This plant grows only when the level of flowing water recedes and the flow of water becomes low but not stagnant. This is typical plant of the paddy fields, hence it is called as Bhat(rice)-Kamal in marathi. You may observe that the submerged leaves are narrow and shortly petioled and the floating leaves are with long spongy grooved petioles; their length varying as per the level of water. The spathe in which the flower grows is also with varying length of grooved tubular spongy peduncle to bring the flower just above the water.


Plant for ID SMP4 – 25/1/2011: An aquatic herb for ID. White flower of the size around 5 cm.

Though I have recorded on my camera for the first time the plant appears to be not uncommon.
It is mentioned in Srikantji’s FOS as ‘Bhat Kamal’ भात कमळ  as it is common in flooded rice fields and lakes and ponds of Konkan. Family : Hydrocharitaceae.

– Observed this abundantly growing in the wet lands and water logged areas of Bihar.

Appears like Ottelia alismoides (L.) Pers.; bad photos indeed; there are no flowers in photos and how could you guess inflorescence type ?

It is Ottelia alismoides of Hydrocharitaceae

Thanks a lot for the identification. Yes it is indeed a bad photography. I cannot see any flowers but only dissected leaves.

It is Ottelia alismoides (L.) Pers. (Hydrocharitaceae).

Your photograph is devoid of floral parts. May be it is Ottelia alismoides, a member of Alismataceae

Attaching a collage of Ottelia alismoides (DUCK-LETTUCE/ WATER PLANTAIN).

This aquatic plant is known to me from my childhood in a village (Now in Bangladesh). We used to call it KEURALI. We used to eat the fruits raw and as cooked vegetable. Today I spoke to my friend (from the same village now living in a town) about this plant. He told me he has not seen it for many years. We are making the earth poorer each year.

cant see the flower details

This species is in plenty in Surat …… commonly seen in Irrigation canals and ditches by their side, particularly near the bridges made for village/ agricultural roads ……. because that spot tends to be deeper a bit and water stagnates longer even after supply is stopped, facilitating its growth. Ottelia and Potamogeton are two common species in such water courses.

Attaching a collage of the species. The habitat is under threat. I don’t know weather I will be able to get the fruits.
