ATHYRIUM FILIX-FCEMINA 107 
and also Ше plumose type, indicates Ше possibility that the Oxford 
parent might have arisen from the original Irish find, though of 
course this can only be surmised. 
К. CRISTATUM.—A remarkably pretty, but so far small, crested 
form, raised quite accidentally by the writer, several years after 
vain attempts at a cross. The prothallus bore no less than seven 
plants, six of which survived separation. All are exactly alike, true 
Kalothrix, plus crests, and with the same tendency to slight partial 
reversion. 
К. FOLIOSUM.—Divisions wider than in Kalothrix, and when it 
reverts, it does so to the normal. 
K. LINEARIS.—A distinct form raised Бу Н. Stansfield; SUD 
divisions longer. 
К. PLUMOSUM.— This is the plumose form above referred to as 
raised from Kalothrix by Messrs. Stansfield. 
LACINIATUM.—Very fine divisions. 
L. ELEGANS, L. RAMULOSUM.—These are crosses made by Messrs. 
Stansfield between Craigii and the Horsfall plumosum; elegans 
has cruciate pinnules and no crests, but ramulosum is practically 
a multifid Horsfall. 
LAXO-CRISTATUM.— Found by W. H. Phillips in Co. Down ; long 
lax pinnules, crests small. 
LuNuLATUM.—A synonym for Frizellie. 
MAGNI-CAPITATUM.—Raised by Stansfield from acrocladon ; 
fronds flat, but otherwise branched like parent; а splendid 
form. 
MEDIO - DEFICIENS (ABASILOBUM). — 
Characterized by abortion, partial or 
entire, of subdivisions adjacent to mid- 
ribs of frond and pinn&, an open space 
being thus left. In a form found by 
the writer, near Wigton, N.B., this is 
so regular even in the pinne that the 
Fern is very pretty, but as a rule it 5 
is irregular in the many finds so named, 25 
and hence they are of little value. 
M. CAUDICULATUM.—Found in Ireland 
by W. H. Phillips. Besides the above 
character, the tips of the pinne run out 
into inch-long even tails, prettily set 
with bristles. 
MESEMBRYANTHEMOIDES (Fig. 86).— 
Found by Mr. Clapham ; a dwarf form, 
with heavy bunch crest to frond. A small 
grandiceps.
