ROSA HYSTRIX. 129 
74. ROSA hystrix. Tab. 17. 
R. armis ramulorum confertis: majoribus falcatis, fo- 
liolis ovatis, fructibus hispido-muricatis. , 
Hab. in Chine provincia Kiangsi, Staunton; Japonia, 
herb. Lamb. (v. s. sp. herb. Banks et Lamb.) | 
Branches green, flagelliform, armed with nume- 
rous, very small and stiff, unequal, straight prickles, 
a few large, faleate ones being scattered among them ; 
the scars only of the small ones remain on the old 
stems. Leaves distant; stipules very narrow, united 
halfway, their disengaged part deciduous and leaving a 
considerable scar; petioles without down, with a few 
falcate prickles; leaflets 3 together, ovate, flat, shin- 
ing, simply serrated, pedicellated, dark green above, 
pale beneath with a prickly rib. Bractee none; pe- 
duncle and oblong purple fruié bristly with dense, 
needleshaped, stiff prickles and setze; sepals persistent, 
rigid, converging, ovate, pointed, nearly entire, with a 
few stiff slender prickles, some of which are marginal; 
disk flat, fleshy ; styles hairy, included. Flowers large. 
Of this very rare species I have only been fortunate 
enough to examine two specimens; one with fruit, 
from which the figure is taken, in the herbarium of Sir 
Joseph Banks; and the other in flower, but in a very 
imperfect state, in the possession of Mr. Lambert, who 
obtained it, with a considerable number of other Japan 
plants, from a Dutch prize taken in the course of the 
last war. .Its branches are covered with little, short, 
stiff setee and a few larger falcate prickles mixed 
among them. From the ticket of Mr. Lambert's spe- 
cimen it appears that the collector took it for the R. 
canina of Thunberg.
