1924] NAKAI, RAPHIOLEPIDIS ET ERIOBOTRYAE SPECIES 67 



Raphiolepis rubra var. lanceolata Nakai, var. nov. 



Raphiolepis Loureiri Sprengel, Syst. Veg. n. 508 (1825), excl. syn. — Roeraer 

 Syn. Monog. in. 114 (1847), excl. syn. 



Folia lanceolata. Petala ovata vel subrotundata. 



Sprengel considered this to be the Crataegus indica of Loureiro and 

 wrote that this species had lanceolate leaves and Roemer followed him, 

 but Loureiro's description — "Folia cuneiformi-ovalia — apice ovata basi 

 attenuate" — shows that this (his) type is different and belongs to Raphio- 

 lepis indica. 



China? 



Raphiolepis rubra var. minor Nakai, comb. nov. 



Raphiolepis umbellata var. minor Makino in Tokyo Bot. Mag. xvi. 14 (1902). 

 Raphiolepis minor Koidzumi in Tokyo Bot. Mag. xxui. 171 (1907); in Jour. 



Coll. Sci. Tokyo, xxxiv. art. 2, 73 (Consp. Rosac. Jap.) (1913). 

 Inflorescentia contracta; petala obtusa. 



This is known only in Japanese gardens, especially in temple grounds 



near Kyoto. I suspect that it was brought from China as Gingko biloba, 



Magnolia denudata, Magnolia liliiflora, Forsythia suspensa and other 



plants have been, but the history is unknown. It is strange that this 



form only was introduced into Japan when there are so many varieties 



of both Raphiolepis indica and R. rubra in China. 



Plantae mihi ignotae: 



1. Raphiolepis indica var. latifolia Cardot in Lecomte, Not. Syst. III. 



380 (1818). 



2. Raphiolepis indica var. mekongensis Cardot 1. c. 



Berthold Seemann adopted Opa as the generic name of Raphiolepis 

 for reason of its priority. Opa includes two species: Opa odorata Loureiro 

 which is Eugenia Millettiana Hemsley and Opa Metrosideros Loureiro which 

 is Raphiolepis indica. The type specimens are said to be in the British 

 Museum. From the generic description of Opa "calyx lacinis rotundatis, 

 petala subrotunda, filamenta corolla duplo longiora," we can readily 

 understand that it was based on both plants. Now Opa odorata is the 

 first species, so we must take it for the type of the genus. The generic 

 name Opa is thus a synonym of Eugenia (or Szygium in a restricted sense) 

 partly and that of Raphiolepis partly.
