Members,

This is another amaranth i came across which is also consumed as a vegetable alike A. viridis. Could you please identify the species?

Best wishes,
Nanu

I think this represents Amaranthus cruentus L.

Queries from another thread:
"Dear members,
For the red amaranth pics i posted within the group, i received two identifications:- One A. cruentus and other saying it to be A. tricolor. Please can some help distinguish between the two. Is it true that A. tricor is not the edible species and is ornamental while A. cruentus is used for cooking...?? Not sure. And any difference in the inflorescence heads- one erect n in other species drooping?
Thanks.
Best wishes,
Nanu"

Nanu ji
Amaranthus tricolor is now correct name for what we earlier knew as Amaranthus gangeticus. A. cruentus is now correctly known as A. hybridus subsp. cruentus. The two species are distinguished as under:

Terminal inflorescence alone usually spiciform, the axillary inflorescences ± rounded clusters-or if axillary spikes present, these with globose clusters at junction with stem; bracteoles terminating in awns which are fine, flexuose and hair-like above; perianth segments 3........................................................................ Amaranthus tricolor

Terminal and at least some (generally most) of the upper axillary inflorescences spiciform, without dense globose clusters at the junction of peduncle and stem; bracteoles terminating in stout, rigid awns; perianth segments usually 5.............. A. hybridus


Subsp. cruentus has shorter bracteoles of female flower (longest mostly 1-1.5 times as long as the perianth; 1.5-2 times in subsp. hybridus), Stigma-bases and upper part of lid of fruit scarcely swollen (swollen in subsp hybridus) , fruit with no distinct “neck” (distinct neck in subsp. hybridus).
