_ « A very low, compact, little shrub, rarely exceeding a 
foot in height. The prickles are large, stout, and nearly 
straight. Leaflets ovate, acute, flat, very finely toothed. 
Petals small, pale-blush, pointed: germens 7-8. Otherwise 
with the characters of Rosa semperflorens, from which I 
nevertheless have no hesitation in separating it. The dif- 
ference in number of germens in this division appears con- 
stant, and therefore important. Mr. Sweet introduced it 
from the Mauritius (Isle of France), some years ago, and 
it may be the Rosa pusilla of the Catalogue of the Botanic 
Garden there. China is probably its native country, as it 
approaches so very nearly to Rosa semperflorens.” Lind. 
mon. l.c.  ~ ; 
The species was named by Mr. Sweet in the “ Hortus — 
Suburbanus Londinensis” in compliment to Miss Lawrance, 
the fair artist, by whom “ The Collection of Roses from 
Nature, with 90 plates” was executed. 
_ The plant's being specifically distinct from Rosa semper- 
florens is much doubted among the cultivators of this genus. 
We ourselves have no opinion upon the subject. 
The drawing was made at the nursery of Messrs. Colvill, 
in the King’s Road, Chelsea.
