THE PERN FAMILIES OF BRITAIN. 
A. A.-u. caudifolium (tailed-fronded). This is a very 
curious form, "both frond and pinnae ending in long tails, and 
bearing blunt lobes, of a yellow colour, which impart a strange 
appearance to the plant. This was a wild find on Dartmoor, 
where some hundreds of plants of it covered a stone wall. 
A. A.-n. cristatnm (crested). Neatly crested. 
A. A.-n. grandiceps (large-crested). See Plate II., 10, and 
Fig. 18. This was found growing on an old wall in Co. Water- 
ford, Ireland, and has heavy, fan-shaped crests and fan-shaped 
pinnae. It is a very pretty plant when well grown. An 
equally fine form, with crest and pinnae more deeply cut, was 
found subsequently in North Devon. Our illustrations re- 
present the Irish find. 
A. A.-n. microdon (small-toothed). A very bold-growing 
form, with large pinnae hardly subdivided; very distinct. 
The Lanceolate Spleenwort 
{Asplenium lanceolatum). 
This very much resembles the Black Maidenhair Spleenwort, 
but the stalks are lighter coloured, and the leafy part of the 
frond spear or lance shaped — whence the name. Spore-heaps 
typical of the family. While there are fronds in process 
of unfolding, this Fern can easily be discriminated from the 
preceding species by the divisions keeping their tips tightly 
rolled up as long as possible, instead of loosening out at a 
much earlier stage. This is a true wall Fern, and needs 
corresponding culture. Until very recently there was no 
crested variety, but at length it has come to light. 
A. 1. cristatum (crested). Recent wild find, and still 
young, but heavily and symmetrically crested on tips of frond 
and pinnae. 
A. 1. microdon (small-toothed). Same sport as the micro- 
don of A. Adiantum-nigrum, which it very closely resembles. 
The Sea Spleenwort 
{Asplenium marinum). 
This handsome Fern has thick, leathery fronds, only once 
divided, the pinnae bluntly saw-toothed; the fronds are narrow
