ENTEROMORPHA RAMULOSA, Zook. 
Grn. Cuar. Frond tubular, membranaceous, of a green colour, and reti- 
culated structure. Fructification ; granules, commonly in fours, 
contained in the cellules of the frond. Hnreromorpna (Link),— 
from évrepoy, an entrail, and poppy, form or appearance. 
EnteromorpHa ramulosa ; frond subcompressed, highly reticulated, irre- 
gularly divided; the main divisions long, densely set with lateral 
branches; branches curved, curled or twisted, everywhere clothed 
with short, spine-like ramuli.

Descr. Fronds from six inches to one or two feet in length, densely tufted, and 
often woven together into an inextricable mat, irregularly branched. Main 
stems frequently undivided or but slightly divided, furnished throughout 
with densely set, short, horizontal branches of very unequal length, some of 
them being not half an inch and others two or three inches long. These 
branches bear an abundance of short, spine-like, simple or slightly branched, 
scattered, setaceous or capillary ramuli, very much more slender than the 
part from which they spring. The stem and branches all taper to a fine 
point. The colour’is an intense grass-green, of much brilliancy, and well 
preserved in drying. The substance membranaceous, rather harsh to the 
touch from the abundance of short spreading ramuli that cover the branches. 
In drying the frond adheres, but not very closely, to paper.

A common form of Hnteromorpha, but scarcely more than a 
form. Under Plate XLIII. of our first volume I have stated 
that I regard #. ramulosa as merely one of the varicties of 
f,. clathrata, and that both the plants so called have so much in 
common with Z. erecta and others of the genus, that it is doubt- 
ful whether all are not merely varieties of one Protean species. 
To this opinion I still adhere. Nevertheless, as the extreme
