Rinorea anguifera


Leaves distichous (spirally arranged on terminal or crooked branches). Stipules (4-)5-9(-11) mm long, triangular, not appressed, with a distinct keel sometimes protracted into a slender tip, more or less striate, in Borneo persistent, otherwise the scars not conspicuous. Flowers with up to c. 20 in dense axillary (sub)sessile clusters on twigs and sometimes also on branchlets; Sepals c. 4-5 mm long, fleshy, hairy, the inner ones narrower than the outer and slightly exceeding them. Petals c. 5-7 mm long, strap-shaped but wider in the middle, top recurved, often the whole petal S-shaped, outside with a median band of appressed silvery hairs. Stamens with distinct fi-lamental tube, slender sometimes hairy filaments and small glabrous anthers; Ovary with its long appressed hairs obconical, ovules 6, style with patent hairs, glabrous towards the top. Fruit subtended by the persistent sepals, before dehiscence globose, hidden in a (mostly) dense, moss-recalling mass of more or less branched, hairy appendages on the valves, in all 1½-3½ cm ø. After dehiscence the seeds become visible, about 3 in number, ellipsoid, 4-7 mm long, evenly straw-coloured, glossy.

In Malesia common in the Malay Peninsula S of 7°35’ N in Thailand; throughout Sumatra where very common in the East Coast Residency; scattered in Borneo N of the Kapuas in Kalimantan and Sarawak (all divisions) to Brunei; also at 2°50’ N, 117°40’ E in NE.

A shrub 1 m to a treelet 10m tall. Bark smooth, mottled. Flowers mostly white to sometimes yellow, facing upwards from the horizontal branches, anthers light brown. Fruit greenish at maturity. KING'S collector's notes to 10084 from Perak: “in dense bamboo forest, flowers deep-red with pale reddish green, waxy tinged”, do not fit in with any other data.
In RIDLEY 4824 from Singapore, the pedicels are 3 mm.
In TEIJSMANN fl. 30.VIII.1872 from Lingga, Bt. Sipindjang off Sumatra, the branchlets are slender, somewhat crooked, the leaves almost glabrous, concolorous, and not distichous, 2-3 mm petioled, c. 4-6 by 1½-2 cm. TEIJSMANN fl. 14.IX.1872 from Lingga, Sg. Tanda, is similar but the leaves are c. 7-9 by 1½ cm. Habit unknown.
