have not seen any specimens in the British collections at 
Kew or South Kensington which are clearly referable to any other 
named eee forms of this group, but it ~ A es rcapeee

that such occur, and have been taken for forms of R. agre 
The three antee Tikely to be found are the tollo wii 
R. Age aii Déségl. This is known from ce rest es the 
group by its small, narrow leaflets, which are often, not 
always, as hairy as those of R. Billietii, that is, more so tia § is 
usual in the group. Tts small, globose fruit, on short, smooth 
peduneles, should sufficiently identify ite Its styles being woolly, 
and its s hit fon or ye oe long-persistent sepals at once 
lets for the group. The ey are more glabrous than thos 
Li. cheriensis Déségl. has its leaflets very like those of R. Jor- 
dant, from which it may be readily fetesuaked oy its large, 
long, ellipsoid fruit, and by its v numerous prickles. It has 
the erect subpersistent sepals of the group, but its —— though 
quite hispid, are hardly so Soslkea as in the other species 
GROUP OF ROSA MICRANTHA. 
The group of 2. micrantha is separated og that of i FCA 
teria by its members having a taller, laxer, and more arching 
habit. Their prickles are stout and equal, leaflets of lager size, 
more oval, and acuminate, peduncles longer, sepals reflexed and 
isadisde styles glabrous and longer, and fruit usually one flk 
urceolate, but exceptions will be found in both groups. For 
example, in some of the micrantha group acicles may be found 
clustered beneath the inflorescence, or on the stems, while some 
micrantha, and only exceptionally so in Eglanteria, in which latter 
also they are seldom so prominent as in micranth e sepals 
are never suberect or more or less persistent, as they frequently 
are in the we group, in fact they are constantly so in 
certain species thereof. 
The glandular hispid pes cera and rather large leaflets, seldom 
cuneate at the base, diff iate the macrantha eee from t those 
of elliptica and agrestis, a var. Briggsit is s to t 
first character, while R. hyst: stria haa the small e 
of the agrestis group.
