Amaranthus species from the garden by the river

Chenopodiaceae and Amaranthaceae Week:: UD 008:: Amaranth family 5 to ID: This is one more amaranth from the garden by the river, this has green flower spike… Leaf size you can perhaps guess is about 4 inches long,  the plants were just as tall as the ones with the red spikes in the earlier submission. Very nice pictures indeed. First time observing a close up of Amaranth flowers the features of which are necessary to reach upto species level. I can't count the number of tepals and stamens ...hopefully they are 5 each. The leaf axil I think is without spines which rules out A. spinosus. I can see the Bracts/bracteoles spinous tipped (a key character.) and it is as long as or slightly longer than tepals. They may be ovate acuminate which indicates it might be A.cruentus. Thanks Satish, I need to pay more attention to smaller details when encountering these small spikes... and thanks for the details. I have this one of the area where a leaf arose and a few flowers bunched up, will this add any thing to your analysis?
