Palmeria hypotephra is a species of flowering plant in the family Monimiaceae and is endemic to Queensland. It is a woody climber with elliptic to egg-shaped leaves, male and female flowers on separate plants with 4 or 5 tepals, male flowers with 30 to 35 stamens, female flowers with 10 to 12 carpels, and spherical, dark brown to black drupes.

Description

Palmeria hypotephra is a woody climber with stems up to 30 cm (12 in) in diameter, [2] its branchlets covered with star-shaped hairs. The leaves are elliptic to egg-shaped, 60–110 mm (2.4–4.3 in) long and 25–55 mm (0.98–2.17 in) wide on a petiole 5–10 mm (0.20–0.39 in) long. The upper surface of the leaves is more or less glabrous and the lower surface is covered with felt-like white hairs. Male and female flowers are on separate plants and usually have 4 or 5 tepals. Male flowers are arranged in clusters of 13 to 36, 40–75 mm (1.6–3.0 in) long, each flower on a pedicel 7–10 mm (0.28–0.39 in) long, with 30 to 35 stamens. Female flowers are arranged in clusters of 9 to 15, 20–25 mm (0.79–0.98 in) long, each flower on a pedicel 3–7 mm (0.12–0.28 in) long, each with 10 to 12 carpels. Flowering occurs from May to October and the fruit is a dark brown to black, more or less spherical drupe, 5–6 mm (0.20–0.24 in) in diameter. [2] [3]

Taxonomy

This species was first formally described in 1889 by Ferdinand von Mueller in The Victorian Naturalist , who gave it the name Morinda hypotephra from specimens collected on Mount Bellenden Ker, "at a height of about 5,000 ft (1,500 m)" by William A. Sayer. [4] [5] In 1913, Karel Domin transferred it to the genus Palmeria as P. hypotephra. [6] [7]

Distribution and habitat

Palmeria hypotephra grows in rainforest, often near rainforest edges at altitudes, mainly between 80 and 1,550 m (260 and 5,090 ft) in north-eastern Queensland. [2] [3]
