Tilingia ajanensis var. ajanensis("Shiraneninjin")
Japanese name: シラネニンジン（白根人参） Scientific name:Tilingia ajanensis var. ajanensis
[Overview]
A perennial 5–40 cm tall, found in sunny, open places in the subalpine to alpine zones, above the dwarf pine zone.
In grassland the plants grow taller, and on wind-exposed ground and rocky places they stay low.
It is hairless throughout.
The stem is erect, branched in the upper part, and ridged.
The basal leaves are 2–3 times pinnately compound, and the leaflets are further divided; the lobes vary greatly from ovate to linear, and are somewhat thick and glossy.
Stem leaves are absent or, if present, small, with 1–3 arranged alternately.
The flowers are small, white and 5-petaled, borne densely and in large numbers in compound umbels.
The calyx teeth persist.
The inflorescence has involucral bracts and involucels.
The fruit is a mericarp.
[Notes]
The Japanese name compares the leaves to carrots and derives from Mt. Nikko-Shirane, where the plant was first collected.
