limit. Bears fruit the summer through, and found with ripe 
fruit from autumn to spring. 
P. Poecorreris, L.; Fl. D. tab. 1,241.—In woods. Common 
up to Alten and Hammerfest ; probably also in East Finmark. 
Grows on the mountains up to and above the birch-limit, 
end is found even at higher altitudes than the last. Bears 
fruit all the summer. Occasional in Drivdal and Vaarstien. A 
variety, P. major, has been found on Bogstadaas, near Chris- 
tiania. 
P. Dryorreris, L.; Fl. D. tab. 1,943—Common in shady 
places in forests up to East Finmark; on the mountains up to, 
and sometimes above, the birch-limit. Bears fruit from the be- 
ginning of the summer to August and September, according to 
the altitude. Grows in Drivdal up to and above the fir-limit. A 
variety, P. tenerrimum, of much more delicate growth, has been 
found on Grefsenaas, near Christiania. 
P. nHa@ticum, L.; Fl. D. tab. 2,607.—Common on the 
mountains from the southernmost part of Christiansand Stift 
(e. g.. on Hekfjeld) to East Finmark, where it descends to the . 
sea-shore. In the south it is only found in the higher regions, 
scarcely under the limit of fir, and grows at altitudes of 4,000 
feet above the sea. The nature of the subsoil does not seem to 
affect it. 
P. Ropertianum, Hoff.; Suppl. Fl. D. tab. 41.—Has a great 
resemblance to the last. Occasional in shady places from 
Porsgrund and Christiania to Snaasen in Throndhjems Stift. 
Professor Blytt remarks that he has never found it on the 
mountains, and scarcely at higher altitudes than 1,000 feet. Bears 
fruit from June to August and September. Grows always on 
chalky soil. 
Woopsta ILVENsISs, R. Br.; Fl. D. tab. 391 and 2,186.— 
Common in fissures in the rock from the southern parts of Chris- 
tiansand Stift to East Finmark ; on the mountains in osier copses 
up to and above the birch-limit. Grows in the lower part of 
Drivdal in the region of fir. Bears fruit at different times, ac- 
cording to altitude. 
W. Hyperporea, R. Br., FL D. tab. 2,185.—Bears a great re- 
semblance to the last. Habitat same as the last. Occasional in 
Drivdal, and more frequent than the last. It seems to thrive 
best on substrata of lime and slate,
