CRYPTOGAMIA, ALGiE. Conferva. 
125 
Disjointed Fresh-water Conferva. First discovered in England by 
Mr. Dillwyn and Mr. Joseph Woods, jun. growing on decayed vegeta¬ 
bles in a pool on Hampstead Heath. Also found in Norfolk by Mr. 
Turner. E. Bot. and Dillwyn. E.)* 
(C. niv^ea. White, branched, slender, somewhat rigid: ultimate 
branches crowded, and often obscurely whorled: joints dark, 
about as broad as long. 
E. Bot. 2629. 
Dr. Willan has observed, that hepatic ga? is necessary to the growth of this 
plant. A deposition of an earthy kind is precipitated on the plant in 
consequence of its absorption of that gas, which had suspended or dis¬ 
solved the earthy substance; as Chane become incrusted with cal- 
cereous matter in hard waters. The incrustation conceals the joints. E. 
Bot. 
Snowy Conferva. Found by W. and J. Backhouse, Esqrs. of Dar¬ 
lington, growing on roots and dead leaves in the sulphur spring at 
Middleton. E.) 
(C. barba'ta. Pale crimson, repeatedly branched: joints swelling 
upwards, five times as long as broad ; the upper ones beset with 
opposite, branched, pale fibres: lateral shoots bearing tufts of simple 
filaments, enfolding many seeds imbedded in mucus. 
E. Bot. 1814. 
Fronds two or three inches high. 
Bearded Bed Conferva. Found on the beach at Brighthelmstone in 
July, by Mr. W. Borrer. E.) 
(C. L2ete-vFrens. Bright pale green, much branched, rather rigid: 
ultimate divisions pointing to one side; joints thrice as long as 
broad, with pellucid partitions. E. Bot. 
Billw. 48— E. Bot. 1854. 
Fronds floating horizontally, tufted. Mr. Dillwyn observes, that its light 
green colour and bushy mode of growth distinguish it. 
Light-green Bushy Conferva. Common on the shores of South Wales. 
Dillwyn. At Brighthelmstone. Mr. W. Borrer. E.) 
(C. pedicella'ta. Purplish, much branched, forked, capillary ; joints 
many times longer than broad, slightly swelling upwards; 
capsules obovate, on short stalks, solitary, from the forks of the 
branches. 
Dillw. 108— E. Bot. 1817. 
Fronds about three inches high, finer than the human hair, forming thick 
straight tufts, acutely forked at almost every joint. 
Fruit-stalked Purplish Conferva. Discovered by Mr. W. Borrer on 
Brighthelmstone beach in July. E. Bot. E.) 
* (This is one of several species of Confervas, and the only one retained in this work, 
which has latterly been considered by different learned naturalists as partaking more of 
the animal than the vegetable structure. Some of these minute microscopic objects 
are said to have been detected in motion. So intimately connected are the kingdoms 
of nature as scarcely to be determined even by the utmost aid of art, E.)
