THE COMMON HARTS-TONGUE FERN 
prone to send out a midsummer shoot, which is common to all Ferns in a slight degree ; but this 
occasionally produces a young stipitate frond from the apex of the larg 
ne, ita stipe 
being thickly 
clothed with scales as in the lower or parental portion. It was found by Mr. Wollast 
48. undulatum (ML). This is regularly wavy-curled like 
ın in Dorsetshire 
ispum (46), but somewhat less so, and is 
narrower, and unlike that, fertile. А lobed variation of it, an old garden plant—undutato-dobatum 
has been recently found in Sussex by Mr. Wollast 
Tho typical stato of this variety is often 
confounded with crispum, and is а constant plant, not uncommon. 
49. complicatwn (W.) was found wild in 1853 in private grounds at Chislehurst, Kent, by Mr 
Wollaston. The f 
mds are either simple or multi, 
and their margins are irregularly ere 
ate, 
laciniate, and undulate ; in some respects it approaches undulatum, Tt is an unusual form. 
50. conjunctum (M). А very pretty form, found by Mr. James in Guerns 
It is dwarf, broad, 
undulated, 1 
and the apices of the lobes are multi, with 0

sagittifolium (УУ. is remarkable for having the auricled portion of the lower part of the frond

ated and deflexed, as the barbs of an arrow, each with а distinct midrib, The plant has a tendeney 
to be multifid both at the apex of the frond and also at the elongated auricles, It was found in Sussex 
by Mr. Wollaston in 185 
and is doubtless a constant form, as the fronds of the former year had the same 
peculiarity. Others very similar have been found in Ireland by Dr. Allchin, in 1853, in the counties 
Clare and Kerry. It is not the var. sagittatum of Willdenow, a dwarf South of Europe plant 
52. retinereinm (N). The netted venation is the chief peculiarity of this variety. Тіс fronds are 
unevenly strap-shaped, sub-multifid, and blotched with whitish-green, almost amounting to variegation, 
Tho margin is entire but uneven, It was found in Ireland by Dr. Allchin in 1853, and is unique. 
dissimile (W.) was found by Mr. A. Clapham near Settle, in Yorkshire, in 1855, and, as its name 
implies, has the fronds so unlike each other that they seem to belong to different plants; some are 
multiid, sinuate ; others interrupted and laciniate, and some again truncate, obtuse, fan-shaped, It 
vigorous growing form. 
54. depauperatum (W.). A most curious deforn 
iy. Instead of fronds, the plant has little else but 
their midribs, forming subulate points, either simple, bifid, or multi, And as if instinct were given 
it, and that it felt it could not exist without spiracles it throws up, in the course of the season, one or

55. multifidum (W.) includes all forms from the simply 
those which are more complicated, but in which the lower portion of the frond is normal, and which 
aro neither uniformly affected, nor uniformly permanent. ‘The sub-forms are numerous, 
furcatum (УУ). A very rare variety. Its character consists 
exactly down the midvein, each portion falling back, forming the shape of a bird's claw ; these occa- 
sionally grow on as in other multifid forms, and divide exactly in the samo way over and over again, 
while the lower portion continues normal, 
57. cristatum (Clapham) is closely allied to crista-galli (58) and also to ramosum (63)—to the former, in 
the plication of the apex, although it is not nearly so much erisped, and to the latter in general habit and 
the frond on the 
taney. Tt also has a curious inclination to produce frilled cups on the under side o 
main rachis, an inch or two from the apex. The frond is normal in its lower parts. It was found by 
А. Clapham, Esq, near Settle, in Yorkshire, and is rare 
58, erista-galli (W) is one of the modifications of multifidum, but differs from it in the apex being 
‘a complicated folding rather than a complicated dividing of its parts. The lower portion of the frond 
is erenato-undulate. It is permanent under cultivation, and produces the same form from its spores. 
It was found in Dorsetshire in 1850 by Mr. Wollaston. 
59. chelafrons (W.). This curious little plant, evidently of the multifid group, is, from its pigmy 
habit, scarcely to be distinguished as such. The fronds rarely attain a length of four inches, but are 
more frequently from half an inch to two inches long; the apex of most of them is bifurcate, exactly in
