Commelina communis is
an annual herb commonly seen on roadsides or in 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. Of the
three petals, two are significant: conspicuous, vivid blue, and the
other is white and small. Bloom time: June-September. |
