Crepidiastrum lanceolatum var. lanceolatum("Hosobawadan")
Japanese name: ホソバワダン Scientific name:Crepidiastrum lanceolatum var. lanceolatum
[Overview]
A subshrub or perennial 10–30 cm tall, found on rocky shores and similar places.
White sap comes out when the stem or leaves are damaged.
It produces lateral branches, whose lower parts creep along the ground and whose upper parts rise upright.
The leaves are of two kinds: basal leaves and stem leaves.
The basal leaves are spoon-shaped or linear-oblong, 5–15 cm long.
The stem leaves are alternate and oblong.
The leaves are either entire or pinnately divided.
On leaves on the lower part of the stem, the base clasps the stem.
Many flower heads are borne in corymbs at the tips of the lateral branches.
The heads are yellow and made up of 8–12 florets.
The fruit is an achene 2.5–4 mm long with a white pappus.
