Agoserisとは 意味・読み方・使い方

Agoseris is a small genus of liguliferous herbs in the Asteraceae or sunflower family. In general appearance they are reminiscent of dandelions and are sometimes called mountain dandelion or false dandelion. Like dandelions the plants are (mostly) stemless, the leaves being all basal and forming a rosette, contain milky sap, produce several unbranched, stem-like flower stalks (peduncles), each flower stalk bearing a single, erect flower head that contains several yellow florets, the flower head maturing into a ball-like seed head of beaked achenes, each achene with a pappus of numerous, white bristles.
