Hypericum millefolium (Nomenclature)
Shrub up to c. 2 m tall, erect, juniperoid, with branches strict, pseudo-dichotomous (extension) and shorter, lateral (flowering). Stems 4-6-lined and ancipitous when young, persistently 4-angled and ancipitous until cortex exfoliates at first in strips between subfoliar ridges, then terete, fragile, green becoming pale grey; internodes 1-2 mm long. Leaves sessile, imbricate to curved-ascending, tetrastichous, eventually deciduous with attached cortex below after (?) fading; lamina 0.7-2 x 0.8-1 mm, lanceolate-triangular, incurved, markedly cucullate, midrib impressed beneath, margin narrowly hyaline, dull above, lucent or ± glaucous beneath, coriaceous; apex acute, pungent, base broad, subamplexicaul, pairs united to form narrow interfoliar ridge; basal vein 1 , unbranched; laminar glands obscure. Inflorescence 1-flowered, terminal and on numerous short lateral branches (branching or not), occasionally with pseudo-dichotomous branches from node below; pedicel absent or up to 0.5 mm long, incrassate upwards; upper leaves not transitional. Flowers 5-7 mm in diam., obconic. Sepals 3-3.5. x 1 mm, lanceolate, acute and incurved-cucullate to pungent; veins 5, unbranched, midrib ± prominent; glands linear, uninterrupted. Petals deep? yellow, 6-7 x 2.5-3 mm, 2 x sepals, oblanceolate; apiculus very acute; glands linear, distally subpunctiform. Stamens c. 50, longest 4-5 mm long, 0.6-0.7 x petals. Ovary 1.5x1 mm, broadly ovoid; styles 3, 4-5 mm long, c. 3 x ovary, diverging-incurved; stigmas narrow. Capsule 4x2 mm, ovoid, exceeding sepals. Seeds not seen.
Among steep limestone rocks; 1750-2350 m.
Haiti (Massif de la Selle).
Hypericum millefolium, with its ericoid habit, is at first glance quite distinct from any other species in sect. Brathys. Closer investigation, however, shows it to be similar to the smaller form of H. pycnophyllum. Its triangular leaves and numerous fragile flowering stems, nevertheless, make it easily recognisable.
