Monocots abound. They may be only a quarter of all flowering species of plants, but that’s still a huge number of species. The striking blue petals of this dayflower (Commelina clavata, Jalpipari, of the family Commelinaceae) was actually what attracted my attention when I ambled past the rice fields outside the village of Pargaon. not far from the Pimpalgaon Joge Dam in Pune district of Maharashtra. The centimeter sized flowers were trimerous: three petals, three stamens with yellow anthers, and three stamenoids (false stamens). The pistil was below the anthers. The leaves were smooth and lance shaped,
PoWO lists the range to be in Sri Lanka and India, stopping west of Assam, then jumping to Myanmar, skipping Thailand to appear in Malayasia and then on the islands of Java and Sumatra. These geographical gaps must arise because of inadequate reporting. I’m pretty sure that this plant grows on the berms of rice fields in Bangladesh, Assam, other states of the north-eastern India, as well as in Thailand. Many of the dayflowers have edible leaves, and I read reports that the leaves of Jalpipari are eaten in southern Africa (where it must also grow). I wish I knew that. I would have tried to get a few of these plants home to grow in our balcony herb garden.
This note is added later in the day. I took a look at photos that I took during a walk in Nameri national park on 5 November, 2015, and came across this photo. It is clearly a photo of Commelina clavata in flower. Nameri in in Assam, and rather far east of the West Bengal border, being right at the border with Arunachal Pradesh. The national park is part of a larger protected ecosphere as the Pakke Wildlife Sanctuary of Arunachal. This observation therefore extends the range of C. clavata almost all the way to the eastern border of India. It may be just a matter of time before the gaps in PoWO’s range map are filled in.
