become luxuriant, assuming the appearance of T. pyxidiferum , and never 
bearing fructifications. GrifF. Capsules two-valved, furnished with an

Its habit, as represented by Mr. Bolton, is considerably different from that 
in E. Bot. and though the latter has indeed fruit-stalks springing from 
the mid-rib, they are not naked, but pass within the substance to the 
edge of the leaf.

As this rare plant has hitherto been but imperfectly understood, we tran¬ 
scribe the very elaborate description of Dr. Hooker. 
Caudex creeping, the thickness of a sparrow’s quill, clothed here and there 
with thick, downy roots. Stipe two to four inches long, flexuose, 
with a membranous margin. Frond four inches to a span high, ovato- 
lanceolate, triplicato-pinnatifid. The primary pinnae three inches long, 
the upper ones gradually shorter; and those as well as the secondary 
ones ovato-lanceolate, with the lacineae linear, undivided, emarginate, 
or bifid, and the margins entire; furnished with a slender brown nerve 
or mid-rib, prominent on both sides, and running through the middle. 
Rachis winged with a broad foliaceous margin. The substance of the 
frond is membranous, smooth, beautifully reticulated, with roundish 
areolie. Colour brownish green. Involucres in the axils of the pinnulae, 
solitary, of one leaf, oblongo-turbinate, between carnose and membra¬ 
nous, not serrated, but slightly notched on one side; the sides winged. 
Receptacle in the centre of the involucre, filiform, exserted. Capsules 
rounded, sessile, fixed by the disk, compressed, brown, collected toge¬ 
ther near the middle of the receptacle, their disk reticulated, the elastic 
ring large. Seeds round.

head of a remarkable spring, as recorded by Dillenius in Ray Syn. 
Found there also by Mr. Teesdale, in 1782, but has been since extir¬ 
pated, according to Hailstone in Whitaker’s Craven. In Ireland it is
