Lathyrus japonicus is
a perennial herb found in sandy soil in seashores, the whole being
powdery white and stems angular. The stems crawl on the ground to
grow to about 1 m long, and the leaves are of a pinnately compound
leaf, with 6-12 leaflets, 1.5-3cm long, 1-2cm wide, and oblong.
Stipules are big, about the same size as the leaflets, and flowers
set themselves 3-6 in a racemose way. Vexilla are red-purple at
first and turn blue-purple later. White flowers can occur rarely.
Bloom time: April-July. |
