ceolate attenuated below, stem 1. sessile, upper I. ovate half clasp- 
ing, involucre covered with long silky hairs : scales attenuate 
from an ovate base outer ones lax. — L. st. and involucres with 
long silky yellowish hairs, mixed on the peduncles only, with 
stellate pubescence. St. simple or divided, with erect peduncles, 
and several leaves. //. villosum E. B. is a cultivated state of 
H. alpbmm /3. but the true plant is in Smith's Herb. — " Rocks 
near Loch Callater, north of Clova. Mr. T. Drummond." Sm.

7. II. mtirorum (L.) ; st. bearing a single leaf, radical I. nume- 
rous persistent ovate or cordate with retrofiexed teeth at the base 
rounded obtuse or attenuated at the extremity hairy beneath 
stalked, heads corymbose, involucre pubescent. — E. B. 2082. — 
St. erect, 12 — 18 in. high, nearly naked. Branches of the 
corymb bent. This species and the 2 following are so closely 
allied that it would probably be better to consider them only as 
forms of one very variable species, but that must be determined 
by further observation. My friend Mr. J. Ball is preparing a 
paper upon this genus which will probably throw light upon 
these plants, and in the mean time I have thought it better 
almost exactly to follow Fries. — Rocks, walls and woods. P.

8. H. diaphanum (Fries) ; st. bearing 1 or 2 leaves, radical I. 
numerous persistent ovate-lanceolate narrowed into a footstalk 
entire and denticulate or with teeth all pointing forwards, st. 
simply branched or somewhat corymbose. — cc. pulmonarium ; st. 
subcorymbose, heads rather small, 1. ovate-lanceolate, stem 1. 
similar but smaller. " H. pulmonarium Sm." Fr., but Smith's 
specimen figured at E. B. 2307. appears different. — fi. Lawsoni 
(Fr.) ; st. forked with straight peduncles, heads larger, 1. lanceo- 
late or elliptical, stem 1. much smaller. H. Lawsoni Sm. E. B. 
2083. H. Halleri Hook. Lond. 215. This var. varies with 
elliptical entire denticulate 1. or with them lanceolate and den- 
ticulate or with a few teeth ; the petioles are variable in length 
but usually very silky. Fl. large cream-coloured. Distinguished 
from H. murorum by the 1. narrowing downwards and their teeth, 
when present, ascending ; from H. sylvaticum by its numerous 
radical and few stem 1. and by habit in which it agrees with the 
preceding. Varying greatly in size and pubescence. — Moun- 
tainous countries. P. VII. 
9. H. sylvaticum (Sm.) ; st. with several I., radical 1. few per- 
sistent, all oblong-lanceolate narrowed into a footstalk usually 
coarsely toothed teeth all pointing upwards, heads panicled, invo- 
lucre pubescent — E. B. 2031. H. vulgatum Fr. — St. erect, 
leafy. True radical leaves 0 (?) but several 1. closely placed near 
to the bottom of the stem ; uppermost stem 1. nearly or quite 
sessile but of the same form as the others. — /3. maculatitm
