FLORA OF THE ISLAND OF SHIKOTAN, 461 
and do not bear glands on the tips. The glandular hairs also occur copiously 
intermixed with the prickles. There is no room for doubt that this form 
has a closer relationship to X. phoenicolasius, from which our plant is distin- 
guished by having paler-coloured prickles and spreading or reflexed calyx- 
segments. The leaf is usually trifoliate, 5-foliolate leaves occurring but 
seldom in this form. 
In Hontó another form of the same species, known as var. nipponicus, is not 
uncommon. Palibin mentions the occurrence of this form in Corea (Consp. 
Fl. Cor. i. p. 78). Although I have not been able to examine the specimen 
from Seoul, which is referred to by this author, the other one collected by 
Sontag at Van-Tang-San is not identical with Rubus deus var. nipponicus, 
Focke, but is, in fact, A. triphyllus, Thunb., which is known from Corea 
under the name of R. parviflorus in Palibin’s book.
