 tall ; red fruit) .

 Frangula. As the material is rather scanty it is difficult to describe the inflores- 

 cence accurately but it certainly represents a very well marked species. 



2. Rhamnus crenatus Siebold et Zuccarini. See also page 232. 



There are three species, which may be very closely related to R. crenatus or 

 represent only varieties of it, namely R, oreigenes Hance in Jour. Bot. VII. 114 

 (1869); VIII. 312 (1870); R. pseudofrangula L^veUl^ in Fedde, Rep. Sp. Nov. X. 

 473 (1912) and R. cambodianus Pierre apud Pitard in Lecomte, Fl. Gin. Indo- 

 Chine, I. 926 (1912). Of the last I have not yet seen a specimen, but from the
