180 SYNOPSIS OF BRTTISTI SEAWEEDS. 



For the present we have placed Ochloehate with the 

 ChatophoretB, from which family, however, it will even- 

 tually have to be removed, Bince it differs from Chceiophora 



(that is. the typical species C. elegans, A_, r .) and Drapar- 



naldia in some important particulars, as described in k Phy- 

 cologia Britannica,' pi. 226. 



Order 16. TJLVACEM. 

 XCV. ENTEROMORPHA. 



330. Cormicopise (The cornucopia* Enter omorpha) ; gregarious, 

 small ; fronds stipitate, tubular at the base, suddenly dilated, 

 widening upwards, plaited and laciniate at the margin, 

 HooTc. Br. Fl. v. 2. p. 313. (Atlas, PL LXXII. Fig. 339.) 



Scytosiphon intestinalis, var., Lyngh. Solenia intestinalis, var., 



Ag. L x lva intestinalis, var., Ag. 

 Hah. On Corallines, etc., in rocky pools left by the tide. Annual. 



Spring and summer. 

 Had not this plant been admitted to the rank of a species 

 by the late Captain 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. 



331. intestinalis (The intestinal Enteromorpha) ; fronds per- 

 fectly simple, elongated, becoming inflated, obtuse, tapering 

 extremelv to the base, Link, Hor. Phys. Ber. p. 5. (Atlas, 

 PL LXX. Fig. 329.) 



Solenia intestinalis, Ag. S. Bertolini, Ag. Scytosiphon intes- 

 tinalis, Lyngh. Eistularia intestinalis, Grev. Ilea intesti- 

 nalis, Gaill. Tetraspora intestinalis, Lesv. L T lva intesti- 

 nalis, Linn. Conferva intestinalis, Both. 

 Hah. Attached to various substances in the sea, between tide- 

 marks ; also in brackish and fresh-water ditches near the 

 coast. Often floating. Annual. Summer. 

 A very common shore-plant in all parts of the world, 

 extending from the limits of vegetation in the northern 

 hemisphere through all intervening latitudes to a similar 

 point in the south ; and inhabiting not merely the sea. but 

 brackish, or even fresh- water ditches in the neighbourhood 

 of the coast. It varies greatly in size, and in the degree 

 of inflation, but in no other characters. Broad varieties of 

 E. comprcssa strongly resemble some of its states, but these 

 are always branched, though often in a very slight degree ; 

 whereas E. intestinalis is invariably simple. E. intend-
