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).

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]

gollark: Nothing in the code actually uses it apart from the ECC library, but it's there.
gollark: Interesting fact: PotatOS actually ships its own secure RNG for cryptographic purposes.
gollark: It takes me something like 10 seconds to publish code I write in random-stuff and no effort to not do that.
gollark: It doesn't take much effort to do this.
gollark: Generally not for very long, at least?
