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.
