Tuberaria guttata bupleurifolia

Description

Tuberaria guttata is an annual plant that grows to 2–30 centimetres (1–12 in) tall.It has a rosette of basal leaves,each up to 3 cm (1.2 in) long and 1.5 cm (0.6 in) wide,but this rosette has normally withered by the time the plant is in flower.The stems bear 2–5 opposite pairs of leaves,and a few smaller leaves higher up,arranged alternately.The inflorescence comprises around 12 flowers,8–12 mm (0.31–0.47 in) in diameter.Each flower has five uneven sepals and five yellow petals usually with a dark red spot near the base.The flowers are cleistogamous,producing little pollen and no nectar,and attracting few insect visitors,and the petals fall off after only a few hours.The centre of the flower houses around 20 stamens and a single capitate stigma.The fruit of T.guttata is a capsule containing many seeds,each 0.6 millimetres (0.024 in) long.
