lenticels. The presence of the water has so accelerated 
cell division that two or more lenticels have cohered and 
formed the bell-like sheath around the lateral root.

NOTES ON THE FLORA OF THE SCILLY ISLES. 
By W. W. Smiru, M.A. 
The first detailed account of the flora of the Scilly Isles 
is given by F. Townsend in the “ Journal of Botany,” vol. ii., 
1864, pp. 102-120, where 348 species are recorded. The 
next addition is given by M. A. Lawson, 24 species, 
“Journal of Botany,” 1870, vol. viii. pp. 357-358. In 
vol. xxxi, 1893, pp. 118-120, is a further list by A. 
Somerville giving 44 more, and in the same volume, pp. 
265-267, 64 more, culled by E. D. Marquand from the un- 
published papers of Ralfs on the Flora of West Cornwall. 
Ralfs visited the islands before Townsend, and the above 
64 represent those in his original list which were not 
recorded in the above three communications. 
The writer of this note visited the group in August 1906, 
and the twenty plants mentioned below are, I believe, new 
records. This makes a total for the islands of 500 species, 
of which 385 are Dicotyledons, 98 Monocotyledons, and 
17 Filices. 
Papaver somniferum, L.—Tresco. Occasional. 
Crambe maritima, L.—Old Town shore, St. Mary’s ; 
Tresco, St. Agnes. 
Armoracia rusticana, L.—Tresco. 
Brassica tenuifolia, DC—Tresco. Rare.
