2. Alpine Poltpodt (Polypodmm Alpestre). Pl. 5. 



The fronds of this fern vary from twelve to eighteen inches 

 in length. They spring from a thick tufted rhizome, and are 

 spear-shaped and bi-pinnate : the pinnules are deeply lohea, and 

 the edges are serrated. The sori are circular and without 

 indusia, situated on either side of the midrib of the pinnules. 

 It is only found in the Highlands of Scotland. It may be 

 grown out of doors in a shady situation, and in loose peaty 

 soil. It somewhat resembles the Lady Fern in general appear- 

 ance. It is termed FseudMhyrimm Alpestre by Newman. 



3. Limestone Poltpodt {Polypodium Calcarevm). Pl. 5. 



Each frond of this fern has three branches, one being k 

 continuation of the Stem, and the others diverging from it on 

 either side, very nearly at right angles. The pinnae of the 

 branches are deeply lobed or pinnatifid, and the sori are placed 

 close together along the edge of the under part of the leaflet. 

 It is of a dark green colour, and the fronds are covered with 

 minute glands on fine stems, which give it a powdery appear- 

 ance. It is found in the limestone districts of the northern 

 counties of England. It must be kept dry, and grown in 

 common soil, mixed with hme and rubbish. 



4. Oak Febn {Poh/podium Dryopteris). Pl. 5. 



A fern very simila* to the Limestone Polypody in general 

 character and length of the frond, which is from four to 

 fourteen inches. The stipes is slender, purple, and scaly at the 

 base. The lobes of the pinnse are not so deeply cut, but 

 blunted at the point; the sori are placed at intervals along 

 their edges. It is found in moist situations in the north of 

 England, Wales, and Scotland. It may be gi-own in common 

 soil, and is well suited for rockwork. It requires shade, and 

 frequent watering, but the roots should be kept well drained. 



6. Beech Eehn (Polypodmm, Phegopteris). Pl. 5. 

 A fern with fronds pinnate at the base, and pinnatifid 

 towards the extremity. The stipes is very long, in proportion 

 to the entire length of the frond from the rhizome, which 

 (■aries from five to twelve inches. The lower pinnse droop 

 towards the stipes, the rest turn upwards. The littlo naked
