Bedfordia is a genus of flowering plants belonging to the family Asteraceae. The genus includes 3 species, all endemic to Australia.
[edit] Description
Bedfordia are shrubs or small trees.
- Stems and leaves
- The young branches and lower surface of leaves and the whorl that surrounds the flower heads are densely covered with short matted and stellate hairs.[2]
- Leaves grow first on one side and then on the other in two ranks along the branches; not paired. Leaf edges are entire or with irregular rounded scallops, and have leaf stalks.[2]
- Flowers
- Heads in dense axillary branched cluster which is shorter than the leaves. Flower heads have a flat circular shape; and are surrounded by a hairy bract which is at base. Tubular, bisexual florets, scarcely longer than the bract.[2]
- Fruits and reproduction
- Cylindrical, grooved and not hairy achenes. Pappus bristles are finely toothed and twice as long as achenes.[2] B. salicina intergrades with B. arborescens (a tree) and B. linearis (a shrub).
[edit] Taxonomy
The genus was first formally described by Swiss botanist Augustin Pyramus de Candolle in the second volume of Archives de Botanique in 1833.[3] The genus name honours John Russell, 6th Duke of Bedford.[4]
