Marcgravia rubra
Marcgravia rubra is endemic to the Dominican Republic, described by Alain Liogier in 1971 from the montane cloud forests of the Cordillera Central and Sierra de Bahoruco at 1200-2200 m. It is one of the coolest-growing Marcgravia, with wild nights of 13-17 C, and suits an unheated, very humid terrarium better than a tropical hot tank.
Where it grows wild
Montane broadleaf cloud forest, climbing mossy trunks in shade where cloud sits on the ridges most afternoons. 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 1200-2237 m with a median of 1340 m.
