ENTEROMORPHA CORNUCOPLA, Zook. 
Gen. Coar. Frond tubular, membranaceous, of a green colour, and reti- 
culated structure. Fructification, granules, commonly in fours, con- 
tained in the cellules of the frond. Enrrromorrua (Lini),—from 
evrepov, an entrail, and popdn, form or appearance. 
Knreromorrua Cornucopia; gregarious, small; fronds stipitate, tubular 
at the base, suddenly dilated, widening upwards, plaited and laciniate 
at the margin.

Destr. Root 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 quadyate, something larger 
than in £. 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 con- 
tented to regard it, with continental authors, as a dwarf variety 
of #. intestinalis. Capt. Carmichael says, ‘‘ Without pushing 
the system of varieties to an extravagant length, this plant 
cannot be considered as a variety of L. cntestinalis ; the cha- 
racters of the definition mark it as abundantly distinct, and to 
these characters it is universally constant. I look upon it,
