ARBORETUM NOTES. 
RANUNCULAGEE. 
wood is composed almost entirely of large dotted 
vessels, appearing in the transverse section, as 
large open pores, with a very small proportion of 
ordinary woody fibre. It is found in a number of 
wedge-shaped portions, radiating from the pith ; 
and in the old stems these wedges separate from 
one another (seemingly through the decay of the 
intervening medullary rays), and remain quite 
loose, held together only by the bark which covers 
them. 
CLEMATIS MONTANA. 
Loudon, v. I. 245. 
Several flourishing plants at Barton. It is now 
(June, 1860) in full blossom; a very beautiful 
climber, seemingly quite as hardy as Clematis 
Flammula, and of a more vigorous and luxuriant 
habit, more like Vitalba ; grows rapidly, and bears 
a rich profusion of large and brilliant white flowers, 
very ornamental. Appears to have suffered but 
slightly from the late long and severe winter. The 
flowers in cultivation have very often six sepals, 
almost as often as four, which is the normal 
number; sometimes five, but less often. 
(May, 1861). This Clematis is now coming out 
well into blossom, having apparently suffered little, 
if at all from the late terrible winter. 
(November, 1861). It flowered well this summer 
and made a very handsome show.
