Appearance
"Corethrogyne filaginifolia" is a robust perennial herb or subshrub producing a simple to multibranched stem approaching 1 metre in maximum length or height. The densely woolly leaves are several centimeters long and toothed or lobed low on the stem and smaller farther up the stem.The inflorescence is a single flower head or array of several heads at the tips of stem branches. The head is lined with narrow, pointed, purple-tipped phyllaries which curl back as the head matures. Inside are many purple, lavender, pink, or white ray florets and a center packed with up to 120 tubular yellow disc florets.
The fruit is an achene with a pappus of reddish bristles on top.
Naming
The taxonomy of this plant and certain relatives is currently changing; recently the "Corethrogynes" have been grouped together under the name "Lessingia filaginifolia", and then moved back to genus "Corethrogyne" as a single species with many synonyms.References:
