D e sc e . Boot a minute, scutate disc. Fronds from an inch to an inch and a
half in height, with a distinct filiform stem, about a line in length, at the
summit of which the tube suddenly enlarges and becomes saccate, and then
gradually increases in diameter upwards. When young the frond is a
closed sac; at a later period the apex bursts, the frond then becomes
funnel-shaped, and jagged and plaited at the margin. Substance delicately
membranaceous. Structure cellular; the cells quadrate, something larger
than in B. intestinalis. Colour a pleasant grass-green.
Had not this plant been admitted to the rank of a species by
the late Capt. Carmichael, than whom few naturalists have more
carefully studied this variable genus, I should have been contented
to regard it, with continental authors, as a dwarf variety
of E. intestinalis. Capt, Carmichael says, “ Without pushing
the system of varieties to an extravagant length, this plant
cannot be considered as a variety of E. intestinalis; the characters
of the definition mark it as abundantly distinct, and to
these characters it is universally constant. I look upon it,
