Hypericum pulogense


Suffrutescent herb, 20-40 cm, branches strict, erect or ascending to decumbent from slender branching rhizome, 2(-4-6)-lined or narrowly 2-winged when young, sometimes eventually terete. Leaves sessile or very shortly petiolate, 0.8-1.2(-2) by 0.3-0.7 cm, elliptic to oblong or ovate, apex obtuse to rounded, base broadly cuneate to rounded, glaucous beneath, margin recurved (at least when dried), spreading or ascending; c. 4 main lateral veins, ± parallel, slightly branched, uniting near margin and apex, with scarcely visible reticulate venation; laminar glands pale, ± prominent, punctate and shortly striate; intramarginal glands pale or apparently absent. Inflorescence 1-flowered, with or without flowering shoots in uppermost axils, or regularly dichasial with 3-c. 10 flowers; pedicels shorter than uppermost leaves, 4-6 mm in fruit. Flowers 2-2½(-3) cm ø, plane; buds narrowly ovoid, subacute to obtuse. Sepals 4-6 by 1.8-2.4 mm, free, imbricate, lanceolate to oblong or elliptic-oblong, rounded or subapiculate, entire; laminar glands pale, linear and punctate; submarginal glands pale. Petals bright yellow, 10-12(-14) by 4-6 mm, narrowly oblong-obovate, entire to subentire, persistent; apiculus small, glandular; laminar glands pale, linear, becoming striate and punctate distally; marginal glands pale. Stamens not obviously in fascicles (or in 5 fascicles, fide MERRILL), C. 30-60, longest c. 9 mm, c.¾ as long as the petals, persistent; anthers bright yellow, gland amber. Ovary 3-4 mm, broadly to narrowly ovoid; styles 3, c. 5 mm, 1.4-2 times as long as ovary, divergent; stigmas not capitate; placentas 3, axile. Capsule 5-8 by 4-5 mm, narrowly ovoid to ovoid, longitudinally and diagonally vittate. Seeds yellow-brown to dark brown,½-1 mm, cylindric, not carinate, densely linear-scalariform.

H. pulogense is known only from Mt Pulog and Mt Tabayoc. Its nearest relatives (other than H. beccarii) are in New Guinea. The only specimen from Mt Tabayoc has slenderer, more decumbent stems than those from Mt Pulog. In these respects it approaches H. beccarii.
