110 ROSA LAWRANCEANA. 
60. ROSA Lawranceana. - 
R. nana, foliolis ovatis acutis arguté serratis, petalis 
~ acuminatis, ovariis 7-8. 
R. semperflorens minima Sims. bot. mag. n. 1762. 
R. pusilla Mauritius cat. p. 15: 
R. Lawranceana Sweet! hort. sub. lond. 
Hab. verosimiliter in China. (v. v. c.) 
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; ovaries 
7-8. Otherwise with the characters of R. semperflorens, 
from which I nevertheless have no hesitation in sepa- 
rating it. The difference in number of ovaries in this 
division appears constant, and therefore important. 
Mr. Sweet introduced it from the Mauritius, some years 
ago, and it may be the A. pusilla of the catalogue of 
the Botanic Garden there. China is probably its native 
country, as it approaches so very nearly to R. semper- 
Sflorens.
