ADDITIONS TO THE MARINE FLORA OF 
THE CHANNEL ISLANDS. 
By Lilian Lyle, F.L.S. 
These additions have been gathered from various sources. I am 
indebted to Dr. Rendle, Keeper of the Department of Botany, 
British Museum, for the opportunity of looking through two collections 
of algae recently acquired by the Department, wherein a number of 
species and varieties not yet recorded for either Jersey or Alderney 
were noted. Mr. Gepp, of the same Department, kindly showed me 
a collection from Guernsey made by Lady Mansell in 1840, which 
included specimens of great interest; none of these had been deter¬ 
mined, but they had been carefully mounted and preserved. Lastly, 
a recent visit to Guernsey enabled me to explore again my old hunting- 
grounds, and I was fortunate in finding several algae new to the 
locality and one new to science. 
An account of the marine flora of Jersey was published in LOOS 
by Dr. A r an Heurck entitled the “ Prodrome de la Flore des Algues 
Marines des lies Anglo-Normandes et les Cotes Nord-Ouest de la 
France.” The lists of seaweeds gathered by him and other collectors 
are very extensive and apparently exhaustive, but as a result of my 
examination of the above-mentioned collections I have been able to 
add sixty species and varieties for Jersey and AldernejL The new 
records are as follows :— 
Jersey. 
Jdnteromorpha paradoxa Kiitz. forma typica Batters; also var. 
tenuissima (Kiitz.) Batt. ( = _£'. llopkirkii McCalla). 
Cladophora arcta Kiitz. var. radians Batt. 
DictyosipJion liispidus Kjellm. Dr. Van Heurck enters this as 
“forma subhispida ” of D. foeniculaceus ; Kjellman had figured and 
described it as a subspecies of D. foeniculaceus in Spetsbergens 
TJiallophyter , ii. 187(3, t. 2. The plant differs markedly in form 
from I), foeniculaceus , the frond being clothed with short branches 
“ subulate or linear about a line in length.” Batters has therefore 
rightly made of I), hispidus a separate species. 
Punctaria tenuissima Grev. 
Asperococcus fisiulosus Hooker var. vermicularis (Griff.) Harv. 
Chorda fomentosa Lyngb. 
Chantransia Lorrain-Smithies mihi (see Journ. Bot. lviii. 1920 r 
Suppl. 2. p. 13). 
Gelidium latifolium Born. var. laciniata Batt., very rare. There 
is only one other record for this plant in the British Isles—Tor
