subject of these notes is oreditad with being subdice , but as 
vt n 
of specimens from various localities within the last two or three 
years—the species is distinctly diwcious functionally, if not abso- 
lutely so, from a purely structural standpoint. “A good m many 
British botanists seem totally unacquainted with the fotnale plant, 
and the distribution of the two sexes in Britain never seems to 
have been worked out. With a view of calling the attention of 
workers in various parts of the country to these points of interest, 
the following notes are pee written. The male plant is un- 
doubtedly by far the most common in Britain, and, judging from 
same remark holds good with regard to the Continent. The flower- 
heads are more shortly stalked, and are much larger than those of 
the female; the silky white pappus is aig and much less 
abundant, and the style-arms never separate, but form a thick 
clavate mass. In the female, on the other hast the flower-heads 
are considerably smaller, and a baigpens as a rale, much more 
a 
; the nd

connate, as in the ordinary male plant. The ie of the 
male plant i is as follows :—Petasites vulgaris Desf., P. riparia Jord., 
P. Reuteriana Jord., sea Petasites L. That of the female— 
Lussilago hybrida Gy. T. Sebethia Ten., Petasites “ B. hybrida 
Hook., P. pratensis Jord I ate not seen specimens of P. con- 
similis Jori., P. macroph yllus Schur., and P, satarnidia es if 
am not certain _to which of Pcoxes to refer 
‘Specimen from Egham, Surrey, and andes sie Munden Bog, 
Shire both sexes grow together in great abundance, as also in 
Northumberland and Laneashire. I ‘have seen specimens of the 
ey plant also from near Glasgow and Edinburgh ; an Dr. J. 
deen. The Orkney plants, kindly sent me by De. H. Halero 
ohnston, were all males. From the Continent I till we speci- 
mens from two or three localities in France, Switzerland, and
