Hypericum fasciculatum Lam.

Shrub to 1 .5(-3) m tall, erect, much branched above but not tree-like, with branches erect or narrowly ascending. Stems orange-brown, 6-lined and strongly ancipitous when young, soon narrowly 2-winged, eventually terete; cortex exfoliating in thin papery sheets or plates exposing red bark beneath; bark either corky or spongy with inconspicuous laticifers, thick. Leaves dark green (cf. H. chapmanii), sessile, (8-)10-17(-20) x 0.7-1 mm, with those in axils as long, linear-subulate, sometimes slightly broadened distally, with margin revolute, overarching all but the raised midrib area beneath and forming 2 longitudinal grooves lined with papillae, chartaceous to subcoriaceous, deciduous at basal articulation, apex rounded-apiculate to acute, base parallel; midrib unbranched; laminar glands dense, in 2 often uneven rows beneath and scattered above. Inflorescence (3-)7-32-flowered, without accessory flowers, sometimes with single flowers or 3-5-flowered dichasia from up to 3 nodes below, the main inflorescence sometimes reverting to vegetative growth before producing more flowers, the whole rounded-pyramidal to corymbiform; pedicels absent or almost so; bracts foliar. Flowers 13-16 mm in diam.; buds ovoid, acute. Sepals 5, (3)4.5-8(- 10) x 0.5 mm, unequal, linear-subulate, acute, with margin revolute, 1 -veined, midrib unbranched, eventually deciduous. Petals 5, bright yellow, 6-9 x 4-5 mm, c. 1.2 x sepals, obovate-spathulate, with apiculus lateral, acute. Stamens c. 70-100, longest 5-6.5 mm, 0.7-0.85 x petals. Ovary 3-merous, 2.5-3 x 1-1.5 mm, very narrowly pyramidal-ovoid, acute, placentation parietal; styles 3, 2.5-3 mm long, equalling ovary, separating in fruit. Capsule 5.5 x 2.5-3 mm, ovoid-conic to ovoid-ellipsoid, 3-sulcate. Seeds dull brown, c. 0.4 mm long, ecarinate; testa finely foveolate-reticulate.
