Hob, Loochoo (Coll.! Imp. Mus. 1876, herb. T. Makino; H. Ruroiwa 

 herb. T. Makino), Nakizin in Isl. Okinawa ($. Tashiro ! herb. Sc. Coll. 

 Imp. Univ. Tokyo, March 1887) ; Prov. Tosa in Isl. Shikoku : Isl. Heshima! 

 (K. Naganuma\ 1886; T. Makino ! June 17, 1887; Y. Yoshinagal herb. 

 T. Makino) ; Prov. Musashi : Tokyo, But. Gard. Koishikawa, cult, from 

 Amami-Oshima, coll. T. Uchiyama (T. Makino ! Nov. 1901). 



This grows on shady littoral rocks of southern Japan, extending 

 between Loochoo Islands southwards, and Isl. Hesliiraa of prov. Tosa in 

 Shikoku northwards. The Heshima plant was at first discovered by 

 myself. The leaves and stem are quite green without any other colour. 

 It comes near to Peperomia dinchjgulensis Miq. Sysf. Piper, p. 122 ; but the 

 leaves to a node are more numerous than in the latter. The plant which 

 Forbes and Hemsley (in Lourn. Linn. Soc. XXVI. p. 366) referr to P. 

 dindygulensis Miq.. probably belongs to my species.
