Rosacce— Rosa. 151 
fruits downy when young, but becoming glabrous towards 
maturity. This group contains only two species, R. ferdéa and 
R. Kamtchatica. The former, a native of the Caucasus, has 
tomentose branches so densely bristling with sharp thorns that 
it has acquired the name of Hedgehog Rose. The leaves 
consist of 5 to 9 dentate leaflets, glabrous above; the flowers 
are large and solitary, of a beautiful rosy purple, appearing 
early, but only slightly scented. No double variety of this 
species has hitherto been reported. 
The Kamtschatka Rose, R. Kamtschdtica, is confined to the 
eastern extremity of Asia, and differs but slightly from the 
preceding, being almost equally spiny, but with the peculiarity 
that the spines are deciduous. The solitary flowers are of a 
deep red colour. No double variety is known of this species. 
These two species are well adapted for planting in masses in 
shrubberies, and also for hedges. 
II. Ros Bracrrits#, or Bracteate Roses.—Dense bushes 
from 3 to 6 feet high, readily distinguished from all other 
Roses by their floral leaves or bracts, and their shaggy ovaries 
and fruits. Only two species are known, both from Central and 
Eastern Asia, and differing so slightly that they may easily be 
confounded one with the other. 
R. palistris, the Marsh Rose of Nepal and China, has white 
solitary flowers supported by a bracteiform involucre of three 
or four leaves. 
R. bracteata, Macartney Rose, a charming little bush, from 
India and Southern China, with roundish-obovate persistent 
shining leaves and solitary white flowers, surrounded by 8-10 
pectinate silky bracts. The beautiful semi-double pure white 
Macartney Rose is said to have originated from seed of this 
species. Two other old but commendable varieties are like- 
wise referred to this species, namely: dba odorata, with large 
full white flowers yellowish in the centre; and Maria Leonida, 
a climbing variety with white flowers, which probably belongs 
to another species. 
The Small-leaved Rose, R. microphylla, which resembles the 
Macartney in more than one respect, naturally finds its place 
here. It isa small compact bush of a beautiful verdure with 
slender flexible branches armed with spines near the insertion 
of the petioles. The leaves consist of 5-9 very small oval or 
roundish perfectly glabrous and shining finely toothed leaf-
