Inflorescence 1-flowered, with flowering shoots in uppermost axil(s); pedicels usually exceeding uppermost leaves, (2-)5-17 mm in fruit. Flowers c. 7-10 mm ø, plane; buds narrowly ovoid, obtuse. Sepals 2½-5 by 0.6-1.4 mm, free, ± broadly or not imbricate, elliptic-oblong to linear, rounded to subacute or apiculate; margin entire to irregularly glandular-ciliate; laminar glands pale, punctate to shortly striate; submarginal to marginal glands black. Petals yellow, 3-7 by 2-2½ mm, oblong-oblanceolate, persistent; apiculus small, glandular or glandular-ciliate; margin entire or with few subsessile glands; laminar glands absent or few near apex, pale or black, punctate; marginal glands black.
