Eugenia baruensis (Jacq.) Jacq., Coll. 3: 183. Apr 1790

The name Eugenia baruensis rests nomenclaturally on E. carthagenensis var baruensis, as in publishing the binomial Jacquin cited "Jacq. amer. pag. 153," referring by implication to the varietal name pubhshed in 1763. There is an ample specimen from Jacquin's herbarium, which I studied at W in 1966, and which is evidently the same species as that described under the name of E. baruensis in 1790: the description is clear and detailed. The species is said to flower freely in cultivationbut to set fruit rarely. The specimen is labelled "Eugenia baruensis," and "Hort. B[ot.] Vind." Another specimen at Vienna, marked "ex horto schoenbrunn. 1814," is from the herbarium of Jos. Boos, and is so similar to the Jacquin specimen that it may well have come from the same plant. I cannot distinguish these specimens from West Indian material of E. axillaris, whereas they differ in a number of respects (as set forth in the key in Fieldiana Bot. 29: 421. 1963) from Panamanian and other Central American material of E. acapulcensis Steud., the only other species with which they might be confused. Thus it seems there is little doubt about the identity of the plant that was cultivated at Schoenbrunn in Jacquin's time under the name of E. baruensis. Whether or not this plant that began to flower in Vienna some time before 1790 is the same plant that Jacquin observed near Cartagena before 1760, can not readily be determined. Probably the only way to learn the identity of E. carthagenensis var baruensis is through the study of the myrtaceous flora of the region of Cartagena. The var baruensis was described from "sylvis maritimis," and in spite of the changes made in the vegetation by man, one might expect to find most of the species of the original coastal forests still existing.
