Characteristics

Shrub or tree to 20 m, 50 cm ø. Young twigs pulverulent-puberulous or rarely tomentellous, glabrescent, often dark-brown to blackish. Innovations light redbrown. Leaves chartaceous to coriaceous, often dark brown when dry, pulverulent beneath or on both faces, soon glabrescent, elliptic, acuminate, with cuneate base and recurved to revolute margin with many pellucid glands, 4½-16 by l¼-4¾ cm; nerves 4-12 pairs, meeting in a looped intramarginal vein; petiole 6-12 mm. Flowers in a spike, raceme or panicle to 6 cm; indument of axis as twigs. Bracts and bracteoles with same indument persistent in fruit, ½-1 mm. Pedicel mostly only under older flowers, to 3 mm. Calyx nearly entirely divided into ½-l mm long lobes. Corolla 2-5 mm. Stamens (20-)25-50. Disk gla-brous or rarely hairy. Ovary with same indument as that of twigs, 1-2 mm high; style glabrous or with some hairs towards the base, 2-4 mm. Fruit ellip-soid to cylindrical, sometimes with c. 6 ridges when dry, blue or black-purple, soon glabrescent, crowned by the incurved calyx lobes, with only one developed cell, 8-10(-ll) by 3-5(-6) mm. Seed 1, with straight embryo.
More
Trees 4--10 m tall. Young branchlets, buds, inflorescences, bracts, and calyces reddish brown powdery puberulent. Branchlets reddish brown. Petiole 5--10 mm, margin glandular punctate; leaf blade narrowly elliptic, elliptic, or narrowly ovate, 6--11 X 1.8--3 cm, thickly papery, powdery but soon glabrescent, base cuneate, margin subentire to sinuous-dentate and with elliptic punctate glands, apex caudate-acuminate, lateral veins 4--12 pairs. Racemes or spikes, 2--6 cm, 1--3-branched, axis tomentellous-puberulent when young; bracts and bractlets persistent, triangular-ovate, 1--1.5 mm. Ovary 1--2 mm. Calyx 0.5--1 mm; lobes semi-orbicular, 0.3--0.5 mm. Corolla ca. 3 mm. Stamens 30--35. Disc annular, glabrous. Drupes ellipsoid-cylindric, 6--12 X 3--5 mm. Fl. and fr. Jul-Aug.

Environment

Usually in montane rainforest, in moun-tain heaths, on ridge-crests and ridges, and mossy forest, also in Baeckea-Leptospermum heath forest, often on granite, but also on ultra-basic (Trusmadi), from sea-level to 3000 m, but at low altitude largely on podsolized sand (Banka; Bako N. P.) and in heath forest on humid podsol Fl. Sept. (Febr.-Oct.); fr. May (Jan.-Dec).As is the case with more species, dwarfed speci-mens or hardly 1 m high may already come into flower.
More
Kerangas forest on coastal and lowland sites; more commonly in montane forest or high kerangas forest; especially on hillsides, exposed ridges and summits, preferring poor, sandy soils, occ. on limestone and ultrabasic soils; elevations to 3,000 m.

Usage

Uses. The timber can be used for light ( DESCH Mal. For. Rec. 152 1954 593 ). Kayu kain is a vernacular name alluding to the use for tanning cloth in dyeing (see below).The Besisi (Mal. Pen.) believe that the leaves of certain plants, e.g. S. adenophylla, if carried in the quiver with their darts, act as charms bringing them success in hunting ( BURK. Dict. 1935 ).
