HAB. Mt. Arisan : Mingetsukei, leg. B. HAYATA et TAKEO ITO, Mart. 1914. 

 Very near Rubus aculeatiflorus HAYATA, but separable from it in having 

 much longer unarmed peduncles, in the half-closed flowers with the calyx 

 which is afforded witli minute prickles on the back but quite destitute of any 

 glandular seta, and by the leaves which are cordate at the base ; in It. acu- 

 leatiflorus HAYATA, the leaves are truncate at the apex of the petioles and 

 slightly cordate towards the outer sides. 



Rubus glanduloso-calycinus HAYATA sp. nov. Suffrutex ; rami et 

 ramuli teretes flexuosi, cortice subkevi rubro-fulvescenti sub lente minute 

 lenticellato, lenticellis longitudinaliter dispositis, sub lente tenuiter striati 

 remote grosse aculeati, aculeis cuspidiformibus 5 mm. longis sursum subteretibus 

 deorsum latere complanatis basi dilatatis, partibus dilatatis 2^ mm. latis
