in Hermann's herbarium is Eugenia jambolana Lam. The 

 specific names, cumini and jambolifera, were interchanged 

 between Eugenia and Act onychia. 



I can see no reason for considering Jambosa ceramica Rumph. 

 to be other than Eugenia cumini (Linn.) Merr. Linnaeus placed 

 it under Myrtus cumini Linn., and Willdenow placed it under 

 Calyptranthes caryophyllifolia Willd,, both synonyms of Eugenia 

 cumini (Linn.) Merr. Lamarck, Encycl. 3 (1789) 199, placed 

 it under Eugenia cymosa Lam., a species based primarily on 

 specimens from the Isle of France. At any rate Jambosa 

 ceramica Rumph. is not Eugenia cymosa Lam. as Lamarck's 

 species is currently interpreted. 



EUGENIA JAVANICA Lam. Encycl. 3 (1789) 200. 



Jambosa silvestris parvifolia Rumph. Herb. Amb. 1: 129, 2: t. UO. 



In all copies of the Herbarium Amboinense, t. 1+0 of volume 

 one and two are transposed ; the plate in volume one corresponds 

 to Radix deipariae spuria Rumph. Herb. Amb. 2: 127 and is 

 Gmelina villosa Roxb., while the plate in volume two corresponds 

 to Jambosa silvestris parvifolia Rumph. Herb. Amb. 1 : 129 and 

 is the species here considered (see under Gmelina villosa Roxb., 

 p. 454). Perhaps the chief reason why the description and 

 figure as given by Rumphius have never been properly placed 

 was due to this transposition of the plates, which is mentioned 

 in the Auctuarium (Herb. Amb. 7: 3). The illustration seems 

 to me to be a fairly typical representation of Eugenia javanica 

 Lam. ; and I have made this reduction with considerable confi- 

 dence, although I have seen no botanical material from Amboina 

 that I would refer to this species.

 Jambosa litorea Rumph. Herb. Amb. 3: 81, t. 53. 

 Amboina, Amahoesoe and Hoenoet, Robinson PI. Rumph. Amb. 193, 196, 

 September and October, 1913, on cliffs near the seashore, locally known as 

 jambu ayer and jambu puti. 



No previous reduction of Jambosa litorea Rumph. has been 

 suggested, other than Henschel's statement that it pertained 

 to the Myrtaceae. The description and figure manifestly per- 

 tain to Eugenia, a species in the group with Eugenia javanica 

 Lam., E. colubcob C. B. Rob., and E. subglauca Koord. & Valeton. 

 The Amboina specimens, which certainly represent Jambosa 

 litorea Rumph., differ from the Javanese Eugenia subglauca 

 Koord. & Val. in their leaves, which are more rounded at the
