Species

Angiosperms > Malpighiales > Ochnaceae > Ochna

Characteristics

Understorey forest trees up to 6 m tall with red wood and a dark rough bark not peeling off; shrubby in open vegetation or reduced to soboliferous shrublets when exposed to fire and frost, 0.5-2 m tall. Branches and branchlets dark brown or grey, lenticellate; young twigs pale fawn coloured, the epidermis peeling off in small thin membranous white flakes. Galls often present, globose with rosulate, ovate, obtuse bracts. Leaves tardily deciduous, narrowly oblong, variable in size, 5-12(-14) cm long, 1.5-2.5 cm broad, apex and base generally obtuse, margin serrulate, rarely subentire, midrib distinct, lateral veins at right angles to midrib, leathery, shortly petiolate; stipules intrapetiolar, elongate-deltoid. Flowers fragrant, in compound, many-to few-flowered racemes or subumbellate, terminating short lateral spurs; pedicels up to 2.5 cm long, articulated in lower quarter. Sepals elliptic-convex, about 9 mm long, green, slightly larger in fruit, turning wine red. Petals broadly obovate, c. 15 mm long, clawed, yellow. Stamens c. 30, with filaments 3 mm long; anthers biporose, 2 mm long. Carpels 6-12, usually about 8, erect; styles fused, terete, the apical ends free, recurved, forming swollen irregular glandular stigmas. Drupelets oblong-globose, 10-15 mm long, attached basally black, shiny. Flowering in spring.
More
Understorey tree, 0.15-10.00 m high; wood red; bark dark, rough; branchlets grey, lenticellate, galls often present. Leaves shortly petiolate, narrowly oblong, apex and base obtuse, margins serrulate; lateral veins at right angles to midrib, leathery; stipules intrapetiolar, elongate-deltoid. Pedicels dark brown, slender, up to 25 mm in fruit, articulated in lower quarter. Sepals elliptic-convex, green at anthesis, wine red in fruit. Petals obovate, yellow, fugaceous. Stamens ± 30; filaments 3 mm long, anthers biporose. Carpels 6-12, stigmas irregular, glandular. Flowering time July-Dec. Fruit black, shiny drupelets.
Leaves petiolate; lamina 3–12 (14·8) × 1–3·5 (5) cm., elliptic or oblong to oblanceolate (rarely obovate), rounded (more rarely obtuse to acute) and occasionally apiculate at the apex, with margin serrate with curved or straight teeth or almost entire, rounded or shallowly cordate (more rarely cuneate) at the base, coriaceous, with main and subsidiary lateral nerves almost equally prominent and tertiary venation prominent above but less so or almost plane below; petiole 1–2 mm. long, slender.
Bushy shrub or small tree 0.75–4·5 m. high (to 7 m. or more in Natal), sometimes branching below ground level, evergreen or deciduous, frequently galled, with bark rather rough, brown; branches ± ascending, whitish and flattened and frequently peeling at first, becoming purplish and terete with numerous lenticels (sometimes appearing lepidote).
Flowers (2) 3–14 (c. 20), in lax or ± condensed panicles or sometimes reduced to simple racemes or pseudumbels, terminal or on short axillary shoots; pedicels (0·8) 1·2–2·5 cm. long in fruit, articulated in the lower 1/4.
Understorey forest tree or shrub, 0.5-2.0 m or up to 6 m high. Leaves shortly petiolate, leaf base obtuse. Flowers in many-to few-flowered racemes. Carpels 6-12, usually about 8. Flowers yellow.
Sepals 5–8 (11) mm. long in flower, elliptic to elliptic-oblong, rounded, becoming red, 7–12 (14) mm. long, ± convex and ± spreading in fruit.
Petals bright yellow, sometimes dark-veined, (7) 8–18 (21) × 6–12 (14) mm., obovate or obovate-oblong to suborbicular and unguiculate.
Stamens with anthers (1·75) 2–3 mm. long, 2/3–1 (1 1/3) times as long as the filaments, straight, dehiscing by apical pores.
Carpels (6) 8–13, with styles united almost to the apex with free ends spreading radially or recurved; stigmas flattened.
Drupelets subglobose or flattened-ovoid-cylindric, inserted near the base, 6–11 (12·5) × (4·5) 5–7 mm.; embryo straight.
