 Korea : in silvis montis Toroho districtus Kainan, Zenla-austr. (T.

The discovery of this species in Korea is an importance for the 

 distribution, because the species has been determined by Mr. T. Makino 

 as a hybrid between Pyrus sinensis (P. serotina of present) and 

 P. dimorphophylla. The appearance of P. Uematsuana in a whole 

 could be considered as a hybrid of the above two, so Mr. Makino 

 has stated. As a matter of fact, P. dimorphophylla does not grow 

 in Korea, but P. Fauriei which resembling P. dimorphophylla very 

 closely grows there — being shrub with leaves of different shape. The 

 specimen I found at the Toroho Mountains was only one of an 

 immense size. Besides there are also P. Fauriei and P. serotina 

 growing in these mountains. The situation being thus, if P. 

 Uematsuana is a hybrid, it must be hybrid of P. Fauriei and P. 

 serotina. Suppose P. Fauriei was a parent instead of P. dimor- 

 phophylla, could the hybrid be similar to P. Uematsuana? It is a 

 problem for genetic study. However, as far as I am concerned, I 

 doubt that the opinion for hybrid would be entertained merely as 

 a fancy. 



664) Meliosma hachijoensis, Nakai sp. nov. Pinnatae. 



Species inter M. rhoi folia et M. Oldhami intermedia, praesertim 



posteriore accedit, sed a priore petiolis rufo-pubescentibus foliolis 

 supra surdioribus, et a posteriore petiolis pilosioribus foliolis cras- 

 sioribus et lucidioribus, serrulatulis paucioribus margine pilosioribus 

 distincta. 



Arborea 5-6 metralis. Ramus robustus. Cortex ramorum bien- 

 nium rubescenti-fuscus lenticellis fuscis punctatus, hornotinus pallide 

 subalbescenti-fuscus lenticellis angustis v. oblongis fuscis punctatus. 

 Gemmae dense fusco-villosae. Petioli 3-5 cm. longi cum rachibus 

 foliorum fusco-pubescentes basi incrassati. Folia praeter petiolos circ.
