CONFERVA CARNEA.

On Conferva in the River near Loughor, Glamorganfhire. IF. JF. Young. 



IN September, 1805, Mr. Young brought me the prefent delicate fpecies from 

 the rocks in the Loughor river, where he gathered it, near to its confluence 

 with the fea. It grows on other conferva:, in loofe tufts, moftly from a quarter 

 to half an inch in length, and of a pale red or flefh color. The filaments are 

 Ample, and taper in fome degree both towards their root and apex, but terminate 

 rather bluntly. The diflepiments are of a dark color, and at regular diftances 

 from each other ; the length of the joints in fome filaments is about equal to 

 twice their diameter; and in others the length and diameter are nearly equal. 

 They are rounded off at both extremities, and moft fwollen towards the upper, 

 fo that when examined under the higher powers of the microfcope they bear 

 fome refemblance to thofe of Corallina officinalis. Among a number of young 

 and apparently vigorous fpecimens which Mr. Young examined, while they were 

 quite frelh, he could not find one joint through which the juices were entirely 

 difFufed, and of which the greater part was not colorlefs, fo as to induce him to 

 believe that the red globules, of which one appears in each joint, are not the 

 efFe£t of a collapfion of the juices from age or expofure to air, but natural to 

 the plant in its moft perfect ftate; in fome fpecimens however which I examined 

 when nearly frefh, I found that in the older filaments the red fpot was confider- 

 ably fmaller in proportion to the fize of the joint than in the younger ones, and 

 I therefore prefume that they proceed entirely from a collapfion of the juices, 

 which probably takes place in this more quickly than in moft other fpecies. L 

 have not been able to difcover the fructification.
