across, and ex- 
tending along at least three or four miles of coast : generally close 
to the cliff edge where the ground has been undisturbed, but 
also in similar ground some little way up one of the small valleys 
leading down to the shore. The thistles of the neighbourhood 
are Carduus pycnocephalus, Linn., C. nutans, Linn., C. crispus, 
Linn., C. nutanti-crispus, Cnicus eriophorus, Roth, C palustris, 
Wind., C. arvensis, Hoffm., and C. acaulis, Willd. The last is 
not widely spread ; it occurs sometimes in the immediate neigh- 
bourhood of the present plant. Probably the plant of Phyt. I. 
780 which was gathered ‘ between St Donat’s and Dunraven ’ 
by Westcombe, and named C. tuberosus, Roth. In Phyt. IV. 519, 
T. B. Flower (1852) wrote that he thought “ Westcombe’s specimens 
could not be referred to C. tuberosus, but would possibly prove 
to be the C. Woodwardii of Mr. Watson, and having lately sub- 
mitted them to that gentleman he arrived at a similar conclusion, 
and writes me : ‘ The plant looks so unlike C. pratensis that I 
do not wonder at the supposition of its being some other species.’ ” 
I have no record of C. p?'atensis occurring nearer than Porthcawl 
Sandhills, a dozen miles away, though I have not thoroughly 
searched all the neighbourhood of Nash Point ; but the dry 
surroundings, and the geological formation of the district (lias
