Plants much calcified, varying in length to about 9 cm. Root-mass bulbous to elongate. 

 Stipes simple, 1 — 2.5 cm. long, varying to 0.5 cm. thick, corticated, cortex finely spongiose 

 or velutinous, subterete below, flatly expanded and cuneate above and (in structure) passing 

 gradually into the flabellum, the base of which is corticated. 



Frond narrowly or widely flabelliform to subreniform, up to 7 cm. long and 1 1 cm. 

 wide, pluriseriate, plane, sometimes divided above into 2 — 3 wide overlapping lobes, often zoned, 

 green to ashy-white, surface minutely and longitudinally filamentoso-striate above, velutinous or 

 spongiose towards and at base ; margin subentire to eroso-lobate. 



Filaments of frond 25 — 50 a (rarely 70 a) in diameter, here and there larger, calcified, 

 radiating from the stipes to the margin, repeatedly dichotomous, as a rule evenly constricted 

 above the dichotomies, flexuose, pluriseriate, somewhat felted and conglutinated together and 

 stiffened by calcareous deposit. Filaments at base of frond, for a short distance above the 

 transition from stipes, concealed under a loose covering of fibulae or lateral branchlets, shorter 

 and simpler than those of the stipes. 



Filaments of stipes bearing lateral branchlets, dichotomously divided, and terminated by 

 apices which vary from dactyline to abbreviated and obtuse, and are approximated together 

 so as to form an external cortex, hardened by a calcareous deposit. [Figs. 44 — 46]. 



The type of this species is, as stated above, the Corallina conglutinata of Ellis and 

 Solander ; and though unfortunately the original plant has been lost, it is quite easy to grasp 

 the identity of this species. The main characteristic, which is implied in the name, to wit, the 

 "branches dichotomous and glued together, but not covered" is further explained in the fol- 

 lowing note by the authors (loc. cit. p. 125): "We can plainly distinguish all the dichotomous 

 "branches of this Coralline on its surface, which are each of them separately covered with a 

 "thin calcareous substance full of pores ; these, by growing so close to one another, become 

 "glued or united together by their covering. This was found on the coast of the Bahama 

 "islands. It is of a seagreen color, and one inch and an half high". This makes their species 

 tolerably unmistakeable and supplements what is poorly rendered in their fig. 7 on tab. 25.
