ALPINE FLORA AND FERNS OF NORWAY. 295 



the birch-limit. Eare. 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. BOREALE (Fries), with lanceolate -tooth leaves; (3 latifolixm 

 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, 3 to 5 ; not so 

 downy as in H. BOEEALE, but sparsely furnished with short stiff 

 glandular hairs. Most probably the latter is a distinct species. 

 Both are found in low scrub by Drivstuen and other places in 

 Drivdal. The last-named reaches up to the birch-limit. 



H. CORYMBOSUM (Fries). Places in Drivdal. Resembles H. 



BOREALE. 



H. CROCATUM (Fries). As the last. 



H. UMBELLATUM, L. ; FL D. tab. 680. In low scrub by 

 Drivstuen and other places in Drivdal. Not found above the 

 birch-limit. 



H. PALUDOSUM, L. ; Fl. D. tab. 928. By Foystuen and in 

 Drivdal up to the birch-limit. Found in moist places in meadows. 

 Leaves smooth and thin. 



HYPOCH^RIS MACULATA, 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, /3 asperior uniflora 

 (Wahlberg), Fl. D. tab. 1,523, very similar to it, is found up to 

 and above the birch-limit. 



CAMPANULACE.E. 



CAMPANULA UNIFLOHA, L. ; Fl. D. tab. 1,512. Plentiful in 

 some places on Knudshoe, near Kongsvdd, and on the Fjeld by 

 Drivstuen; less common on Gederyggen, near Jerkin. On 

 Knudshoe it is found above the birch-limit on dry places which 

 abound in lichens, such as Cetraria nivalis, cucullata, islandica ; 

 Carnicularia ochroleuca, and Cladonia ranyif"rina, &c. It appa- 

 rently vanishes below the lasting snowdrifts. 



C. ROTUKDIFOLIA, L. ; Fl. D. tab. 1,086. Common over the
