II HISTORY AND CLASSIFICATION 21 
greatest break in the hybridisation of Roses of recent 
years. The raiser calls the new class pernetiana. 
The Scotch Rose (R. spinosissima).—The ‘‘ very 
thorny’”’ Rose is a briar native in Great Britain, 
and I have found it growing on the South Downs 
in Sussex. The varieties are semi-double and are 
to be found of almost every shade from white to 
deep crimson. The plant is unmistakable, for no 
other Rose is so thickly covered with small very 
sharp thorns. They are not strong in growth, and 
are best on their own roots, propagated by suckers, 
like the Austrians. Scotch Roses are generally 
used to form a dwarf hedge, which has a pretty 
effect when the little round fragrant flowers are out, 
but these are very soon over. One perpetual form, 
however, has been raised—the Stanwell, a fair 
grower, very sweet, flowering freely from May to 
November. These Roses are thoroughly hardy, and 
will flourish in the poorest soil where no other Rose 
will grow. No pruning, beyond cutting out dead 
wood, is required. 
The Sweet Briar (R. rubiginosa).—This is a native 
briar, growing freely in some parts of England, and 
generally where the soil is light and rather poor. 
The Eglantine, as it is otherwise called, is noted for 
the sweet scent of the foliage, which pervades the 
air for a considerable distance after a shower, in 
spring or early summer. There have been some 
cultivated varieties more or less double and deeper 
or paler in colour than the type, and Lord Penzance 
spent some time and trouble in hybridising them 
with the laudable view of raising a group of good 
Roses with sweet-scented foliage. 
It isa great mistake to plant these ‘“‘ Penzance ”’
