Tshrub about 1 metre high. Flowers in the Arnold Arboretum from the 10th to the middle of June. 



The mixture of hairs with glands on the margins of the petals show the hybrid origin of this plant. Two individual, v 

 anoeared in the Arnold Arboretnm among a number of seedlings of JE. georgiana raised from seeds collected in 1905 by Mr T r 

 Harbison near Stone Mountain in central Georgia. The pubescence on the lower surface of the leaflets suggests that the ^ 

 mrent is M discolor, var. mollis Sargent, but as this pubescence is not more abundant than that found on the leaflets of J* 

 giana,™. pubescent Sargent, it is possible that M.Pavm Linnams may have been the red-flowered parent, both species occ^ 

 in central Georgia. C. S. S.
