Marcgravia polyantha
Marcgravia polyantha is a wide-ranging root-climbing vine of the Brazilian Atlantic forest and the eastern Andean slopes of Peru and Bolivia, recorded from sea level to 2800 m. The shingle-leaved juvenile stage climbs damp trunks in shaded, humid forest and is the form collectors grow on a terrarium background. It tolerates cooler nights than most lowland Marcgravia, which makes it forgiving in an unheated room.
Where it grows wild
Humid Atlantic rainforest and Andean montane forest, climbing tree trunks and mossy rock in shade beneath the canopy. 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.
Records span 4-2800 m with a median near 1100 m; the Brazilian populations are mostly below 1000 m, the Peruvian ones sit at 2000 m and above.
