ROSA MICRO PH YLLA 
from Canton by Dr. Roxburgh. Thence it was conveyed to this 
country, where it flowered for the first time in Colvifs nursery in 1824. 
Later it was thriving in Curtis’s Glazenwood Nursery at Coggeshall 
in Essex. It had long been cultivated in China and Japan, but the 
Rosa microphylla of the Simla forests is not our plant. Till 1862 only 
the double form had been known in Europe, but in that year the single 
form was collected by M. Maximovicz on the shore of Lake Hakone 
in central Japan, and it was from these plants that Crepin published 
his excellent description. Dr. Savatier also found this Rose on the 
same spot in 1871, and two years later Dr. Shearn collected it at 
N ew-Kiang in north China. 
Three forms are figured in the Phonzo Zoufon J one with single 
white flowers, a second with single red flowers, and a third with double 
red flowers. There is an excellent figure representing the double red 
form in the Botanical Magazine } 
In its general appearance this charming Rose somewhat resembles 
the Macartney Rose, and forms a most attractive object in the garden. 
In France it is often called the Rose Chataigne from the resemblance 
of its fruit to a sweet chestnut. Its leaflets, eleven to fifteen in number, 
are more numerous than in any other Rose yet known. At Tresserve, 
in Savoy, it blossoms from May to December, and its widely open 
flowers, which often measure five inches across, are succeeded by large, 
thorny, sweet-scented fruits. Although easily increased by seed, cut- 
tings or suckers, it is still comparatively rare in English gardens. 
An interesting hybrid of Rosa microphylla x rugosa originated in 
the garden of the Institut Botanique de Strasbourg. It was found 
growing at the foot of a plant of Rosa microphylla and clearly shows its 
parentage, having the straight branches of Rosa microphylla , with its 
globular buds and large prickly fruits. Its general habit and appear- 
ance suggest the rugosa influence.
