Japanese name: ウメハタザオ(梅旗竿) Scientific name:Arabis serrata var. japonica f. grandiflora
[Overview]
A perennial 10–20 cm tall, found on rocky ground and gravelly sites in alpine areas other than Mount Fuji.
Stellate hairs grow on the stems and leaves.
There are two kinds of leaves: basal leaves and stem leaves.
The basal leaves are narrowly obovate, with the base narrowing abruptly.
The stem leaves are simple and alternate, elliptic to ovate-elliptic, and clasp the stem at the base, but the auricles are not very conspicuous.
The leaf margins usually have low teeth, though the degree of toothing varies.
A raceme at the stem tip bears white four-petaled flowers.
The petals are large, 1–1.2 cm long, and rounded.
The fruit is a long linear silique, borne spreading in an arch.
