Varieties. The plant varying much in its different native localities, and also
having been long cultivated from seeds in Europe, the varieties are nume-
rous. Some o f those included m the following list appear in our Hortus
Bntanmcus and m Don s Miller as species ; while some hybrids, such as R.
ybnda and R. mtei media, might also have been considered as varieties,
blit we have preferred keeping them apart.

variety is said to have been raised from the seed o f R . Pseùd-ricàcia •
and, according to Dumont de Courset, to have yellow flowers. It
has been common in British gardens since 1820, b u t has not yet
flowered in this country. i«i-ycL

oak the chestnut, the beech, the elm, and most o th e r trees, does not begin to

this siiecies and of several of its varieties, in th e garden of the Horticultural S o -

and linwards in 10 years from the time they were planted. There is, ¡mrhaps, no
