The flowers will eventually open wide with petals more or less planar. The flowers are on longish petioles (stalks) and here form a hemishhere at the top of a stout hairy stem which is hairless (at least at the moment).

The sepals, 5 each flower, areshort and rounded - splayed out beneath each flower in such a drab colour as to be almost un-noticeable - grey-green to brownish. The petals also number 5 and are pale-pink to whitish. Surrounding the 2 central stigma are 10 filaments with small x-chromosome shaped pink anthers. When fully open the flowers will be 10-15mm across.

Similar to Rhubarb the leaves grow large and umbrella-like, hence this is also called Umbrella Plant


Not to be semantically confused with : Indian Horse-chestnut (Aesculus indica), Indian-bean-tree (Catalpa bignonioides), Indian blanket (Gaillardia pulchella), Indian Balsam (Impatiens glandulifera), Indian Pea (Lathyrus sativus), Indian Pokeweed (Phytolacca acinosa), Indian Knotgrass (Polygonum cognatum), Indian Fountain-bamboo (Yushania anceps), Brazilian Giant-Rhubarb (Gunnera manicata), Chilean Giant-Rhubarb (Gunnera tinctoria), Rhubarb (Rheum x rhabarbarum), Monk's-rhubarb (Rumex alpinus), [all plants with similar names in differing families]

Uniquely identifiable characteristics

Distinguishing Feature :

The leaves, absent on this young specimen, can be as large as Rhubarb leaves, hence the common name.

No relation to : Brazilian Giant-Rhubarb (Gunnera manicata) or Chilean Giant-Rhubarb (Gunnera tinctoria) or [plants with similar names and that look a little like Rhubarb, but which belong to the Giant-Rhubarb Family (Gunneraceae)]. Nor with Rhubarb (Rheum × rhabarbarum) [another unrelated plant with similar name]

It is an introduced and naturalised neophyte which grows in damp places, here on a river bank, usually planted or cast aside, but can naturalise. From it's common name your Author would guess it is a native of India.
