CRYPTOGAMIA. ALGJE. Confeeva.

(C. nummuloi'des. Simple, slender, brittle, palish brown: joints 
rather broader than long, red in the centre, combined in pairs. 
E. Bot. 2287. 
Filaments short, tortuous, cylindrical, brittle ; of a dirty white, except that 
in the centre of each joint is a round assemblage of seeds of a yellowish, 
brownish, or red colour. 
Money-wort Conferva. Gathered by Mr. Borrer in Shoreham Harbour 
adhering to other Conferva. In the river Lea. Mr. Dillwyn. E. Bot. E.) 
(C. vagina'ta. Glaucous green, branched, cylindrical, obscurely 
jointed; joints as broad as long; several branches embraced in 
one sheathing membrane. 
Dillw. 90— E. Bot. 1995. 
The fronds grow close to the ground, or garden-pot, crossing each other, 
forming a sort of irregular net-work, slippery and moist. Here and there 
are found lateral balls containing coiled filaments. E. Bot. When cut or 
pressed, it divides into smaller plants of the same kind, these interior 
plants being thrust out at the end or burster) sides gives it a branched 
appearance ; grows very quickly. Gray. 
Sheathed Conferva. This vegetable, so minute and of so curious struc¬ 
ture, appears to be not uncommon during the moist mbnths of winter on 
the earth of garden-pots, foot-paths, &c. E.) 
(C. atro-purpu'rea. Deep purple; filaments simple, at length 
swelling unequally ; joints about as long as broad, with a double 
transverse'row of seeds in each. 
Dillw, 103— E. Bot. 2085. 
The structure of this minute plant is only observable through a microscope. 
In its natural size it has the appearance of purple hairs an inch long; 
when magnified the root is found to consist of a tuft of fibres: each frond 
is quite simple, finer than human hair. 
Dark-purple Simple Conferva. E. Bot. E.) 
(C. cur'ta. Pale brown: filaments simple, cespitose, rigid, nearly 
upright, tapering at the base ; joints slightly tumid, as broad as 
long. 
Dillw. 76—E. Bot. 2084. 
The short simple fronds form dense rigid tufts, about a line high ; slightly 
beaded from the swelling of the joints. E. Bot. 
Short Conferva. On Fuci in the sea near Plymouth. Miss Hill. Ditto, 
Swansea. Dillwyn. E.) 
(C. vivipIara. Green, alternately branched: joints five times as long 
as broad, swelling upwards; each bearing a lateral, very long, 
slender, simple branch; bulbous at its base ; capsules lateral, 
sessile. 
Dillw, 59—E. Bot. 2086. 
The fronds compose dense continued masses on various aquatic plants, from 
two to six lines high. Each stem is alternately branched, zigzag. 
From the top of each joint springs a very long and extremely fine, simple, 
hair-like branch, not one tenth so thick as the main stem. E. Bot.
