path between the Mill and EfFord Manor-house ; at Shalaford,

Rosa micrantha is one of our commonest roses, its abundance being 



quite a noticeable feature in the local flora. The petals vary in colour 



from very light pink to rose, but seem never to have the full deep rose 



of those of ruhiginosa. The odour of the plant is generally stated to 



be ' faint ; ' but it can only be said to be so in comparison with that of 



the true ' sweetbriar.' The fruit varies from ovate or urceolate to globose, 



and sometimes is sparingly setose, though usually naked, except close to 



the peduncle. I am not aware that the naked peduncled variety has 



been found anywhere else in Britain, though Dr. Christ has recorded it 



from Vallee de Clanzo, near Santa Anna, on the Maritime Alps. Our 



plant has the sepals eglandular at the back. It does not seem to be 



dependent either on soil or situation for its peculiarities ; for it and the 



type often grow in the same hedge-row, and it occurs on soils differently 



constituted. A luxuriant form of it is the var. Briggsii of Baker's 



Monograph. The late Rev. A. Bloxam sowed seeds I sent him, and 



found it come true. M. Deseglise places it under R. tomenteUa, Leman, 



an arrangement that I cannot follow. In the neighbourhood of Plymouth 



R. micrantha, not R. ruhiginosa, sometimes constitutes the 'sw^eetbriar' 



of cottage gardens.
