cauline shortly stalked or subsessile upper sessile passing 
gradually into bracteas, peduncles ascending rigid, involucre 
dark green with black-based hairs and scarcely any stellate 
down, scales broad obtuse spirally imbricated, florets glabrous, 
styles yellow or with minute livid hairs. — a. stein with scat- 
tered hairs or nearly glabrous, radical leaves usually withering 
before the heads expand, styles more or less livid. — /J. stems 
purplish red rather hairy, radical leaves usually persistent, 
cauline ones broadly ovato-lanceolate, styles yellow. H. Nor- 
vegicum Fr. ? 
Heathy or grassy places in sub-alpine districts. — a. Teesdale; Cader- 
Idris ; Snowdon ; Llanberis. Connemara ; Carrickfergus. Clova ; 
Braemar. — /3. Kirk-town of Clova. If.. 7 — 9. — Leaves all similar in 
form. This species approaches to II. sylvaticum, with which it accords 
in the radical leaves being either persistent or evanescent ; it agrees 
also in the glabrous ligules and sometimes livid styles, but differs in 
the obtuse scales of the involucre. 
24. H* Dovrense Fr. ( Dofrine //.) ; “pale green, stem 
simple leafy divided upwards into few short 1- (or rarely 2-) 
headed peduncles, leaves oblong or lanceolate toothed, radical 
ones smaller than the others stalks soon withering, cauline ones 
sessile, upper with a cordate base and semi-amplexicaul, 
involucre becoming black hairy, scales broad obtuse, ligules 
ciliate.” — Fries . 
Scotland (Fries). If.. 7,8. — We have seen no British specimens ; 
from the radical leaves soon withering, it, as well as the last, might be 
supposed to belong to the next group ; it has an involucre similar to 
what we find in H. boreale and its allies, but the ligules appear to he 
constantly ciliate. Leaves passing gradually into bracteas. Invo- 
lucre subglobose, pretty large, black, with a few short simple hairs or 
rarely black setae. Achenes as in LI. boreale, dark-brown, slightly 
scabrous ; pappus white. Styles fuliginose when dry. 
C. 1 Plants producing (in autumn) closed leaf-buds at the base 
of the stem, which next year become leafy stems without 
true radical leaves. Scales of involucre in many rows. 
Achenes of moderate size, truncate at the top; hairs of 
pappus unequal. Accipilrina. (Sp. 25—32.) 
25. H. tridentdtum Fries (straight- scaled shrubby II ) ; stem 
rigid or flexuose sub-corymbose or panicled at the top, leaves 
1 In this group the leaves are said to be loosely reticulated when the nerves 
given off by the midrib soon branch and disappear among the veins ; and 3 -nerved, 
when these nerves retain their appearance curving upwards towards the margin, 
and there usually uniting with those below and above them to form a nerve pa- 
rallel to the margin. 
a. Leaves green, narrow , with a few teeth at the middle. Involucre of fruit con- 
stricted at the middle. Ligules glabrous. 
25. H. tridentatum Fr. ; heads corymbose, styles livid, leaves 3-nerved.
