" The main stems originate from tubular creeping roots, which in- 

 vest marine jijants in shoal water : these stems are often jointed at un- 

 equal distances, and give off a number of short branches, which ori- 

 ginate in pairs from its opposite sides, frequently just above a visible 

 joint ; these branches support the vesicles, which are scattered over 

 their surface in an irregular manner, and do not differ except in size 

 and number of tentacula, from those of V. imbricata : the tentacula 

 being 8 in number." Thompson — " Height seldom above two 

 inches; several stems usually arise from the same base, fiUform, 

 jointed, waved, and support the branches and cells bifariously ; bran- 

 ches opposite, nearly perpendicular to the stem, with a joint imme- 

 diately above their insertion : cells oval, sessile, upwards of ten times 

 the breadth of the stem, in pairs, at remote distances, projecting, and 

 are probably ultimately converted into branches : sometimes they oc- 

 cur in pairs or crowds in the axillae of the branches ; polypi extend 

 considerably beyond the margin, tentacula with hairs, which, by their 

 motions, cause the water to ascend in a current on one side, and de- 

 scend on the other, acting, probably, as aerating organs." Fleming.
