136 HISTORY OF BRITISH ZOOPHYTES. 
bare of branches. It is very beautiful in its young state, 
when it is only two or three inches in height. It is then 
found in clusters of twenty or thirty close together; but 
when there are only three or so in the cluster, it is pecu- 
harly handsome, resembling a silvery Prince of Wales’s fea- 
ther. I had the pleasure of finding it in this juvenile state 
several times betwixt Leith and Portobello. I have had 
many fine specimens of it found in the Mersey by Mr. Tu- 
dor, and many also found by Miss M‘Leish and the Misses 
Steel, in the Dee, Cheshire. As it is rarely found on the 
Ayrshire coast, I was happy to get a good supply from 
Miss Griffiths and Miss Cutler when I had the great plea- 
sure of visiting them in April, 1851; and, being greedy of 
such beauties, I added to my stores, when about the same 
time I enjoyed the happiness of an excursion with Mrs. and 
Misses Gulson to the Warren, opposite to Exmouth. The 
Warren is, with the exception of Guernsey and Jersey, the 
only habitat in Britain for the beautiful little crocus-like 
plant Zrichonema columne, and a gladder note of exultation 
was raised by us all on its being discovered by Miss Gulson, 
because there were fears that it had been eradicated, as seve- 
ral botanists had been searching for it im vain.
