100 THE BRITISH ROSES 
SUBSECTION RUBIGINOSA, 
The only constant feature by which this subsection can be 
distinguished from the Eu-canine is that of its leaflets being 
ensely covered all over the lower surface with nape scented 
glands, which are much larger and more co oe i than is 
considerably more ~adegals and softly hairy. The leaflets of the 
Rubiginose are always biserrate in British species 
t consists of four groups, viz. those of R., ' Eglanteria, Ri. 
micrantha, R. elliptica, and R. agrestis. 
They may be divided in two ways—either by ~ogentreon as 
subgroups FR. rubiginosa ica R. aHiptiodg on the one hand, and 
R. micrantha and R. mn Siete on the other, or eating the four as 
independent groups of equal 
The diagnosis under the first method is as follows :— 
Group of F. Eglanteria. Tufted and compact, stems straight 
and stiff. Main prickles often unequal, though usually of the 
same shape, but there are often some acicles just below the in- 
florescence, and occasionally on stems. Leaflets as a rule rather 
Peduncles rather short, not as a rule longer than the fruit. 
Sepals usually erect or spreading, subpersistent at least till the 
fruit changes colour, pinnate. Flowers sually bright rose, rarely 
é. Styles hispid or villous, stigmas in a s 
Subgroup R£. rubiginosa. Peduncles iiapid, often aciculate. 
Leaflets oval or roundish, obtuse or rounded at apex 
rounded at base, very rarely narrowed.

florescence, none elsew Leaflets medium cles as
