Discussion:

Ugni oerstedii Berg, Linnaea 27: 389. 1856.

To this I refer all material from the high volcanoes of Costa Rica. Both leaves and flowers are unusually large for the species, and the broad large calyx-lobes are distinctive; these occasionally are narrowly rather than broadly triangular, but then are larger than in other varieties with narrow lobes.

Amshoff (Ann. Missouri Bot. Gard. 4 5 : 194-196. 1958) reports "a closely alhed" species, Ugni warscewiczii Berg, from western Panama. From her description of the sepals ("lanceolate, obtusish, about 5 m m . long"), I suppose the Panama plant is more like U. myricoides var myricoides than like U. myricoides var oerstedii.
