Marcgravia roonii
Marcgravia roonii, named by Dressler for the Marcgraviaceae specialist de Roon, is a root-climbing vine of premontane and lower montane wet forest from Costa Rica and Panama through Colombia to northwestern Ecuador. Most records sit between 500 and 1500 m in very wet, mild forest, which makes it a good match for a cool-side terrarium with steady humidity.
Where it grows wild
Premontane and lower montane rainforest, often on the wet Caribbean and Pacific slopes of the Talamanca and Choco regions, climbing mossy trunks in shade. 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 150-1880 m with a median of 980 m.
