CRYPTO GAMI A. AL GM. Conferva, 
C. tubulo'sa. Thread-shaped, jointed; joints alternately compressed. 
Linn. Very much branched: joints oval. Huds. 
Dill. 6. 39. 
From two to four inches long, irregularly divided and sub-divided into 
branches, yellowish green. Branches knotted or jointed, hollow. Dill. 34. 
(Oval-jointed Conferva. E.) C.tubnlosa. Huds. 600. Ulva confervoides. 
Linn. In Gmelin Syst. Veg. it is entered, by oversight, both as a Con¬ 
ferva and as an Ulva. 
Rocks and stones in the sea; and on Fuci. A. Summer. 
(C. confervic'ola. Glaucous green: filaments unbranched, shortish, 
clustered, taper-pointed : joints four times as broad as long. 
E. Bot. 2576. 
Forming tufts of filaments one-eighth of an inch long. 
Pointed Parasitic Conferva. Frequent in the sea on other marine 
plants. E. Bot. E.) 
C. seta'cea. Threads forked: branches very long, bristle-shaped; 
joints cylindrical. Huds. 599« 
(.Dillw . 82— E. Bot. 1689. E.)— Dill. 6. 37. 
Sometimes forked, sometimes irregularly divided, divisions more or less 
frequent, but I have never observed it entire. Colour reddish purple, or 
greenish red. Dill. (A beautiful species, three to six inches long. E.) 
The figure of Dillenius is by no means characteristic. This is evidently 
distinct from C. corallina, the joints are much more slender, and not thick 
at the ends. It differs also from that species in producing short lateral 
thorn-like substances. Fructifications in globular clusters on short lateral 
pedicles; rarely found. It may readily be known by the intolerable 
odour which it imparts when recent. Major Velley. (Its beautiful crimson 
colour is owing to a liquid in the cavity of the joints, which may be 
pushed to either end of the joint but not beyond the septum. On cutting 
through a joint, and pressing out the liquor, the plant remains colourless, 
and the liquor under the microscope appears to be a mucilage containing 
a great number of very minute seeds. 
Crimson Setaceous Conferva. E.) Stones and rocks in the sea. (Yarmouth. 
Mr. Turner. Anglesea. Rev. H. Davies. E. Bot. E.) A. May—Oct. 
C. elonga/ta. Branches forked, long, bristle-shaped: joints very 
short. Huds. Ed. 1. 484. Ed. 2. 599- 
(Dillw. 33— E. Bot. 2429. E.) 
Threads nine inches to a foot long, of the thickness of fine packthread, 
smooth, brownish purple, branched at the base. Branches very long. 
Finds, n. 27. (The largest British Conferva. Dillw. E.) 
Lobster-horn Conferva. Hutchinsia elongata. Agard. Hook. C. elon- 
gata of Gmel. Syst. Veg. is Hudson’s C. rubra. Fucus diffusus of Hudson 
is now declared to be no other than this plant. That author appears 
to have been deceived by its substance being of a somewhat firmer 
texture than the Confervse usually are. On oysters. E.) Stones and 
rocks in the sea on the coast of Devon, Cornwall, Sussex, and Isle of 
Man, (Portland Island, &c. E.) A. April—Oct. 
C. ciLiA f TA. Threads forked, the points approaching like forceps: 
joints fringed. Huds. 599-
