leaves with no visible peculiar reticulation and by its erect habit. 

 5. oYthoclada (S. japonica Hay., Fl. Mont. Form , p. 68) occurs at a 

 little lower altitudes. It is distinguishable l'rom S. japonica by the 

 thinner more acuminate leaves with the impressed costae above. 

 Murrava omphalocarpa Hay., new descr.; Hex glotneratißora Hay., 

 f. 6. 



Celastrüieae. Eiwnymus euphlehiphyllus ; E. peliucidifolius; E. 

 arboricoliis, near E. Spvagiiei, but distinguishable from it by the 

 ovate broader leaves; E. Spraguei, f. 7; E. Tanakae Maxim.; Celas- 

 triis Kusanoi Hay., f. 8, new descr.; C. leiocarpus, very near C. gra- 

 cillinius Hay., but distinguishable from it in having much thicker 

 leaves with impressed veins on the upper surface; C. longe-racemo- 

 sus, PI. 3; C. gracillimuSj very near C. leiocarpus, but differs from 

 it by the much thinner leaves with elevated veins on the Upper 

 surface; C. geminißorus, f. 9; Perrottetia arisanensis, PI. 4, the ge- 

 neric characters agree with Loesener's description, the species is 

 near P. alpestris var. philippinensis. 



Rhatnneae. Sageretia randaiensis, f. 10, very near 5. hamosa 

 Bgt., it may be that Hemsley's record of this species belongs to 

 5". randaiensis. 



Ampelideae. Vitis {Tetrastigrna) arisanensis {V. umbellata Hemsl., 

 var. arisanensis Hay.); V. {T.) shifunensis (F. triphylla Hay.); F. (J.) 

 bioritsensis ( V. dentata Hay.). 



Sabiaceae. Sabia transarisanensis, PI. 5, very distinct for its small 

 and thin leaves not exceeding 5 cm. in length. 



Coviarieae. Coriaria sunimicola, PI. 6, differs from C. sinica Maxim., 

 and C. nepalensis Wall, in having acute or obtuse leaves, never 

 rounded at the base, and in the male flowers without traces of ova- 

 ries; from C. japonica Matsum. by the recurved Stigmas and the 

 presence of staminodes or stamens in the female flowers; from C. 

 intermedia Matsum. by much acuter sepals and larger stamens. 



Rosaceae. Prunus (§ Laurocerasus) niacrophylla S. et Z.; P. trans- 

 arisanensis, very closely allied, if not identical with P. Yamasakura; 

 Rubus acute atißor US , near R. taitaensis Hay., but distinguishable from 

 it in having glandulär setae, besides prickles, on the ander surface 

 of the calyx-cups; R. niingetsensis, f. 11, near the former, but sepa- 

 rable by its longer unarmed peduncles, by the half-closed flowers 

 with the calyx affored with minute prickles on the back but without 

 glandulär setae, and by its leaves which are cordate at the base; 

 R. glandulosocalycinus , near R.pungens Camh. var. Oldhamii Maxim., 

 but distinguishable by the much more densely strongly barbate 

 branches and especially by the densely strongly barbate calyx; R. 

 euphlebophyllus ; R. fraxinifoliolus, near R. fraxinifolius Poir. but 

 separable from it by the smaller leaves and nearly rounded pseu- 

 dosyncarps; R. parviaraliifoHus; R. adenotrichopodus , near R. Swin- 

 hoei Hance, but differs from it in having thinner membranaceous 

 leaves which are nearly glabrous on both sides; in R. Swinhoei, the 

 leaves are usually densely coated on the under surface; R. piptope- 

 talus Hay. new descr.; R. parvifraxinifolius, near R. fraxinifolius , 

 but differs from this in having much smaller leaves; R. parvirosae- 

 folius (R. rosaefolius Smith, subsp. M aximowicsii Hay. non Focke), 

 near R. rosaefolius, but separable from it in having much smaller 

 flowers with glandularly dotted calyx; remarkable for the leaves 

 and the petioles dispersed with glandulär dots; R. parvipungens, 

 near R. pungens Camb. var. Oldhami Maxim., but differs from it in 

 its habit, in its smaller leaves and in the much densely aculeate
