Commelina communis is
an annual herb commonly seen on roadsides or grasslands. The lower
parts of stems crawl on the ground and branch well to take roots at
nodes to propagate themselves, and the upper claims arise obliquely
upward to 30-50cm in height. Of alternate phyllotaxis, leaves are
ovate-like lanceolate, with bases becoming membranous sheaths and
embracing the stems. Flowers singly appear from inside
inflorescences enveloped in folded boat-like sheathes that
oppositely emerge against leaves and shrivel in half a day. Two of
the three petals are significant: conspicuous, vivid blue, white,
and trim. Bloom time: June-September. |
