Whitfordiodendron is a genus of flowering plants in the legume family, of Fabaceae. [1] It belongs to the subfamily Faboideae. [2]

Contents

Its native range is from Thailand to western and central Malesia (including Borneo, Malaya, the Philippines and Sumatra). [1]

Description

Species of Whitfordiodendron are scrambling climbers, typically 10–20 m (33–66 ft) tall or even more. The leaves have 2 to 12 leaflets arranged in pairs plus a terminal leaflet. The leaflets are large, generally 4–15 cm (1.6–5.9 in) long or even up to 25 cm (9.8 in) long by 2–9 cm (0.8–3.5 in) or more wide. The inflorescence is a panicle 5–20 cm (2.0–7.9 in) long. In W. nieuwenhuisii, the panicles emerge directly from the main trunk; in the other species they are terminal on the branches. Individual flowers have the typical shape of members of the subfamily Faboideae and are 8–23 mm (0.3–0.9 in) long. The standard petal is 8–18 mm (0.3–0.7 in) long by 9–16 mm (0.4–0.6 in) wide with its inner surface greyish pink or white with flushes of various shades of red. It has a yellow or green nectar guide. The wing petals are 8–18 mm (0.3–0.7 in) long by 2–5 mm (0.1–0.2 in) wide, more or less equal in length to the keel. The keel petals have a short claw. Nine of the stamens are fused together, the other is free; all curve upwards at the apex. The inflated seed pods are 4–10 cm (1.6–3.9 in) long by 2–5 cm (0.8–2.0 in) wide, splitting when ripe to release the 1–3 seeds. [2]

Taxonomy

The genus Whitfordiodendron was established by Adolph Elmer in 1910. [3] The genus name is in honour of Harry Nichols Whitford (1872–1941), an American forester and professor of tropical forestry at Yale University. [4] The Latin suffix of dendron means tree. [5]

It has been treated as a synonym of Callerya ; for example, as of January 2023 the genus was not recognized by the United States Department of Agriculture and the Agricultural Research Service. [6] A molecular phylogenetic study in 2019 reaffirmed its status as a separate genus, [2] and the genus was accepted by Plants of the World Online. [1]

Species

It has four accepted species: [1]

Otholobium swartbergense is a small spreading shrub assigned to the Pea family. All green parts are covered in hairs. It has many slender stems that are woody at their base, alternately set clover-like leaves and heads consisting of 6-15 mauve to purple, pea-like flowers on long peduncles in the axils of the leaves. This species is an endemic of the Swartberg mountains in the Western Cape province of South Africa. It mostly flowers in November and December.

It has up to three stems that carry upright branches in leaf axils near the ground, and have alternately set inverted egg-shaped leaves and lax heads consisting of 12-21 pea-like flowers on long peduncles in the axils of the lower leaves. It differs from most other Otholobium species by the calyx that continues to grow after flowering and the leaf that consists of just one leaflet. It is an endemic of the Eastern Cape province of South Africa near Loerie. It probably flowers August to January.
