84 MARINE ALGiE NEW TO CORNWALL AND DEVON. 



only specimens which I was able to submit to Prof. Gray are those 

 above named. The Cambridgeshire (Wicken Fen) plant, described 

 by Prof. Babington (Jom-n. Bot., v., 367-9 (1867) ) as A. saUgnus, 

 Willd., is there identified by him with the Tay-side species above 

 referred to. To an unpractised eye, the specimens placed under 

 A. i)(iniculatus by Prof. Gray are somewhat dissimilar from each 

 other; but his recent thorough study of this complicated and 

 puzzling genus entitles his opinion to be accepted as final. 



With reference to the Eichmond Thames-side paniculatus, I 

 first noticed it in that locality — which is just opposite the Eailshead 

 Ferry to Isleworth — sixteen or seventeen years since, when it was 

 much more abundant than it is at present. In Loudon's 



* Magazine of Natural History ' for 1828 (i., 83) is a note, signed 

 'E. K.,' stating that Aster Tripolium had been gathered by the 

 writer ''in 1824 on the banks of the Thames, a little above high- 

 water mark, on the way between Eichmond and Kew." I think it 

 likely that A. paniculatus may have been the plant here intended; 

 as I doubt whether A. Tripolium would extend so far up the river. 

 This record is not included in the ' Flora of Surrey,' in which, 

 indeed, there is no mention of A. Tripolium; but I may perhaps be 

 allowed to add that I have a very distinct recollection of having 

 gathered that plant by the Thames at Battersea, at a date when 



* Battersea Fields ' was still in existence, and before the present 

 Park was formed. 



MAEINE ALG^ NEW TO COENWALL AND DEVON. 



By E. V. Tellam. 



The following additions to the list of Algae for Devon and 

 Cornwall were collected by me during 1880 : — 



Stilophora Jolisii, Thuret. — On stones at the bottom of a salt 

 water mill-pond at the west side of Looe, where the tide flows 

 into the pond. 



Ectocarpus Crouani, Thuret. — Growing on Zostera marina at half- 

 tide at Eedding Point, Mount Edgecumbe ; and at Trevone Bay, 

 near Padstow, on Chorda Filum.. 



E. ramellosus, Kuetz. — On sloping clay-slate rocks, shaded from 

 the sun, in a small creek at Harbour Cove, Padstow. 



Melohesia Leiiormandi, Arescli. — On trap rocks at half-tide, at 

 Permisson Bay, Padstow, and at Sidmouth. 



M. CorallincB, Crouan. — On Corallina ojficinalis, Trevone Bay, 

 Padstow, and St. Minver : this does not ai)pear to be uncommon 

 on the Cornish coast. 



Grateloupia dichotoma, J. Ag. — On the perpendicular sides of 

 rocks in pools shaded from the sun by higher rocks or clifls. First 

 observed at Trevone Bay, Padstow, by E. M. Holmes. I have 

 found it at St. Minver, and at the Gull Eocks, Plymouth, with 

 fruit.
