I HAVE been favored with a fpecimen of this plant gathered by the Rev. 

 Hugh Davies, and which was marked by Hudfon " C. albida." The fpecimen 

 in the Dillenian Herbarium according with Hudfon's reference is however very 

 different, and agrees better with both the name and defcription of that fpecies. 



Mr. Hooker favored me with the prefent drawing from a fpecimen which lie 

 gathered during his late tour through Scotland, and I have a pleafure in em- 

 bracing the opportunity it affords me of thus acknowledging the great a (lift a nee 

 which I have received from him, by diftinguifhing it with his name. 



C. Hooheri grows to the length of two or three inches, and whilft recent has a 

 remarkably gelatinous appearance. The color is a pale reddifh brown. The 

 principal ftems are entirely deftitute of difTepiments, and are of an unequal 

 thicknefs, fo that if examined feparately they might be miftaken for an Ulva : 

 they are however befet with pinnated, flexuofe, jointed ramuli, and which are 

 remarkably (lender in proportion to the thicknefs of the (lem : the pinnuhe are 

 alternate. The length of the joints is about half greater than the diameter. 

 The capfules are nearly globular and of the fame nature with those of C. rofea. 

 It is in fiae and mode of growth nearly allied to C. arbuaila, but differs in its 

 color, in being branched throughout its whole length, in having pinnated 

 inftead cf multifid ramuli, and in the (hape and difpofition of its capfules.
