IAIDENHAIE SPLEEKWOET. 
)HIS is a well-known little fern, and a particular favourite with cultivators. 
The fronds make their appearance in April or May, and are persistent through the winter. 
The roots are peculiarly adapted for penetrating into almost invisible fissures in rocks. The 
rhizome is tufted. The stem is short and black, which together with the frond, extends from three 
to nine inches. The frond is pinnate, the pinnae being from a quarter to half an inch in length, 
and oblong. The seed is produced in clusters, which are arranged diagonally to the mid-veins of 
the pinnae. 
f atttat. 
On hedge-rows, walls and rocks, everywhere. 
§mtm. 
There is one marked variety, the pinnae of which are deeply pinnatifid. I have found it near 
Penrice Castle, in Glamorganshire. 
fylkxt 
It is most readily cultivated, requiring no particular directions.

GREEX SPLEEUVOET. 
S HIS species much resembles the last, but is more interesting from its brilliant green colour and 
comparative rarity. 
The fronds, which are evergreen, appear in May or June. 
The roots are delicate and fibrous, the rhizome tufted. The stem is green and about a third as 
long as the frond, the whole length being from two inches to a foot. The frond is pinnate; the 
pinnae are triangular, and notched in the margin. This triangular shape of the pinnae, and the 
brilliant green colour of the stem and frond, form the distinctions between this and A. Trichomanes. 
The seed is produced in clusters similar to the last species.

Generally in moist shady situations; often under the drip of waterfalls. It occurs in the 
Snowdon district, on the Brecon Beacon, at Ysgwd Henrhyd Waterfall, and on the Cribbarth 
Mountain in the Swansea Yalley, and under the Upper Cilhepste Waterfall, in the Yale of Neath. 
I have not met with any. 
Cfllto. 
This species thrives well in greenhouses, if planted in pots or on rockworlc, and well supplied 
with moisture.
