30. H. rigidum Hartm. ? ( rigid-stemmed H.) ; stem rigid 
with a leafy branched corymbose panicle, leaves dull green 
paler or subglaucous beneath 3-nerved ovate- or oblong-lan- 
ceolate few toothed about the middle lowest ones attenuated 
into winged petioles upper narrowed to a more or less am- 
plexicaui or rounded base sessile, involucre after flowering 
conical and not constricted in the middle uniformly dark or 
blackish green with scattered hairs and setae, scales adpressed 
obtuse, ligules glabrous. 
Mountainous districts. Upper Teesdale. Co. Antrim. Clova. 
8, 9 With this species we are scarcely acquainted. “ Styles 
yellow or rather lurid with dark hairs.” — Backhouse. 
31. H. corymbosum Fries {corymbose Id.) ; stem rigid with a 
spreading leafy branched corymbose panicle, leaves loosely re- 
tculated glaucous and floccose beneath rather hairy on both 
sides ovato-lanceolate irregularly toothed sessile with an am- 
plexicaul or rounded base, peduncles scaly, involucre subglo- 
bose in bud afterwards ovate or truncate at the base with 
scattered hairs and setas, scales adpressed inner obtuse, ligules 
glabrous. 
Mountain glens ; rare. Banks of the Clunie, near the Castletown 
of Braemar. If.. 7, 8. — If we mistake not, the species as now limited 
!>y Mr. Backhouse excludes part of what we. on the authority of Mr. 
Baker, referred to it in our last edition. Mr. Baker compared it with 
“ H. crocatum, but distinguished by its leaves, panicles, and invo- 
lucres;” adding that it was to be found in Teesdale and Wales, 
besides Scotland. Mr. Backhouse knows of one locality only, and 
compares it with H. rigidum, and seems only to admit it as a species 
upon the authority of Fries. So gradually do these supposed species 
pass into each other, that scarcely two botanists can give the same name 
to a specimen which departs slightly from what each chooses to consider 
the typical form. 
32. H. boreale Fries {shrubby broad-leaved H.) ; stem rough 
or hairy with a panicled or racemose leafy corymb, leaves dull 
green paler beneath 3-nerved toothed or denticulate lower 
ones lanceolate or ovate-lanceolate narrowed into a villous pe- 
tiole, upper sessile ovate with a broad rounded or cordate base, 
peduncles copiously floccose scaly erect or ascending, involucre 
ovate at the base uniformly dark-green or blackish, scales ad- 
pressed glabrous or sprinkled with longish brittle hairs inner- 
most very blunt outer often narrower, ligules glabrous at the 
apex, styles livid or dark. Ii. sabaudum E. B. t. 349. 
Woods, hedges, and railway embankments, not uncommon. If. . 7 — 
10. — We fear that this is merely one of the many forms of one very 
variable species; and that as it agrees in most points with several 
others of the section, the characters ought to be altered to include 
them. The form or species usually called by the present name is 
described above, and is best known by the dark involucre, without 
down, contrasting with the white downy peduncles.
