Otanthera; Bush Strawberries
Usually flowers and fruits as a shrub about 1-2 m tall.
Leaf blades about 6.5-13 x 2.5-4.5 cm. Petiole grooved on the upper surface. Both the upper and lower surfaces of the leaf blade clothed in simple, +/- prostrate hairs. Each leaf with a midrib and two major longitudinal veins plus two other longitudinal veins which could nearly be regarded as intramarginal veins. All major veins depressed on the upper surface. Twigs +/- 4-angled in transverse section. Large hairs on the twigs between the petiole bases resemble stipules.
Hypanthium about 5-6 x 4-5 mm, clothed in persistent hairs which are arranged in clumps of about 2-3 hairs. Calyx lobes about 3-4 x 0.5 mm. Stamens ten, +/- uniform, each with a yellow gland at the base of the anther. Anthers linear, about 2-3 mm long, opening by a terminal pore. Ovary densely pubescent at the apex.
Cotyledons small, +/- orbicular, about 1-1.5 mm diam., petioles rather wide. Stem 4-angled above the cotyledons. First pair of leaves opposite and hairy. At the tenth leaf stage: leaf blade with a midrib and two major longitudinal veins plus two other longitudinal veins which could nearly be regarded as intramarginal veins. Upper and lower leaf surfaces clothed in pale prostrate hairs. Stipules (or stipule-like structures) filiform, about 3 mm long. Stem hairy. Seed germination time 24 to 83 days.
