 This is Dearly related to E. ramulosa, bul la of a i 

 softer substance, usually more slender in its tube, and more 

 repeatedly branched, so thai Its tufts are more bushi 

 feathery. It frequently lies prostrate, forming a widely- 

 spreading fleecy covering either to rocks or to mud, but this 

 character is not very constant. To JS.erecta it is also 

 closely allied, but is of less plumy habit than that Bp< 



with less difference in diameter between the main - 



and branches and their lesser divisions, and the ramuli are 

 shorter and more Bquarrose.

 Hah. Rocks and -tones, between tide-marks. Annual. Spring. 

 A fsowmonform of EnU romorpha, but scarcely more than 

 a form. K. ramulosa and K. <-I<ithr<t(u have so much in 

 common will) E. erecta and others of the genus, that it is 

 doubtful whether all are m>t merely varieties of one protean 

 species. The present variety is distinguished by its Bquar- 

 rose habit, full-green colour, and rather harsh feel. When 

 young and untangled, it is not unsightly ; hut in 

 often forms an inextricable fleecy mass, spreading widely 

 over the surface of the ground, ami forming a comfortable 

 cover for a variety of small crustacea and shell-fish.
