Masdevallia hartmanii

Masdevallia hartmanii (Luer, 1994) is a little-documented species from the eastern Andean foothills of Zamora-Chinchipe in southern Ecuador. The single wild record sits near 900 m, so it is one of the warmer-growing members of the genus: an intermediate-to-warm grower with wet, humid, shaded conditions and only a modest night drop.

Where it grows wild

Wet premontane forest on the Amazon-facing slope of southern Ecuador; almost certainly an epiphyte on mossy trunks and branches in shade, as for most foothill Masdevallia. Nothing specific to this species is published beyond its description.

One wild record near Zamora at about 900 m; the original collection may be somewhat higher, in the 900–1,600 m band typical of Zamora-Chinchipe Masdevallia.
