SAXIFRAGZE. 
It forms a very dense bush, a great number of Does 
stems rising up close together, at first ere¢t and 
wandlike, toward their tops much branched and 
arching. The leaves are remarkably rough ; 
flowers of a beautiful pure white, much like those 
_ of some Saxifrage on an enlarged scale; resembling 
also those of Philadelphus, but the stamens are 
only ten, and their filaments broad, flat, ending in 
three points, of which the middle one bears the 
anther. In general form and mode of growth 
(‘‘ habit”) this is very like a Philadelphus, but it is 
remarkable for the degree in which the stems and 
older branches throw off their bark in winter— 
which I have not observed in the genus just 
mentioned. The bark exfoliates and comes off in 
large quantities, hanging loose on the stems in 
broad ragged strips, which show their interior of a 
bright cinnamon colour, and sometimes they take 
the form of quill-like rolls. The new bark, exposed 
by this exfoliation, is likewise cinnamon coloured ; 
so that altogether the winter colouring of the bush 
is rather rich and warm.
