Berberidaceae : Mahonia tikushiensis (PI. 1), and Pittosporaceae : 

 Pittosporunt daphniphylloides (PI. 2j, figures only. 



Caryophyllea. Stellaria reticulivena (1), near 5. micrantha Hay., 

 buth with ovate or nearly cordate leaves, 



Ternstroemiaceae. Thea {Camellia) hosanensis (2), differs from

Rosaceae. Pp. 4—30 contain a key to the determination of the

 of most of the formosan species. Following new names occur in the 

 lists : R. suishaensis (5b ; R. corchorifolius L. var. glaber Matsum.), 

 near R. corchorifolius, but with quite glabrous trinerved leaves. 

 R. arisanensis Hay. var, horishaensis (12c) differs from the type by 

 the leaves which are not at all or very slightly lobed. 7?. Sotnai 

 (14a), near R. piptopetalus Hay., but with hirsute carpels. R. linea- 

 rifolioliis (16a), near R. rosaefolius Sm., but differs from it by the 

 linear leaflets, 



Photinia daphniphylloides (PI. 4 and f. 23), comparable to some 

 extent to P. integrifolia , but differs from it by the villose carpels. 



Caprifoliaceae. Abelia ionandra (PI. 5; A. chinensis Ha5^, non 

 R. Br.) near A. Aschersoniana and A. chinensis; but differs from 

 the former by the much larger leaves, and from the latier by the 

 quite obtuse and shortly apiculate, but never acuminate, leaves. 



Rubiaceae. Nertera nigricarpa (PI. 6). Galiurn Morii (24), remar- 

 kable for its small form with rounded leaves and stipules. G. taro- 

 koense (PI. 7), larger than the preceding species from which it is 

 distinguishable by the quite glabrous, more or less petiolate leaves. 



Ebenaceae. Diospyros Sasakii (PI. 8), near D. Morrisiana Hance, 

 but with notched lobes of the corolla. 



Euphovbiaceae. Euphorbia tnrokoensis (PI. 9), comparable to some 

 extent to E. pekinensis, but has smaller form with perfectly entire 

 leaves and denticulate glands on the involucres. 



Urticaceae. Ficus kaukauensis, near F. Konishii, but separable
