216 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Rosa canina , L. frondosa x coriifolia. “ Between frondosa and 
coriifoliaR — J. G. Baker. Near Ashbourne, Derbyshire, September, 
1888.— W. R. Linton. “Would not this best come under implexa , 
although the styles are nearly glabrous ? ” — W. Moyle Rogers. 
“ Probablement une var. du Rosa canina du groupe R. lutetiana , 
Leman. ” — Crepin. 
R. canina , L., var. coriifolia (Fries). Form with setose sepals. 
Berriedale, Sutherland, July, 1888. — W. R. Linton. “Yes, if the 
sepals are really subcristate ; a point left uncertain by my specimen.” 
— W. Moyle Rogers. “ Appartient au R. coriifolia , Fries. C’est une 
variation a dents irregulieres doubles, triples ou simples.” — F. Crepin. 
R. , peduncles and sepals setose, leaflets of urbica ; 
named by Mr. Baker u Reuteri, with glandular sepals.” Near 
Hognaston, Derbyshire, September, 1888. This form by its prickles 
recalls tomentosa , whilst it has the leaflets of urbica , and in other 
respects it is divergent from typical Reuteri ( =glauca Vill), which 
occurs in a few places in this district. — W. R. Linton. “ Pubescence 
extremement faible ; petiole un peu pubescent; cote medionne un peu 
pubescent ; parfois q. q. rares poils sur les nervures secondaires. Peut- 
etre une variete du R. coriifolia , Fries.” — F. Crepin. 
R. stylosa, var. pseudo-rusticana , Crep. Leigh, 4th August, and 
Beer Hackett, 31st August, both in Dorset; and also in fieldhedge 
between Flagler’s Hole and Sedgehill, S. Wilts., 1st September, 1888. 
Seen only in hedges. A new white flowered glabrous-leaved form of 
R. stylosa , thus named for me by M. Crepin in March last, after 
having been sent by me to the club for distribution two years before, 
labelled R. virginea , Rip. For description &c., see ‘Jour. Bot.,’ 
January, 1889. — W. Moyle Rogers. 
R. stylosa , Desv., var. leucochroa (Desv.). A very strongly growing 
rose, abundant on the banks of marsh ditches in the lowlands near 
Worle, North Somerset. When in early bloom the column of styles 
is only prominent in the primordial flowers ; but in fruit this character 
is well marked throughout. 12th September, 1888. — J. Walter 
White. “Pubescence a peu pres bornee a la nervure mediane ; 
petioles glabrescents. C’est une var. du R. stylosa voisine du R. 
rusticana , Desegl.” — F. Crepin. 
R. leucochroa , Desv. I have been urged to write a note and ask 
for its insertion in this report on the plants which I sent to the club 
thus named last year as new county records for Dorset and S. Hants. 
The members who received those specimens may well have doubted 
whether they were worth keeping when they read M. Crepin’s note in 
the Report — “ This is a stylosa form, but it is impossible to say 
whether it should be placed under R. systyla Desv. or R. leucochroa 
Desv.” It may interest these members therefore to learn that in 
March, 1888, without having heard of this note (already sent to Mr. 
Nicholson, I suppose), I forwarded nine sheets of specimens to 
M. Crepin, all labelled R. leucochroa — eight being from Devon 
localities, and the ninth the plant from Dorset which had been sent to 
the Club — and that M. Crepin most kindly wrote a separate note for 
each sheet, confirming the name leucochroa , with the qualification in
