Angraecum humbertii

A little-documented Angraecum from south-eastern Madagascar, known from only a handful of collections. With nothing published on its cultivation, grow it like other mid-elevation Malagasy angraecums: bright filtered light, warm days, distinctly cooler and drier winters.

Where it grows wild

Collections come from the mountains of the south-east, around 800–900 m, where humid forest meets drier vegetation; it is presumably an epiphyte or lithophyte like most of its genus, but the exact habit is not documented here.

Sites given at 800–900 m; the climate grid cells are lower (220–430 m) and the temperatures were adjusted for altitude.
