simple, growing 9 inches high; heart-shaped at the base, but 

 lengthened-out above and rooting at the point. 



ASPLENIUM. 



There are no less than twenty-two 

 species of this genus that require green- 

 house treatment. Some certainly grow 

 more freely in a stove, and others will 

 exist in the open air A. marinum, for 

 instance ; but the more tender ones may 

 be placed in the warmest part of the 

 house, and the others in the coolest. 



ASPLENIUM ,APPENDICULATUM (Ap- 

 pendaged). A Fern from Van Diemens 

 Land, of great beauty. Fronds tripin- 

 nate, a foot high, or more, and rooting 

 at the extreme point ; pinnsc or leaflets 

 oval-shaped, sharply cut into segments 

 at the edge. Spore-masses oblong, 

 covering the under surface of the fronds. 

 Stalks scaly and winged. Rootstock 

 creeping, but slowly increased by divi- 

 sion, and the rootbulbs formed at the 

 ends of the fronds. This is now

phyiia. (Froud natural generally looked upon as one of the 

 many forms of A. lulbiferum. As 



several species propagate themselves by these self-formed 

 appendages, we may just as well describe for all how to 

 manage these proliferous fronds. When the tufty bulb or 

 knob has become of a moderate size, fill a small pot with 

 the proper compost, and place it so near the proliferous frond 

 as to allow the end just to reach the centre of the pot. Then 

 either peg it down with a hooked stick, or lay a small stone 

 upon the frond, just behind the knob, pressing it down close
