Haec species a congeneris caulibus petiolis et folii rhachide aureo-strigulosis deinde glabrescentibus atque foliolis in sicco complanatis marginibus revolutis apice obtusis usque breviter acuminatis distinguitur.

Tree 4-25 m tall; stems densely golden strigulose, glabrescent. Petioles 2.3-6 cm, sparsely golden strigulose, glabrescent. Leaves with 3-11 subopposite to alternate leaflets; rachis 1-14.2 cm, not keeled, sparsely golden strigulose, glabrescent; petiolule 1-3 mm, sparsely golden strigulose; lea flet blade 3.2-9.5 × 0.9-4.1 cm, elliptic, coriaceous, flat in pressed material, glabrous and glossy above, glabrous to sparsely strigulose near midvein below, dull, base asymmetrical, cuneate to attenuate and decurrent along petiolule, margins revolute, apex obtuse to acute to short acuminate, midvein slightly raised above, glabrous, raised below, sparsely strigulose, secondary veins 8-14 per side, slightly raised above, flat and indistinct or slightly raised below, tertiary venation slightly raised above and below. Inflorescence axis 3.5-12.8 cm long, 1.1-1.8 mm in diam., unbranched, densely golden hirtellous; bracts 0.6- 0.8 mm, narrowly triangular, cucullate; pedicels usually paired on a common peduncle c. 0.5 mm, sometimes solitary and epedunculate, 2-3.8 mm, c. 0.3 mm in diam., sparsely golden hirtellous. Male flowers with a cupulate, 5- to 7-lobed calyx, the lobes 0.5-0.8 × 0.3-0.8 mm, triangular, sparsely puberulous outside and inside; disc 1.5-1.8 mm in diam., granularfarinose; stamens 5-7, filaments 3.6-7.0 mm, glabrous, anthers 0.7-1.0 × 0.4-0.6, ellipsoid; pistillode 0.2-0.5 mm high, conical, hirtellous. Female flowers with a cupulate, 6-lobed calyx, the lobes c. 0.5 × 0.4 mm, triangular, sparsely puberulous outside, reflexed with the apex incurved; disc 1.7 mm in diam., convex, granular-farinose; staminodes 7-8, antherodes ellipsoid; ovary 1.7-1.8 × 1.6-1.8 mm, globose, sparsely strigulose, style 2-1-2.4 mm. Infructescence 7.5-15.2 cm, 1.1-2 mm in diam.; pedicels 3-5 mm in fruit. Fruit spheroid to less often ellipsoid, 14-19 mm high, 10-17 mm in diam., apiculate, the apiculum 0.3-0.6 mm, glabrous; fruit wall 0.7-1.1 mm thick; seed discoid, 10-12 mm in diam., 6-7 mm thick.

Etymology. – The epithet vulgaris refers to the common, widespread occurrence of the species.

Vernacular names. – “Borasaka”, “Lanary Elatrangidina”, “Maintipotora”, “Marankoditra”, “Ramaindafa”, “Ramendafa”.

Conservation status. – Beguea vulgaris is widespread (Fig. 3), with an EOO of 65,664 km2 and an AOO probably greater than 2,000 km2 given the amount of potential suitable habitat within the EOO. It occurs in the protected areas of Analamazoatra, Marojejy, Masoala, Ranomafana, Tsitongambarika and Zahamena, and is known from a minimum of 16 locations with respect to the threat of forest degradation and clearing. It is therefore assigned a preliminary assessment of “Least Concern” [LC] using the IUCN Red List criteria (IUCN, 2012).

Notes. – Beguea vulgaris is widely distributed from Marojejy PN to Bemangidy near Tolagnaro (Fig. 3) in mid-elevation humid to subhumid forest. It is easily distinguished from B. apetala by its flat vs folded leaflets, with an obtuse to acute to occasionally short acuminate apex (vs a long acuminate apex), and from B. tsaratananensis by its leaflets with revolute margins and its puberulous sepals (vs flat leaflet margins and glabrous sepals) (Fig. 2 D, 12D).
