THE FLORA OF MOUNT RAINIER 



Picea engelmanni Parry. Engelmann Spruce. 



Rather a rare tree about Mount Rainier, at 3,500 feet elevation. 

 In the Sitka or Tideland spruce the leaves are decidedly flattened ; 

 in the Engelmann spruce they are nearly square in cross section. 



ISOETACEAE. (Quillwort Family.) 



Isoetes echinospora braunii Engelmann. 



Common in the small lakes near the foot of Pinnacle Peak. 



LYCOPODIACEAE. (Club-moss Family.) 



Lycopodium annotinum Linnaeus. 



A large patch of this handsome species occurs at the point where 

 the trail first crosses Paradise River above Longmire Springs. 



Lycopodium sitchense Ruprecht. 



Common on the meadows at 4,000 feet elevation. 



EQTJISETACEAE. (Horsetail Family.) 



Equisetum limosum Linnaeus. 



This species occurs in the bog on top of the ridge above the foot 

 of Nisqually Glacier. The old trail to the park led through this 

 bog. 



Equisetum arvense Linnaeus. 



Sterile fronds of this plant were observed at Longmire Springs. 



Equisetum robustum A. Braun. 



Common in damp places up to 3,000 feet elevation. Readily 

 eaten by cayuses. 



POLYPODIACEAE. (Fern Family.) 



Polypodium hesperium Maxon. 



Not rare in rock crevices on the cliffs overlooking the lakes at 

 the foot of Pinnacle Peak. 



Phegopteris dryopteris (Linnaeus) Fee. 



The pretty " oak-fern " is abundant along the trail above 

 Longmire's, in deep woods. 



Phegopteris alpestris (Hoppe) Mettenius. 



Forming crown-like tufts in the talus at the foot of cliffs in 

 Paradise Park. 



Dryopteris spinulosa dilatata (Hoffman) Underwood. 



The common wood-fern is frequent in the forests at 3,000 feet 

 altitude. 



Polystichum lonchitis (Linnaeus) Roth. 



Specimens of this species are in my possession from Mount 

 Rainier, but the exact place of collection has passed my recollection. 

 Presumably it was found in or near Paradise Park.
