Hypericum aciculare Kunth

Shrub 0.3-2 m tall, erect and bushy to decumbent and slender, with branches strict to ascending, lateral and frequently pseudo-dichotomous. Stems orange-brown, 4-lined and ± ancipitous when young, eventually terete, cortex exfoliating irregularly; internodes 1-7 mm long. Leaves sessile, subimbricate or not, suberect, outcurving and usually twisting, not or scarcely tetrastichous, deciduous above base without fading; lamina 3.5-7 x 0.4-0.6 mm, very narrowly elliptic to hnear-acicular, incurved, slightly cucullate, midrib impressed beneath, margin very narrowly hyaline, concolorous, not glaucous, subcoriaceous to chartaceous; apex acute, base parallel-sided, not sheathing, scarcely broadening but pairs forming narrow interfoliar ridge; basal vein 1, unbranched; laminar glands dense to very sparse, visible beneath. Inflorescence 1-flowered, terminal, with pseudo-dichotomous branches from node below and terminating short unbranched lateral shoots; pedicel 1.5-2.5 mm long, not incrassate upwards; upper leaves not transitional. Flowers 10-17 mm in diam., stellate. Sepals 4-7.5 x 0.7-1.5 mm, narrowly lanceolate, acute, incurved above, margin hyaline, veins (3)5, midrib not prominent but whole sepal often becoming ribbed; glands linear, distally punctiform. Petals yellow or apricot to orange, sometimes tinged red, 6-10 x 3-7 mm, c. 1.5 x sepals, oblong-obovate, apiculus sharply acute; glands striiform to punctiform. Stamens 30-55, longest 3-5 mm long, c. 0.5 x petals. Ovary 1.5-2.5 x 1-1.5 mm, ellipsoid-subglobose; styles 3, 2.5-3(4) mm long, 1.2-2 x ovary, outcurving-ascending; stigmas narrow. Capsule 3.5-4 x 2.5-3.5 mm, broadly ellipsoid, shorter than sepals. Seeds 1.2 mm long, ecarinate; testa finely scalariform.
