slightly hairy beneath. Peduncles glandular. Styles in a 
long glabrous column from a conical disc. Fruit globose 
and flowers white. 
R. seposita Déségl. is more erect, with straight or slightly 
curved prickles. Its leaflets are seldom mu e

combined with that of the ver un-systyla-like prickles 
made the species a very doubtful member of the Stylose. 
SECTION III. PIMPINELLIFOLIZA. 
This section as regards numbers of known species and varieties 
is a small one, about equalling the Synstyle, but its British repre- 
sentatives are even fewer, and are contained in a single aggregate 
species, but it is convenient to deal with its hybrids as separate 
groups of the same section. 
ust be taken as the representative of this group, on account 
of its being an older name than R. pimpinellifolia. The use of 
It is our best defined group, and always easily recognized, 
but being very prone to hybridity, runs by easy stages into 
- rth in the following 
groups (pp. 26, et seq.). On the Continent hybridity with other 
non-British groups occurs. 
_ The nape features of this group are those of the section,

often dentate auricles: une 
globose ; undivided, persistent ; styles short, with a broad 
woolly head of stigmas.
