Section: sect. AdenosepalumSubsection: subsect. Adenosepalum
Perennial herb 0.12-0.8 m tall, erect to ascending or occasionally decumbent but not rooting at base, with woody rootstock, few-stemmed, unbranched below inflorescence, with stems shortly whitish-crisped-pubescent to puberulous below inflorescence or rarely glabrous, leaves densely whitish-pubescent to rarely scabrellous or subglabrous on both surfaces. Stems green, terete or uppermost internodes 2-4-lined; internodes exceeding to shorter than leaves, eglandular. Leaves sessile; lamina 15-60 x 5-25 mm, ovate to oblong or lanceolate, paler beneath, thinly chartaceous, not glaucous, densely shortly pubescent or velutinous to scabrellous beneath, more shortly so above, plane, spreading; apex obtuse or rarely subacute to rounded, margin entire, base cordate-amplexicaul to rounded or rarely broadly cuneate; venation: 2-4 pairs of laterals curved-ascending from lower 0.25-0.35 of midrib, tertiary reticulation rather dense, obscure, not prominent; laminar glands all pale or usually a few black scattered distally and towards margin, dense, unequal; intramarginal glands black, dense or rather irregular. Inflorescence 5- over 150-flowered from 1-8 nodes, sometimes with flowering branches from up to 3 lower nodes, cylindric to rounded- pyramidal; pedicels 2-4 mm: bracts and bracteoles elliptic to linear-lanceolate, black-glandular-ciliate and sometimes -auriculate. Flowers 15-20 mm in diam.; buds cylindric to ellipsoid, rounded. Sepals (3-)4-7 x (0.8-)l-3 mm, unequal to equal, free or shortly united, broadly to rather narrowly oblong or elliptic to subspathulate, obtuse (or rarely subacute) to rounded, with margin long-glandular-ciliate to glandular-denticulate or very rarely entire and eglandular; veins 5, outer ones commissural; laminar glands pale only, shortly striiform to punctiform; marginal glands black, flat-topped. Petals pale yellow, rarely red-veined, 7-12 x 3-5 mm, c. 2 x petals, elliptic to oblong, rounded, apiculus absent; laminar glands pale, elongate-punctiform, scattered, or absent, rarely also a few subapical laminar and/or marginal black gland dots. Stamens c. 30-55, longest c. 4-8 mm, c. 0.65 x petals; anther gland black. Ovary 1.5-3 x 1-1.5 mm, ellipsoid; styles 2.5-5 mm, 1.5-1.65 x ovary, spreading. Capsule 4-6 x 2-4 mm, broadly ellipsoid, enclosed when developing by petals twisting together. Seeds blackish red, 0.6 mm long; testa finely scalariform.
