ROSACEAE. — ROSA 319 



riety from the typical wild plant. Rosa laevigata is cultivated in Japan, but is not 

 wild there, although it has been enumerated as a Japanese plant by certain bot- 

 anists. It was brought to North America early in the 17th century and soon 

 becoming widelj^ naturalized was first described as an American plant. 



The first mention of Rosa laevigata Michaux in western literature is to be found 

 in Plukenet, Amalth. 185 (1705) under the name " Rosa alba cheusanensis foliorum 

 marginibus et rhachi medio spinosis"; his specimen is preserved in the British 

 Museum. The Rosa sinica, /3 Braajniana Regel {Tent. Ros. Monog. 43 [1877]}, 

 based on Braam's figure which Miss Willmott (Gen. Rosa, I. 118 [1911]) says is 

 " doubtless a hybrid," is Rosa bracteata Wendland, a species which is common in 

 the coast provinces of China south of the Yangtsze River. 



Rosa Argyi L6veill6 (in Bull. Sac. Bat. France, LV. 56 [1908]) from Kiangsu, of 

 which we have seen no specimens, is considered by the author to be a hybrid 

 between this and the following species. Judging from the description, however, 

 it does not appear to be specifically different from R. laevigata.

Rosa microphylla, a glabra Regel, Tent. Ros. Monog. 38 (1877) ; in Act. Hort. 

 Petrop. V. 321 (1878). 



This species was originally described from plants cultivated in the Botanic 

 Garden at Calcutta and was said to have been introduced from China. It is 

 probable that Rosa centifolia Loureiro {Fl. Cochin. 323 [1790]) belongs here.
