ROSA CORIIFOLIA VAR. SUBCOLLINA 101 
ROSA CORIIFOLIA var. SUBCOLLINA. 
Christ in Rosen der Schweiz, p. 191 (1873). 
“Plant greener, more glabrous, naked on the under surface, 
but plainly hairy on the nerves. Calyx pai gceng tt often quite 
reflexed. The resemblance to f. inidhonare Ri ve ripe 
and it is also like var. swbcanina, but its lea flets irowed 
we oF and its almost sessile, large fruit mark it sty 
cae Sen Re Specimens vary greatly, and it is difficult 
to generalize from them. Déséglise does not recognize it as 
distinct from cortifolia, of which it may be regarded as a 
eecorttiis variety, like tmplexa, but with the sepals less 
persis 
I nae ee three examples collected and named by Christ, ae 
of which ar e cortifolia cover of Déséglise’s herbarium 
which shay as obvionsly allied. They agree very fairly well with 
broadly ovoid. A specimen at Kew has loosely reflexed sepals, 
globose fruit on very short peduncles, but the styles are only 
hispid, not in a woolly head. I have seen no eg nae 
British specimens, but as the name has been used in 
recseane I retain it, but pusiiees that it should inelnde 
G implexa.
