above, densely so — not at all strongly biserrate, and teeth 
. The petioles are densely pubescent and a goo 
deal glandular. The peduncles and whole fruit are ‘lanl glan- 
dular. The fruit is very small and subglobose. The sepals have 
fallen. Styles villous, rather long. 
_ There are only two foreign specimens, both named with doubt, 
notes from which ‘won therefore be mislea ading. Like the last, 
ie species shows considerable approach to the KR. coritfolia 
oup. 
Foren Species or Suserour IV. 
I know of no foreign species of this subgroup which are likely 
to occur in i aE but, as with the last, occasional examples o 
e Li. rere - core ups might 0) 
belong here. R arcana Déségl. and R. incerta Déségl. (see sub- 
oup ii.) sometimes bays their leaflets sufficiently biserrate to be 
associated with this subgroup. 
GROUP OF ROSA GLAUCA. 
This being a mee group than the last two need be divided 
into two cer only, viz. those with uniserrate and those 
with biserrate cay ath 
Subgroup i. Leaflets uniserrate.

I have adopted R. glauca Vill. as the oldest name for this 
group, its description having been given by te View, 
champs in Desvaux ~— Botanique, ii. p. 809), as 
follows :—‘‘Ovate fruit and peduncles eglandular. Sepals pin- 
natifid. Leaflets oval, gisusous Prickles scattered.” This is 
— insufficient to identify it, and I have not seen any oe 
éimens. I have, therefore, treated R. Reutert God. oh 
ante rather than as a synonym, as most authors regard
