Anogeissus acuminata is a species of tree in the Combretaceae and has been called axlewood,[citation needed] buttontree[2] or Burmese-derived yon[3] (Template:Lang-my-name-MLCTS; IPA: [jṍʷ]) in English. It is now considered a synonym of Terminalia phillyreifolia (see #Taxonomy).

A medium-sized tree found in both primary and secondary tropical and sub-tropical forests, it may be one of the dominant species of deciduous forests of Vietnam;[4] it is recorded from the rest of Indochina, Bangladesh, India , Myanmar and Yunnan in China. In Yunnan it is found in rocky limestone areas, near sea level to 700 m.[5]

Besides timber uses, the bark of this species has a high tannin content.

Taxonomy

Reference has been made to the varieties:[6]

  • A. a. var. fischeri (M.G.Gangop. & Chakrab.) M.G.Gangop. & Chakrab.,
  • A. a. var. lanceolata Wall. ex C.B.Clarke occurring from India to Vietnam,
  • A. a. var. phillyreifolia (Van Heurck & Müller Argoviensis) Kurz, is "apparently restricted to Myanmar".

Plants of the World Online now refers to this species as a synonym of Terminalia phillyreifolia (Van Heurck & Müll.Arg.) Gere & Boatwr.[7] per an article published in 2017, with some genera including Anogeissus embedded into Terminalia.[8]

Description

In China, trees grow to 20 m tall, with a trunk to 1 m d.b.h.; elsewhere (Myanmar) they may be larger: up to 30 m tall and up to 2.4 or even 2.7 m girth, with a straight and cylindrical trunk.[9] Branchlets slightly pendent, slender, together with petioles and leaf blades golden villous when young. Petioles are cylindrical, 2–6 mm; leaf blades are lanceolate to narrowly so, 40-80 × 10–30 mm, abaxially grey-green and pilose mostly in axils of lateral veins, adaxially green and glabrous to glabrescent, base narrowed or obtuse, apex acuminate; lateral veins in 5-7 pairs, inconspicuous.

Flowers are numerous sessile on flower heads 9–13 mm in diameter; bracts are easily deciduous and linear, 4–5 mm long. Calyx tubes are approximately 5 mm long, abaxially yellow pubescent, densely so on ovary and tubular part, more sparsely so on cup-shaped part. Filaments 3–4 mm. Fruits are approximately 6 × 5 mm including a 'beak', ferruginous pubescent distally and on beak. Flowering is from February–March in Bangladesh and Thailand.
