There is a small flowering-branch in herb. eset which is 
from Thuillier’s herbarium. It is almost unarme he petioles 
are rather thinly pubescent, quite eglandular and unarmed. The 
leaflets are of medium size, tending to large, rather broadly oval, 
or ovate, acute, not acuminate, practically glabrous above, thinly 
pubescent all over beneath, densely so on veins, which are very 
pointing “ths Fruit ovoid or ellipsoid, soveat small. Sepa 8 
There are six British examples in Heel Déséglise. A specimen 
from Millbrook, Cornwall, collected by Briggs, has remarkably 
ighti acute leaf 
small, goicy beorsens Fo sepals a styles glabrous. Another 
specimen from Egg Buckland, Devon, has just similar prickles, 
but seems otherwise typical. A thie 6 pecimen from Trevol, 
Cornwall, has more hooked prickles and conde less acute leaflets, 
less pubescent above. The leaflets look much more like those of 
R. obtusifolia, but Briggs had labelled it R. dumetorum, which 
name Déséglise accepted. 
A specimen from Thirsk, ee by Mr. Baker, has oblong 
or elliptical leaflets, very thinly hai on upper surface for this 
species ; the petioles also are a erteals thinly hairy. The frui 
is oblong. Another specimen from Sowerby is much more typi- 
cal; it shows the binate prickles well, and its sepals rise above 
the disc. 
An example collected by Woods, near London, has its leaflets 
quite hairy above, much more so than in Mr. aker’s Thirsk 
specimen; but the latter, in forwarding it to erg spe remarked 
that the leaflets are less hairy than in —— e usually calls 
Fi. dwmetorum. Its peduncles are cngeten 
Mos the specimens in Woods’ o wn herbarium have small 
finely serrate leaflets, and slightly hairy pedune
