448 THE FOREST FLORA OF CARNARVONSHIRE. [April 



*P. angulare. Not uncommon and usually associated with P. aculeatum. 

 In one or two stations it, however, grows alone, such as 

 alongside a woodland ditch between our home nursery and 

 Bishop's mill. 



Lastrca Orcopteris. Very common from 300 feet upwards. Plentiful 

 in several woods near Dolawen farm, Bethesda. It also occurs 

 in some plenty within a few hundred yards of the sea at Capel 

 Ogwen. 



L. Filix-mas. Everywhere abundant as a woodland plant. 



*L. Filix-mas. var.pumila. Eare, but I have found it on one or two 

 occasions on high elevations. 



*L. Filix-mas. var. intcrrupta. This curious and distinct form I 

 have met in with in one of our woods. Specimens trans- 

 ferred to my garden retain their distinct character under the 

 best cultivation. 



*Z. Filix-mas. var. palacea. Not uncommon in the woods in Pen- 

 rhyu Park. 



L. dilatata. A common occupant of the woods and plantations in 

 this county. I have found various distinct and well-marked 

 forms. 



*Z. spimdosa. Plentiful in an old wood at Ogwen Bank. This is 

 the only place I have seen it growing. 



*L. riffida. This rare plant I have found on one occasion, and, 

 strange to say, in soil destitute of lime. The position in which 

 I found the plants precludes the possibility of their having 

 been introduced. 



Athyrium Filix-fcemina. Freely distributed in most woods. 



*A. Filix-foemina var. depavpcratum. Eare. I have found it on two 

 occasions. 



'"'A. Filix-famina var. fiuduosa. A few specimens of this rare and 

 interesting form occur in a wood on the banks of the Ogwen 

 river, near Half-way-house. 



*A. Filix-fccmina var. furcata. Occasionally I have found this rather 

 interesting form. 



Asplenium- marinum-. A few specimens are found on the Great Orme's 

 Head. Some years ago it existed amongst the bushes and 

 trees that cover the rocks in front of the University College 

 at Bangor; but the too pressing attention of botanists has 

 caused it to become extinct in that locality. 



A. Trichomancs. Abundant on old woodland walls. 



A. viride. Eare as a woodland plant, but freely distributed in moun- 

 tain situations. 



A. Adiantum-iwjrum. Plentiful on old banks, walls, and fences of 

 woods and plantations.
