Description
Mitrasacme pygmaea is a small annual herb up to 20 cm high. Its leaves are oval to lance-shaped and slightly rough in texture. Flowers are white, trumpet-shaped, and borne on stems up to 32 mm long. They are produced in clusters at or near the ends of the branches. The fruit is a small egg-shaped capsule, 2-3 mm long.
Distribution
In NSW, M. pygmaea is known only from Mt Warning National Park.
Habitat and ecology
- Pygmy Bishop's Hat grows amongst rock outcrops in open habitats.
- Flowers and fruits February to September.
- Pygmy Bishop's Hat is an 'annual', ie each plant lives for one year and dies after flowering and fruit-set has finished.
- Because Pygmy Bishop's Hat is an annual, wide fluctuations in annual population size may occur, dependent upon such variables as rainfall, fire, seed-bank etc.
