arrowroot
Maranta arundinacea L.
Arrowroot’s familiar name belongs to a plant with an underground storehouse: fleshy rhizomes rich in starch. Singapore’s National Parks account describes these as cylindrical and usually whitish. They are processed into flour, while the upright leafy growth makes the species useful as an ornamental as well as a crop. NParks Flora & Fauna Web: Maranta arundinacea

Recognizing the plant
The slender stems often branch near their tops.

Small white flowers occur in pairs beneath green bracts. Their corolla tubes curve and swell at the base. The small ellipsoid capsules are green or reddish-brown, enclosing brown, wrinkled seeds with a white appendage at one end. Flora of China, volume24 p.382: Maranta arundinacea
