(284) NEW OR LITTLE KNOWN PLANTS OF JAPAN. 



Besides these, B. nepalensis, Spreng. (HIragi-nanten), and B. Fortune! , 

 Lindl. (Hosoba-hiragi-nanten) are seen in gardens; but they are Chinese 

 species and not indigenous to Japan. The specimens I collected on Mt. 

 Yahazu in the province of Tosa, on August 8, 1888, are different from all 

 those mentioned above. As the specimens have fruit only and no flowers, it is 

 impossible to determine accurately their characters; but they are, I think, of a 

 new species. They are allied to B. Thunbergii; but the branches of the 

 latter have prominent ridges, while those of the present species are terete. 

 The leaves of the latter are also much smaller. The terete branches are like 

 those of B. Tschonoskiana, but the latter has no spines, which is not the case 

 with the present species. I have, however, not yet seen specimens of B. 

 Tschonoskiana. The following is a brief and very incomplete description of 

 the present species:— 



Branches terete. Leaves broadly ovate or obovate, entire, obtuse at the 

 apex, narrowed at the base into winged petioles, smooth, pale on the under 

 surface, 1-3 inches long including the petiole, 4 lines to i inch broad; 

 petioles in large leaves about J inch long, in small leaves scarcely i line 

 long. Spines simple, 3-6 lines long. Racemes several-flowered. Berries 

 oblong-obovate, 3 lines long; pedicels 6-10 lines long.
