PINDEE S FERN. 



FINDER'S FERN. 



Genus. — Lophodium. (See page 130). 



Species. — Collinum. Caudex tufted; crown broad, dark- 

 coloured : fronds symmetrically arranged round a centre, but 

 not numerous : stipes notably shorter than the frond, clothed 

 at the base with lanceolate scales, which are dark-coloured, 

 with still darker apices : fronds pinnate : pinnee pinnate : pin- 

 nules serrated, the teeth scarcely mucronate ; under surface 

 glandular : clusters of capsules scattered, rather small, distri- 

 buted over the entire under surface : involucre jagged at the 

 margin, and fringed more or less with stalked glands. 



Lastrea multiflora, var. collina, Newm. F. 233. 



Lastrea dilatata, $. collina, Moore, 123. 



Lastrea collina, Moore, 128. 



I think it possible, but extremely difficult to j)rove, that 

 this plant is the Polj'podium tanacetifolium of Hoffmann, in 

 ' Deutschlands Flora,' ii. 8 ; and the Polystichum tanacetifo- 

 lium of Lamai'ck and DeCandoUe, ' Flore Frangaise,' ii. 562. 



Beyond the limits of Britain I know nothing of this fern. 



In England, it occurs in the Lake district of Lancashii-e and 

 Westmoreland, and in Yorkshire ; and I am indebted to the 

 Eev. Mr. Finder, and to Miss Beever for specimens, and for all 

 the information I possess respecting the species.
