Description
Aphyllocladus species are monoecious shrubs.
Stems and leaves
The species have stems with strong and very wide ribs, with tufts of long simple, two- to three-celled, flagellate hairs in the narrow grooves between them, and large secretory cavities. The linear to spathulate leaves, are alternate set along the branches, but are shedded early so the plants look leafless most of the time.
Inflorescence
The flower heads are set individually at the tip of the branches. The lilac to purple corollas of the disc florets are deeply split, creating five coiled lobes. The anthers have stump tips, long pilose tails, and produce pollen that is higher than wide. The branches of the style are finely grainy on the outside. The one-seeded, indehiscent fruits (called cypselas) may have long-pilose hairs or lack hair altogether, but are not bristly or barbed.[5]
