Hypericum gramineum G.Forst.

Perennial or annual herb (0.025-)0.05-0.72 m tall, erect or decumbent but not rooting, branching strictly from the base or unbranched, occasionally with strict or ascending lateral branches, sometimes naked below. Stems green, persistently 4-lined, ancipitous when young, cortex persistent or rarely deciduous in strips; internodes 3-33(-55) mm long, those in the upper 1/3- 2/5 exceeding the leaves. Leaves sessile, spreading to appressed, 4-25 x 1.2-8 mm, lanceolate to linear or oblong or rarely ovate-lanceolate, margin plane or recurved, paler and glaucous beneath, chartaceous; apex obtuse to rounded, base cordate to rounded or sometimes cuneate, amplexicaul and usually somewhat decurrent, then forming shallow V, free; basal veins 1-3, midrib sometimes with up to 5 obscure branches, tertiary reticulum not evident; laminar glands small and dense above, larger and laxer beneath, not prominent. Inflorescence (l-2)3-c.30-flowered, dichasial/ monochasial or pseudo-dichotomous or mixed, without accessory branches, sometimes with lateral branches from up to 3 nodes below, the whole laxly obconic to narrowly ellipsoid; primary pedicels 2-17 mm long; bracts and bracteoles triangular-lanceolate to linear. Flowers 5-12(-15) mm in diam., stellate; buds ellipsoid, subacute. Sepals 2.8-7.5(-9) x 0.8-2 mm, subequal to unequal, imbricate, lanceolate to narrowly elliptic or oblong-elliptic, acute to subacute (or rarely rounded - hybrids?); veins 3-5, only midrib sometimes prominent; glands linear, distally punctiform. Petals pale to bright yellow or orange, 5-10 x 2-5 mm, c. 1-3 x sepals, obovate to oblanceolate; apiculus obtuse to rounded; glands few, striiform, or absent. Stamens c. 20-50, irregular, longest 2.5-4 mm long, 0.4-0.6 x petals. Ovary 1.5-2.3 x 0.6-1.2 mm, narrowly ovoid-conic; styles 3, 0.7-1.8 mm, long, 0.5- 0.9 x ovary, spreading; stigmas broadly to narrowly clavate. Capsule 2.5-8 x l-3.5(-4) mm, narrowly ovoid to cylindric, 0.8-1.2 x sepals. Seeds 0.5 mm long, not carinate; testa finely ribbed-scalariform.
