 Rocks at Hartlepool; Mr. Backhoufc. 



Mifs Hutchins firft difcovered this fpecies of Conferva in the neighbour- 

 hood of Bantry, and the prefent defcription is made from a drawing and 

 fpecimens which fhe fent to Mr. Turner. The filaments grow to the 

 length of about half an inch, and according to Mifs Hutchin's obfervations 

 throw out fibrous roots towards their bafe. The color is of a brownifh 

 olive : the branches, which are erect and difpofed without order, are uni- 

 formly fimple with obtufe apices. The joints are about equal to half of 

 the diameter. The fructification is in capfules which are moftly feffile, 

 numerous, and difpofed on the filaments without order. The fubftance is 

 rather ftiffand not in the leaft gelatinous, fo that in drying it adheres to 

 neither glafs nor paper. The drawing at plate C was made by Mifs 

 Hutchins from the recent plant, and reprefents it both of its natural fize 

 and when magnified 3, to which Mr. Hooker, from a dried fpecimen, has 

 added a piece of a filament magnified I.

 On Wet Rocks in a Cave near Dunrea, Ireland. Mr. Robert Brown. 

 This plant I introduce entirely on the authority of Mr. Brown, who con- 

 fiders it as a diftin£r. fpecies, and to whofe judgment in all matters relating 

 to Botany, the greateft deference is due. He alone has obferved it, and I 

 have a plcafure in publifiiing it with his name. The following defcription 

 was made by Mr. Brown from recent fpecimens. " In ccefpitibus denfis 

 nunc convexis nunc planiufculis latioribufque. Filamenta (quail fafcicu- 

 lata) erecla, ramofiflima, 1-! ad 2 lineas longa, craffiufcula, rigidula; ramis 

 fub-fecundis, dichotomi ; articulis multoties longioribus quam latis, pluri- 

 bus apicem verfus fenfim incraffatis, paucis cylindricis. Fru£iificatio nulla 

 vif.i." The ramifications and joints are fo nearly fimilar to thofe of C.
