Hypericum monadenum (Nomenclature)
Perennial herb, 0.05–0.11 m tall or long, glabrous, with stems erect to ascending from ± woody caespitose base, rooting and branching. Stems 2-lined, green, eglandular; internodes 5–15(–20) mm, shorter than to exceeding leaves. Leaves petiolate, thinly coriaceous, ± glaucous, 4–11 × 4–8 mm, broadly oblong-ovate to circular, apex rounded, margin plane to slightly indurated, base rounded, with pairs of ascending lateral veins; laminar glands pale, distal, punctiform, few or absent; intramarginal glands pale, spaced, conspicuous and one black, apical. Inflorescence 3–c. 21-flowered, from 1–2 nodes, subcorymbiform, rather dense, with lateral branches ascending; ‘cymules’ 1–5-flowered, branching monochasial, without flowering branches below; bracts and bracteoles elliptic, black-glandular-ciliate. Flowers 10–15 mm in diam., petals erect after flowering; buds cylindric-globose, rounded. Sepals subequal to equal, 2.5–5 × 1–1.5 mm, elliptic to narrowly oblong, obtuse to rounded; veins 3; margin black-glandular-denticulate. Petals bright yellow, tinged red in bud, 5–7 × 3.5 mm, 2–2.5 × sepals, oblong; marginal glands apical, few, black, on cilia; laminar glands pale, striiform. Stamens 15–23, longest 4-7 mm, 0.9–1 × petals. Ovary c. 2 × 1 mm, narrowly ovoid; styles not seen. Capsule 4–5 × c. 1.5 mm, narrowly ovoid. Seeds ‘dark-coloured’ (fide Stef., 1931), shallowly rugulose.

Hypericum monadenum, like 20. H. havvae, is apparently confined to one locality. These species have similarly-shaped leaves, but H. monadenum is smaller in all parts, and its leaves have an apical black gland that is absent in H. havvae.
Type as for H. ovalifolium Stef. (1931) non Koidz. (1918). Greuter et. al. (1986) queried the validity of Koidzumi’s name, suggesting that it was superfluous; but this is not so. Koidzumi provided a complete description of his species without reference to any previous name.
