Dichocarpum
nipponicum var. sarmentosum is a perennial by a
mountain river in damp places. Rhizomes are short and
enveloped with broad petiole bases; stems measure 5-18cm
tall and emerge 5- 7 cm long runners after flowers.
Radical leaves are 3-11cm long, including the petioles,
with broad bases, in a broad-oval shape, comprising
three leaflets with fan-shaped terminals with uneven
incisions or dentitions on the margins. And lateral
leaflets cut themselves in 3-5 newly. On-stem leaves are
on the upper half, generally of opposite phyllotaxis,
1.2-4.5cm long inclusive of the petioles in the shape of
a fan-shaped reniform or cut in three lobes anew.
Flowers have five sepals with narrow obovate, 7-9mm
long, pale yellow red-brown portions at the bases, and
petals, 5 in number, 4mm long, linear with circular
tips. Bloom time: March-May. |
