cellules, which a re o f a roundish figm'e, ai’e d istantly placed, y e t somewliat regula rly,
in longitudina l lines (f. 9 ). T h e color is a pale yellowish b rown, inc lin in g to olive in
th e Scotch variety.
• Perichælial leaves (f. 10) la rg e r th an th e re st, an d prdceeding, as i t appears to me, from
all sides o f th e stem : th e divisions o f these leaves too a re more numerous, frequently
six o r even seven, th e ir ma rgins more recui-ved, th e ir te e th la rg e r and m ore abundant.
In otlier respects they exactly agi'ee w ith th e cauline ones.

Calyx (f. f. 5. 11) nearly a line in len g th , oblong, plicate ; th e m o u th toothed, h u t n o t a t
all co ntra c ted ; th e texture th in and ra th e r delicate, m u ch more so th a n th a t o f th e
leaves ; th e reticulation small ; th e areolæ oblong ; th e color a pale yellow brown.
Calyptra obovate, re ticula ted, white ; style r a th e r sh o rt, slende r, and tu b u la r. T h e
barren pistilla a re numerous, situ a ted a t th e base o f th e ca lyptra : each is linear,
swelling o u t a little in th e middle, its m o u th slightly expanded.
The Capsule I have only seen w itliin th e ca lyptra , a t which period o f its grow th i t is
exactly spherical, and o f a deep olive-green color.
T h a t th e two plants liere figured be long to one and th e same species, I believe th e re will be
ibund no reason to doubt. My v a rie ty fi differs from a. only in b e in g smaller and o f a more
olive-gi’een color, and in hav in g th e segments o f th e leaves entire . T h e d raw ing o f oe I liavc been
u n d e r th e necessity o f m ak in g from fore ign specimens: for th is , I tru s t, no apology will he
considered necessary, as I could n o t otherwise have repre sen ted th e fructification, which is now
described for th e first tim e , th o u g h my description has b e en ta k e n from th e very specimens
g a th e red in Lapland by Linnæus, who, in his own a c count o f th e p lan t, leaves th e fructification
unnotic ed. T h e Lapland specimens, i t may be rema rked, as we ll as th e German, a n d probably
th e F ren ch ones, too, a re foimd in woods, whereas o u r B ritish p lan t inhabits th e h ig h e s t o f th e
Scotch Alps ; an d this difference in th e place o f g row th may pe rhaps be considered as a cause in
some measure o f th e different appearances th ey p u t on. From Dr. Sw a rtz , also, I have been
favored w ith fnictified specimens, exactly ag re e in g w ith those he re figured.
E h rh a rt, who first discovered J . setiformis in th e H a r tz Forest, in Germany, ju s tly remarks
th a t th e leaves are so deeply divided, th a t each imlividual may be ta k e n fo r four separate
leaves: b u t 1 c an n o t ag re e w ith th a t a u th o r in th in k in g th a t th e segments a re so strongly
fuiTowed on th e ba ck as to repre sent in m in ia tu re a le a f o f Fontinalis antipyretica. He fa rth e r
adds, th a t he knoivs o f no o th e r p la n t which ha s such a peculiarity in th e leaf.
T h e re is in th e gen e ra l h a b it o f this p lan t, p a rticula rly in th e mode o f g row th , a considerable
affinity with J . julacea. In bo th tlie leaves a re rig id a n d b rittle , and those, which clothe th e stem
o f th e forme r, correspond v e iy nearly in figure with th e p e richætia l ones o f th e la tte r. T h e form
o f Hic calyx is th e same in bo th , as is also th a t o f th e capsule.
