Marcgravia punctifolia
Marcgravia punctifolia is a little-known root-climbing vine of the Guiana Shield, described by Dressler and recorded only a handful of times in Bolivar state, Venezuela, and northern Brazil. The epithet refers to dotted leaves. Almost nothing is published on its ecology, so the profile below is built from the two known sites and what the genus needs: a warm, humid, shaded climbing surface.
Where it grows wild
Lowland to upland evergreen forest of the Guiana Shield, presumably climbing trunks in shade like its relatives. Like the rest of the genus it is a root-climbing hemiepiphytic vine with two shoot forms: juvenile climbing shoots press small shingle leaves flat to bark or rock, and only mature free-hanging shoots carry the larger leaves and the pendent umbel with nectar-cup bracts. Growers keep it in the juvenile shingling stage on a damp vertical surface.
The one georeferenced site sits near 680 m on the Gran Sabana margin; the true elevation range is unknown.
