822 Mr. C.C. Babington on the British Rubi. 
of the ‘ Rubi Germanici’; sometimes, in the variety pseudo-casius 
of the same work, that leaflet is deeply three-lobed and slightly 
cordate below ; both may be found upon the same stem. ‘The la- 
teral leaflets are often deeply divided into a larger and a smaller 
lobe, but I have never seen true R. ca@sius with the lobes sepa- 
rated into distinct leaflets, neither do authors mention any such 
case. 
Hedges and thickets. June to August. 
Obs. The ternate leaves, of which the lateral leaflets are strongly 
lobed below, and the terminal leaflet rounded but scarcely ever 
at all cordate at its base, all of them coarsely serrate, inciso-ser- 
rate or even lobed ; the very slender prickles on the round stem ; 
the simple panicles and glaucous fruit, which usually consists of 
very few large drupes ; distinguish this plant from all the pre- 
ceding, except R. tenuis, in which the prickles are much stronger 
on all parts of the plant, and there are no sete on the barren 
stem.
