. On rivulets, near the Blue mountains: Pensylvania. b. 
May-—July. v.v.—This beautiful species has, to my 
knowledge, not yet been introduced into the gardens.. 
I have only seen it in its native place and in the gar- 
deu of Mr. Jobn Bartram, near Philadelphia, whose 
father introduced it many years ago. lt rises from ten 
to twenty feet high, and forms, with its elegant fo- 
liage and large abundant rose-coloured flowers, the 
. finest ornamental shrub I know. The flowers are not 
so much pubescent as the rest of the other species; 
the scales of the flower-buds are large, yellowish- 
brown, surrounded with a fringed white border.
