seen them beiry as Déséglise says they are when young. h 
fruit is usually large and ovoid, sometimes ellipsoid, but rarely 
globose, and I cannot see that the calyx-tube is globose, the shape 
assigned to it and to R. coriifolia to separate them from their 
allies. The styles are villous. 
There are three Britishexamples. A pee from Wazrleigh, 
Devon, yee by Briggs, and labelled by him “RB, dumetor um,’ 
has | caflet of medium size, truncate below, ‘aiid to tip, able 
serrate, tooth with long poe thinly hairy all over beneath, an 
some leaflets thinly hairy above. Fruit not formed. His specimen 
from Weston Mill, South Bevca: labelled by him “ R. platyphylla,” 
though queried by Déséglise, seems to me to agree much more 
ere with ane description of that species than does the Miran in 
plant. A specimen by Mr. Baker from Thirsk, labelled “ 2. platy 
deh ” has large elliptical leaflets glabrous above, hairy on eae 
benea No fruit. Styles rather densely hispid. Its flowering- 
beanghes are unarmed, a character relied upon by Crépin in his 
key to separate R. spherocarpa Pug. from R. platyphylla Rau, but 
not mentioned by any other author. 
ForeIcN Species or Superovur I.* 
The following, from their Continental distribution, are likely to 
be found in Britain :— 
Styles haat or monies. but not woolly :— 
globos 
R. Seineectiienc Pug. Leaflets large, broad, oS hairs 
almost confined to midrib. Petioles nd flowering- 
branches almost so. Flowers white. Fruit large, sub- 
globose. Styles hispid or thinly so. (Near R. platyphylla 
and &. platyphylloides. ) 
Fruit ovoid :— 
fi. platyphylloides Déségl. & Rip. Leaflets medium, oval, 
hairy on nerves and occasionally all over, but not glaucous 
beneath. Fruit of medium size, ovoid. (Like a small 
fi. platyphylia, but leaflets less hairy, not glaucous beneath.
