Garcinia isthmensis Mouzinho, sp. nov.
Diagnosis:—Garcinia isthmensis is vegetatively similar to G. magnifolia due to its elliptical to elliptic-oblong shape
and size of the leaf blades (≥ 19 cm long), but differs from it due to its slightly verrucose branches (vs. smooth in G.
magnifolia), conspicuous exudate canals (vs. inconspicuous in G. magnifolia), staminate flowers with 40–55 stamens
per flower (vs. ca. 30 stamens in G. magnifolia), non-rostrate fruits (vs. rostrate in G. magnifolia) and fruit pedicels of
33.5–44 mm long (vs. 7–10 mm long in G. magnifolia).
Etymology:—The epithet refers to the Panama isthmus, that connects Meso- and South American regions.
