32 ADDITIONS TO THE FLORA OF BKItWH K-ri'ON-T\VKKl>.

 House ; Mr Brown. 



STICTA FULIOINOSA. Langton Lee's Cleugh ; Mr Brown. 



CHROOLEPUS EBENEA. On shelving rocks in Edmonstone Dean, Ber- 

 wickshire ; Dr Johnston. 



SPHACELARIA CIRRHOSA. On the shore a little north of St Abb's Head ;

 dance ; Dr Johnston. Near Erableton ; Mr Erableton. 



ULVA DEFRACTA, Withering. Coldingham shore, after a storm ; Rev. Mr 

 Campbell. It is in some respects an interesting sea-weed, mostly 

 so in this ; that no one seems yet to have detected a specimen with 

 the slightest appearance of a root. Mr C.'s specimens were equally 

 imperfect. The plant was first discovered on the beach at Wey- 

 mouth, by Major Velley, and described by him in Withering's Ar- 

 rangement of British Plants. It was afterwards found by Mr Brodie 

 of Brodie, on the coast of Fife, who supplied the specimens figured 

 in English Botany ; and subsequently Messrs Borrer and Hooker 

 gathered it on the shores of the Orkney Islands ; so that, if a rare 

 species, it has at least an extensive geographical range. Dr Hooker 

 says it is very unlike any other ulva, " and has rather the appearance 

 of animal matter ;" but the opinion here hazarded has no foundation. 

 It is a true vegetable, as I am perfectly satisfied by a careful ex- 

 amination of it, possessing in fact the character of the genus Du- 

 montia of Greville, who, however, takes no notice of this species in 

 his Algse Britannicae : Dr Johnston. 



PALMELLA HYAUNA. In the Hirsell Lough, plentiful, swimming on 

 the surface in green gelatinous, globular, more or less lobulated 

 masses, from the size of a pea to that of a walnut ; Dr Johnston.

 tree in New-water-haugh wood ; Dr Johnston. About Eccles,
