��After making these additions and deductions, the whole Floni amounts to 753 out of the 1263 species given in Hooker's ' Students' Flora,' or to about 100 more according to Babington's ' Manual'; and if the 50 well- established naturalized species be added, the total will amount to about 800 or 900 species, according to the author followed, this being nearly three-fifths of the British flora.

Only five plants are in the British Isles peculiar to the Isle of Wight, viz. : —

Calamintha sylvatica. fMatthiola incana. '^

��Festuca ambigua. Arum italicum.

��Chara alopecuroides.

��The Isle of Wight shares Gladiolus iUyrlcns with Hampshire, and Pitl- monaria angnstifolia with Hants and Dorset, while such plants as Cyperus longus, Melampyrum arvense, and Orobanche ccendea, are among the rarest of English plants.

No enumefrttion >f a flora can be complete without considering the proportion of naturalized plants, and the conditions under which they oc- cur ; and I hope to return to this subject on a future occasion.

Ekrata. — Ou page 73, "Annual Report for 1859" should be "for 1858." It was published in 1859.

The volumes of ' Piiytologist' in which Dr. Bromfield published his Catalogue date from 1848 (not from 1847) to 1851.


Stler trilobum, Scop., IN England. — In the beginning of June, 1867, I found, upon rough chalky rising ground near Cherry Hinton, Cambridgeshire, growing amongst Rubiis, Viburnum Lantana, and other plants characteristic of a calcareous soil, an Umbelliferous plant which I could not determine, but imagined to be a variety of Smyrnium Olusatrum. Ou the 25th of May, 1871, I again visited the spot (being the first op- portunity I had had' since 186?), and found the plant still growing there. i took specimens to the British Museum, where it was determined to be Siler trilobum, Scop. { = S. (ajuiU'yio'fulium, Giertn.). The locality is a limited one, and more so now than formerly, owing to the increase of cultivation (Clover principally) on the bushy, chalky ground below. It is singular that, in the immediate neighbourhood, grow two very rare British Umbelliferce, — AUmmanta Libanotis and Buuium Bulhocadanum ; but, whereas the latter of these grows exclusively, so far as I could see, in the semi-cultivated ground near, amidst Sainfoin and Clover, the Siler affects the uncultivated chalk. It seems strange that such a large plant should have, until now, escaped detection ; but I have Professor Babing- ton's authority for stating that it has always been hitherto considered to be Smyrnium Olusntrum, — to which, when young, the leaves bear a strong resemblance, — and is entered as that species in the ' Flora of Cambridge- shire,' p. lOl'. Jacquiu's description of its habitat in Austria, " in asperis et calcareis montibus," agrees admirably with the Cherry Hinton locality. — J. Cosmo Melvill.
