Oxalis dillenii,a
perennial herb originating in North America, grows wild on roadsides
or wastelands in western Japan. It resembles Oxalis corniculata.
However, all the terrestrial stems arise from rhizomes running
sideways underground and rise to 10-50cm in height. The flowers are
yellow and 5-petaled; after flowers, gynophores go downwards. The
whole is somewhat hairy, and small stipules could be more
inconspicuous. Bloom time: April-October.
