Morphology General Habit
Perennial herb with annual stems from a woody rootstock.
Morphology Stem
Stems climbing, trailing or suberect, up to 45 cm long, sulcate and angular (in dried state at least), sparsely to densely pubescent, often with both long and minute hairs, or tomentose.
Morphology Leaves
Leaves 2–14 ? 0.4–3(4.5) cm, linear-lanceolate to narrowly oblong-lanceolate or ovate-lanceolate, obtuse to acute, sometimes mucronate at the apex, cuneate to rounded at the base; lamina with 3 ± parallel, longitudinal veins from the base, tomentose, or pubescent with very short hairs on the lamina and long hairs mainly concentrated along the veins particularly on the leaf lower surface, or less often the pubescence of long hairs only; venation prominent below; petioles 1.5–7 mm long, tomentose, or pubescent with a mixture of long and very short hairs.
Morphology Reproductive morphology Flowers
Flowers solitary, axillary, pendulous; pedicels (including ovary) 0.3–20 mm long, pubescence as for stems; inflorescence bract 2.5–12 ? 1–3 mm, lanceolate to narrowly ovate, tomentose to pubescent with long and very short hairs.
Morphology Reproductive morphology Flowers Perianth
Perianth greenish or purplish-green in the lower part, glabrous to densely hairy; constricted part below the utricle 0.5–4 mm long; inflated part (utricle) 3–6 mm in diameter, subglobose; tube 3–15 ? 1–2 mm, straight, cylindrical, dilated at apex; limb 8–35 ? 3.5–11 mm, oblong-elliptic, rounded to subacute at the apex, glabrous to densely hairy outside, glabrous to glabrescent inside, reddish-purple to dark purplish-brown, buff-cream in throat.
Morphology Reproductive morphology Flowers Gynostemium
Gynostemium 2–3 mm tall, anthers 6.
Morphology Reproductive morphology Fruits
Fruit a pendulous6-ribbed capsule, pubescent to glabrescent, 1.5–3 ? 0.7–1.6 cm, oblong-obpyriform; apex rounded; base attenuate into stipe 7–15 mm long; the mature capsule and stipe split longitudinally into 6 segments which remain joined to the pedicel by the elements of the stipe.
Morphology Reproductive morphology Seeds
Seeds 3.5–7 ? 3–6.5 mm, triangular with rounded corners and curled margins (in dried state at least), creamy-yellow, smooth, with thick cuneate raphe down middle of one side, sometimes ± equalling the seed in width.
