Hypericum peninsulare Eastw.

Subshrub or perennial herb 0.15-0.35 m tall, with taproot; branches lateral and below inflorescence, strict, also basal or near-basal, not rooting, erect from spreading geniculate base, often forming ring round stem base. Stems reddish, persistently 4-lined, ancipitous and densely gland-dotted when young, cortex exfoliating in strips; internodes 6-30(45) mm long. Leaves sessile, all spreading from base or upper erect, longer to shorter than internodes, persistent (i.e. deciduous with cortex) or lower breaking off earlier above base; lamina 5-23 x l-4.5(-6.5) mm, linear to narrowly elliptic or narrowly elliptic-oblong or lanceolate, margin strongly revolute, entire or subdenticulate, not cucullate, midrib prominent and smooth beneath, finely papillose or almost smooth above, glaucous beneath, subcoriaceous to chartaceous; apex acute to obtuse, base parallel-sided to cuneate or rounded-amplexicaul, free; basal veins 1(3), without or with 2-4 pairs of ascending lateral branches visible beneath, tertiary reticulation absent; laminar glands dense, often slightly prominent beneath. Inflorescence 5-9-flowered, lax (c.f. 85. eastwoodianum), branching dichasial/monochasial (after 1(2) nodes), with subsidiary branches from node below; peduncle and pedicels l.5-3(-5) mm long; bracts and bracteoles linear. Flowers 5-15 mm in diam., stellate. Sepals 3-5(-6) x 0.8-1.5 mm, subequal, narrowly oblong or narrowly elliptic-oblong to lanceolate, acute to subacute; veins 3, unbranched, all becoming prominent; glands all linear or punctiform in upper ¼ to1/3. Petals bright yellow, tinged red in bud, fading pinkish-orange, 5-7.5 x 1.5- c. 2.5 mm, 1.2-2 x sepals, oblanceolate to oblong; apiculus obtuse?; glands linear, distally interrupted. Stamens 15-22, longest 2.5-3 mm long, c. 0.5 x petals, fascicles not distinct. Ovary 1-2 x 0-5-1 mm, narrowly ovoid; styles 3, 1.5-2.5 mm long, 1.2-1.5 x ovary, spreading; stigmas broadly capitate. Capsule 4-7 x 2-3 mm, ovoid-ellipsoid to cylindric-ellipsoid or ellipsoid, terete, acute to acuminate, exceeding or rarely equalling sepals. Seeds 0.7-0.8 mm long; testa finely scalariform.
