and showy. A native of Southern Europe, where it grows at an alti- 

 tude of 6000 to 7000 feet." H. saxifragura of Fries occurred on the 

 ravine of the White Water and Cairntoul, on mica slate ? and granite ; 

 it is " a handsome species, with rigid or ilexuose stems, bearing 1 or 

 few large heads on elongated peduncles, and having lanceolate toothed 

 root-leaves, narrowed into a short footstalk, and sessile stem-leaves, 

 with few obtuse teeth near the middle. Its involucres have a flat or 

 ovate base and acuminate scales, which are dark with glandular hairs 

 in the lower part." H. pallidum was " abundant on the Clova Moun- 

 tains and Cairn gorum range. Careful comparison of specimens of 

 this with the plant called H. anglicum by Fries, which is also abun- 

 dant in Scotland (.?)," induces the author to doubt their specific dis- 

 tinctness. H. pallidum, var. ? persicifoliuin of Fries, was found on 

 Cairntoul, on granite ; it " appears to be the plant described by Fries 

 under the above-mentioned name, and differs from H. pallidum in its 

 more slender habit, single-flowered or simply bifid stems, and in hav- 

 ing lanceolate, nea.v]y etitire, petiolate Yoot-\esi\es,,few in number, and 

 'perfectly glabrous.'''' H. caesium of Fries, found on the Clova Moun- 

 tains and Cairntoul, on mica slate and granite, " appears to differ from 

 H. murorum in having fewer, smaller and less corymbose heads, a 

 thick ligneous root, more elongated peduncles, and csesious, often 

 nearly glabrous foliage." H. cerinthoides of Fries was found in the 

 gorge of the Eannach and Eagle Crag, near Loch Lee ; at the head 

 of Glen Phee, and in Glen Dole, Clova, on mica slate. " It is dis- 

 tinguished by its tall, rigid, erect stem, bearing 1, 2 or 3 heads on 

 elongated, ascending or spreading peduncles ; by its large, golden- 

 yellow, ciliated ligules ; acute, attenuated, glandular involucral scales, 

 and rather soft, broadly lanceolate, acute root-leaves, which are entire 

 or toothed near the middle, and narrowed into a shaggy dilated foot- 

 stalk ; also by its few (generally 2), ovate, acute, amplexicaul or semi- 

 amplexicaul stem-leaves frequently dilated at the base." The author 

 thinks there is no doubt that this is the H. cerinthoides of Don. 

 " At first sight this plant looks diff'erent from the Teesdale H. Iricura, 

 Fries, and is really very diff'erent from that plant when growing in 

 rich basaltic soil : nevertheless the form of H. Iricum on the lime- 

 stone cliffs is not (?) distinguishable from the Scotch H. cerinthoides. 

 We therefore conclude that B. Iricum is onlv a luxuriant form of H. 

 cerinthoides. The amplexicaul or semi-amplexicaul stem-leaves, lax 

 outer involucral scales, and acute or subobtuse inner scales, appear to 

 occur in both forms." H. corymbosum of Fries, found on heathy hil- 

 locks one mile south of the Kirktown of Clova, is " readily distin- 

 guished from II. crocatum, Fries, by its broader leaves and large,
