Stem long, sarmentose ; prickles small, hooked, scattered, uniform. Leaflets 
5-7, oblong, acute, 1-2 in. long, rather firm, glabrous, green, simply toothed ; petioles 
naked ; stipules free, linear, small, deciduous. Flowers very small, arranged in 
corymbose panicles, very numerous ; ultimate branchlets corymbose, not umbellate ; 
pedicels short, naked. Calyx-lobes ovate, acute, J in. long, simple or slightly com- 
pound, naked on the back. Petals obovate, white, but little longer than the sepals. 
Styles free, glabrous. Fruit globose, naked, bright red, less than j in. in diameter 
when dried ; sepals deciduous. 
This interesting new Rose is allied to Rosa Banksiae Ait, which 
o 
it resembles in its habit, leaves and stipules, but it is abundantly dis- 
tinguished by its numerous very small flowers, arranged in corymbose 
panicles, of which the ultimate branchlets are corymbose, not umbellate. 
Its original describer, Dr. Focke of Bremen, compares its inflorescence 
to that of a Sorbus or Viburnum. It was found by Mr. E. H. Wilson 
in the western part of the province of Hupeh in central China.
