The more common appearance of the Rose here figured, is a compact, much-branched bush, with pale red flowers,
growing in threes, with bristly scarlet fruit, and bright green but not shining leaves; these last being powerfully
and gratefully fragrant. All these characters are, however, liable to considerable variation, and have been the
foundation of a multitude of supposed species.
My variety, /3. Rosa micrantha, was first proposed as a species by Sir J. E. Smith, in English Botany; and has
been more recently adopted by Mr. Woods, who attempted to discriminate it by its long fruit, and the equal size
of the prickles. But these appearances are very inconstant, and may not unfrequently be observed in the indisputable
Rosa rubiginosa. It is common in the south of England with very small flowers; but Mr. Lyell, who has
had constant opportunities of watching it, is unable to distinguish it essentially from the common Szoeetbriar. The
