Maianthemum salvinii is a rare perennial, epiphytic herb[2] found in southern Mexico and Guatemala.

Leaf blades are hairless, lance- to egg-shaped with pointed tips and rounded to long-tapered bases and with flat (not undulating) edges.

[2] 120 to 150 flowers are set in a complex raceme with a main axis 14–35 cm long that is hanging but straight.

Each node has 3 or 4 flowers set on slightly bent-back, drooping pedicels that are usually 15–25 (up to 30) mm long.

The flowers are cup-shaped, with spreading tepals that are 4–4.5 mm long and lavender to pale pink.
