FLORA OF FORFARSHIRE. 
of Perth, as between Meigle and Alyth, and in the Carse of 
Gowrie. 
A curious freak of nature, in a flower of the sweet-briar, 
was observed at Ninewells, in June 1829. In this instance 
the corolla was exterior to the calyx, and many of the sta- 
mens were petalloid, some of the filaments being surmounted 
by little rose-coloured petals, and others expanded into the 
form of petals, having their margins bordered with anthers. 
R. canina , L. Common Dog-Rose. H. 106, B. 100. — 
F. June, July. S. 
The most common species throughout the county, but very 
variable, and the varieties so difficult to define, that one 
would almost require to devote his attention to them exclu- 
sively, in the living state, for several seasons, and even then 
he might not be able to satisfy himself of their identity as 
distinct species, varieties, or forms, or whatever else he might 
choose to call them. The Roses are perhaps the most beau- 
tiful plants that exist in any clime, and are always pleasant 
to the eye that loves beauty, but to the botanist they often 
offer as many thorns as flowers.
