Description
Plants grow from 0.75–1 m (2–3 ft)[2] tall from rhizomes. Leafy, straight to arching stems are hairless and ribbed.
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 to 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.
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 it 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]
