ALGiE INARTICULATE. 297 



On rocks and on the larger Algce on the coast of Dorset (Goodenough 

 •and Woodward). Isle of Wight, Rev. G. R. Leathes. Devon {Mrs. 

 Griffiths), and Cornwall (E. #o/.). 0. Summer.— 6 — 8 inches high. 

 Readily distinguished by its very slender uniform ultimate ramuli or 

 pinnules. — I possess most beautiful specimens from Mrs. Griffiths, 

 gathered at Elberrey Cove, in fructification. 



33. Chylocladia. Grev. MSS. Chylocladia. 



Frond cylindrical, filiform (often constricted as if jointed), 

 between gelatinous and cartilaginous, of a pinky-red colour. 

 Fructification of two kinds : — 1. spha?rical, ovate or conical cap- 

 sules,\\\t\\ wedge-shaped or angular seeds : — 2. imbedded, ter- 

 nate granides. Grev. Alg. Brit, (under Gastridium) p. 114. 

 t. 14. — Name K-Sho, juice, and/CA«6o;, a branch, from the succulent 

 nature of the ramuli.— The name Gastridium having been pre- 

 viously given to a Genus of Grasses, it has been necessary to 

 change it. 



* Frond without constrictions. 



1. C. clavellosa, (clavellated Chylocladia) ; frond subgelatinous 

 filiform cylindrical much and irregularly branched, brandies and 

 ramuli mostly alternate and distichous, ultimate ones more or

In the sea, on rocks, or parasitic on the larger Algae, on almost all our 



coasts. 0. Su er — The ramuli are usually simple; but, as Dr. Ore- 



vilie remarks', sometimes elongated to half an inch or more, constricted 

 ;; or 1 times, with a few minute branchlets at the constrictions, a-> in the 

 following species; from which it is in other respects considerably 

 different.
