Petasites albus, Gartn. 
During a recent examination, at the British Museum, of a herbarium col- 
lected by me at Aberdeen, in boyhood and early youth, a specimen labelled 
" Petasites vulgaris, found near Woodhill, 15th April, 1841," has proved not 
to be that species, but the partially naturalized Petasites albus, Gartn., figured by 
Mr. J. T. Boswell Syme, F.L.8., in his edition of the c English Botany,' vol. v. 
phte 782. Having written on the subject to my friend Professor Dickie, he 
was kind enough to visit Woodhill, which he states to be a small property 
about two miles north-west from Aberdeen. On examination, he found there, 
opposite to a gate, an irregular heap of rubbish, evidently cast out at vanou9 
times from the garden ; and, growing on it, Petasites albus, JEg op odium, etc. 
The plant, therefore, is not indigenous in that locality : but yet.Woodhill 
must be added to the two stations near Aberdeen, mentioned by Mr. Syme as 
places where the Petasites alius is becoming partially naturalized ; and the 
interest attaching to the Woodhill habitat is the evidence now afforded that, 
though the plant is limited to a very circumscribed area, it has still apparently 
succeeded in maintaining itself there for upwards of a quarter of a century.

Description de la Flore fossile du Premier Etage da Terrain Cretace du 
Hainaut. Par Eugene Coemans. (Prom the Memoires de 1'Aca- 
demie Royale de Belgique, vol. xxxvi.) 
M. Coemans has in this memoir described a very curious flora, the 
species of which have as yet been found only in the one locality. I* ie 
precise age of the deposit in which they occur is uncertain. It rest* 
upon carboniferous rocks. And although MM. Cornet and Briart, 
who have examined the stratigraphical structure of the district, state 
that, like most other geologists who have studied the country, tbej
