3G2 THE CRYPTOGAMIC FLOEA OF KENT. 



Sutlieiiaud southward to Herefordshire. I have never seen it in 

 the low country of the South of England, where muroriLm and 

 vuhjatum are not infrequent. 



H. ccDsiiim, var. cambricum.. — Whole iDlant 1-1^ foot high. 

 Developed leaves 4-5 in a radical rosette cotemporary with the 

 flowers ; hlade thin in texture, as glaucous as in pallidum or 

 ar<ienteum, lanceolate, acute, at most an inch broad, including the 

 very large (\-^ inch) teeth, narrowed to the base, nearly glabrous ; 

 petiole shorter than the blade, nearly glabrous. Stem without any 

 leaves or bearing only a single small one near the base ; heads 3-4, 

 all on longish peduncles, thinly coated upwards with wdiite stellate 

 down ; black bristly hairs nearly absent. Involucre finally i— | in. 

 diameter, ^ in. long ; i^hyllaries linear, tapering to an acute pomt, 

 matted with a httle white stellate tomentum down the edge, the 

 outer ones nearly all black, the inner with a black keel and 

 greenish margin ; black bristly hairs short and not gland-tipped. 

 Styles not seen in the living plant. Flowers not quite an inch 

 long. Great Ormes Head, on limestone rocks. 



H. luiirorum, of Backhouse, and Engl. Bot., edit, iii., tab. 846, 

 has thin rosette-leaves suddenly narrowed at the base, usually one 

 large distinctly-petioled leaf placed some distance above the base of 

 the stem, more numerous much smaller heads than in cccsium 

 SinitJiii, the central heads of the corymb on very short peduncles, 

 and the black-based hairs of the involucre and top of the i^eduncles 

 furnished with abundant ghinds. H. stelUgerum of Backhouse 

 [H. jiocculosum, Engl. Bot., edit, iii., tab. 848), which Fries cites 

 imder casium as a mere synonym, not even as a variety, has heads 

 like those of casiwii Smithii, but differs by having mostly two 

 large stem-leaves, and is a more robust plant than the Scan- 

 dinavian cccsium, with leaves hoary on both sides with thin white 

 stellate down. If we look upon the three forms above described 

 as varieties of one species, we must place jiocculusum as a fourth.
