ALPINE FLORA AND FERNS OF NORWAY. 295 
the birch-limit. Rare. More plentiful in low scrub near Driv- 
stuen. Stalk many leaved, hairy. Leaves slightly toothed, and 
hairy beneath and on the edges. Flowers, 7 to 8. 
H. Boreazez (Fries), with lanceolate-tooth leaves; 8 latifoliz:m 
with cordate, sub-amplexicaule leaves. The latter of these two 
forms is very marked, and may be distinguished from the former 
by its smaller development (rarely 1 foot high), by the stalk- 
leaves being fewer (usually 3 to 4), and wider apart; by its ovate- 
lanceolate root-leaves, broader stalk-leaves, cordate, toothed, and 
often marked with brown spots. Flower heads, 8 to 5; not so 
downy as in H. BorEALE, but sparsely furnished with short stiff 
glandular hairs. Most probably the latter is a distinct species. 
Both are found in low scrub by Drivstwen and other places in 
Drivdal. The last-named reaches up to the birch-limit. 
H. corymposum (Fries)—Places in Drivdal. Resembles H. 
BOREALE. . 
H. crocatum (Fries).—As the last. 
H. umpetyatum, L.; Fl D. tab. 680.—In low scrub by 
Drivstuen and other places in Drivdal. Not found above the 
birch-limit. 
H. patuposum, L.; Fl. D. tab. 928.—By oystwen and in 
Drivdal up to the birch-limit. Found in moist places in meadows. 
Leaves smooth and thin. 
Hypocu#ris MacunaTa, L.; Fl. D. tab. 249.—By Bergsgaard, 
and on hills near Tofte, where it vanishes a little below the birch- 
limit. 
APARGIA AUTUMNALIS (Willdenow), Fl. D. tab. 1,996.—Ge- 
neral over the whole Fjeld. A variety, 8 asperior uniflora 
(Wahlberg), Fl. D. tab. 1,523, very similar to it, is found up to 
and above the birch-limit. 
CAMPANULACEZ. 
CAMPANULA UNIFLORA, L.; Fl. D. tab. 1,512.—Plentiful in 
some places on Knudshoé, near Kongsvold, and on the Fjeld by 
Drivstuen; less common on Gederyggen, near Jerkin. On 
Knudshoé it is found above the birch-limit on dry places which 
abound in lichens, such as Cetraria nivalis, cucullata, islandica ; 
Cornicularia ochroleuca, and Cladonia rangiferina, &e. It appa- 
rently vanishes below the lasting snowdrilfts. 
C. notunpIFoLIA, L.; Fl. D. tab. 1,086—Common over the
