RUMPHIUS'S HERBARIUM AMBOINENSE 



Linn. Eugenia mindanaensis C. B. Rob., described from Min- 

 danao specimens, is manifestly identical with Eugenia aquea 

 Burm. f. This reduction had been indicated by Doctor Robin- 

 son in the herbarium of the Bureau of Science before his de- 

 parture for Amboina in June, 1913. 



EUGENIA CUM IN I (Linn.) comb. nov. 



Myrtus cumini Linn. Sp. PI. (1753) 471. 



Eugenia jambolana Lam. Encycl. 3 (1789) 198.

Eugenia obtusifolia Roxb. Hort. Beng. (1814) 37, nomen nudum, Fl. 



Ind. ed. 2, 2 (1832) 485. 

 Syzygium jambolanum DC. Prodr. 3 (1828) 259. 



Syzygium cumini Skeels in U. S. Dept. Agr. Bur. PI. Ind. Bull. 248

 Jambolana Rumph. Herb. Amb. 1 : 131, t. h2. 



This species is not represented in our Amboina collections, but 

 Rel. Robins. 2UUS from Macassar, Celebes, July 11, 1913, is 

 typical Jambolana Rumph. Linnaeus, in Stickman Herb. Amb. 

 (1745) 7, Amoen. Acad. 4 (1759) 119, reduced Jambolana, 

 with doubt, to Jambolifera pedunculata Linn., in which he was 

 followed by Burman f., Lamarck, Loureiro, Murray, and Pritzel. 

 It has been cited by various authors under Eugenia jambolana 

 Lam., Calyptranthes jambolana Willd., Eugenia obtusifolia 

 Roxb., and Syzygium jambolanum DC, and is the type of var. 

 p of the last in DC. Prodr. 3 (1828) 260. 



I am now of the opinion that Myrtus cumini Linn, supplies 

 the oldest valid specific name for this species. Jambolifera 

 pedunculata Linn., Sp. PL (1753) 349, was based primarily 

 on Fl. Zeyl. 139, and the specimen in Hermann's herbarium 

 is Acr onychia laurifolia Blume.* The description in Flora Zey- 

 lanica applies to Acr onychia laurifolia, not to Eugenia cumini, 

 but the name and the synonyms Jambolones and Jambolons 

 apply to Eugenia cumini. It is clear, however, that Linnaeus's 

 later conception of Jambolifera pedunculata was as Eugenia 

 cumini rather than Acr onychia laurifolia, as shown by his reduc- 

 tion of Jambolana Rumph. and the reference to Plukenet added 

 in the Mantissa 2 (1771) 371. I believe, however, that the 

 original description and specimen should stand as representing 

 Jambolifera pedunculata Linn, and that it goes with Acronychia 

 laurifolia Blume as a synonym. Myrtus cumini Linn, was based 

 wholly on Fl. Zeyl. 185, and the description and the specimen
