THE HERBARIUM AMBOINENSE. 341 
(iii. 199). This doubt arises from its having been quoted 
as the Myrtus Cumini of Linnaeus ; but the deep division 
of the calyx, very evident in the figure of Rumphius, and 
his having described the real Myrtus Cumini under the 
name Jambolana, removes all doubt from my mind. I 
think that, in the woods of Chatigang and Goyalpara, I 
have seen the tree ; but as I have not seen the fruit, I am 
uncertain, in a genus the species of which are so difficult to 
determine. In 1798 I sent specimens to Sir Joseph Banks, 
under the name of Eugenia calyptrata, and I now shall 
mention what I quoted on the spot, 
Eugenia cymosa, Enc. Meth. iii. I99. 
Jambosa ceramica. Herb. Amb. i. ISO, t. 41.^ 
Bara Jamba Bengalensium. 
Habitat in Camrupas, Tripurse, et Indiae aquosae sylvis. 
Arbor mediocris. Folia magna, coriacea, ovalia vel ovata, 
saepius utrinque obtusa cum acumine ad apicem obsoleto, cos- 
tata, venosa, costis et venis sensim evanescentibus, odore aro- 
matico. 
Paniculae ex anni praeteriti ramulo infra folia nova enatae ra- 
mis tetragonis. 
Calyx quadrilobus. Petala quatuor, apicibus acutis conniven- 
tibus intra stamina incurva insertis, simul caduca, operculum 
peltatum mentientia. 
Fructum non vidi, sed dicitur malum magnitudine aequare. 
Jambosa silvestris Lahunensis, p. 130. 
This seems evidently to be an Eugenia ; but I know no- 
thing farther of it than is here mentioned by Rumphius.

Most of what I had to say concerning this plant has been 
anticipated in the Commentary on the Jambosa ceramica. 
It now remains to give what I consider the true synonyma, 
and a description ; and I must do justice to Burman in
