Maianthemum salvinii is a rare perennial, epiphytic herb[2] found in southern Mexico and Guatemala.[1]

Description[]

Plants grow from 0.75–1 m (2–3 ft)[2] tall from rhizomes. Leafy, straight to arching stems are hairless and ribbed. The type specimen can be viewed at https://www.gbif.org/tools/zoom/simple.html?src=//api.gbif.org/v1/image/unsafe/http%3A%2F%2Fwww.kew.org%2Fherbcatimg%2F189027.jpg

Leaves[]

There are usually more than 7 leaves along the stalk, set 2–4 cm (1–2 in) apart; more closely spaced near the tip of the plant.[2] They have short, 2-5 mm long petioles and are 15–23 cm (6–9 in) long by 5–7.5 cm (2–3 in) wide[2] with evident veins. Leaf blades are hairless, lance- to egg-shaped with pointed tips and rounded to long-tapered bases and with flat (not undulating) edges.[2]

Inflorescence[]

120 t0 150 flowers are set in a complex raceme with a main axis 14-35 cm long that is hanging but straight. The axis is ribbed, and smooth. There are 25 to 40 nodes along the main axis, set about 5 cm apart and set in helix along the main axis. Each node has 3 or 4 flowers set on slightly bent-back, drooping pedicels that are usually 15-25 (up to 30) mm long.

Flowers and fruits[]

The flowers are cup-shaped, with spreading tepals that are 4-4.5 mm long and lavender to pale pink. Stamens are inserted at the tepal bases. Fruits are rounded, 8-10 mm across, ripening to red. Flowering is in March; fruits are retained into January or February.[2]

Distribution[]

The distribution of Maianthemum salvinii is not well documented,[3] but is reported from Guatemala and southeast Mexico.[1] It is thought to be rare.[2] The site in Guatemala that is was found has been developed, so is unlikely to have persisted there.[2] It has also been documented adjacent to Guatemala, in the mountainous Tacaná-Boquerón region of Chiapas, Mexico.[4]

Habitat and ecology[]

Maianthemum salvinii Is an epiphyte of primary forests.[2] In Guatemala it was found in forests on white sand slopes at 1800-2000m.[2] It has also been found in the mountainous Tacaná-Boquerón region that has extensive montane cloud forests.[4]
