Adenanthos cygnorum chamaephyton

Description

Common woollybush grows as a tall shrub up to three metres high. It has soft grey-green or grey-blue foliage, consisting of closely packed, small, hairy leaves on pliable, hairy stems. It is woolly both in appearance and feel, hence the common name. The leaves have nectaries at the tips; these attract ants, which play a role in distribution of seed. The nectar filled cups are taken by the ants to their nests to be consumed, the seeds becoming inaccessible to birds, etc. Like most other Adenanthos species, but unusually for Proteaceae, the flowers of common woollybush are not large and showy, but are rather small, dull, and hidden within the foliage. The stems of the plant are bored into by moths, leaving their eggs there; the larvae are in turn used by female wasps for their own eggs. species of Adenanthos, a genus that is mostly restricted to the Southwest botanical province. Adenanthos cygnorum was first collected by the English botanist and plant-collector Allan Cunningham in 1818 at the Swan River, Western Australia. The specific name cygnorum, from the Latin cygnus meaning swan, refers to the type locality. There are two subspecies: Adenanthos cygnorum subsp. cygnorum and Adenanthos cygnorum subsp. chamaephyton. The latter is a prostrate, mat-forming shrub; it is rare and poorly known, and some populations are under threat, but is not currently considered endangered.
