Leaf apex and base are very confusing to me, and to FoC & FoP too! A description of leaf apex of Achyranthes aspera L., Sp. Pl. 204. 1753, var. aspera -
An illustration in FoP tells me that my earlier upload (20th July, 2012) is Achyranthes aspera L., Sp. Pl. 204. 1753, var. aspera. ... has a pic of Achyranthes aspera L. var. porphyristachya (Wall. ex Moq.)

Towns. -
So. i am not sure of the ID of this A. aspera. "Plant Groups" mentions this species as APANG in Bengali and APAMARGA in Sanskrit. Today (13/10/12) i found another plant which i think is the same species. This one is not less than four feet high and may be called a sub shrub. Attaching new pictures. Yes. seems Aapaang likes to grow in the disturbed rocky/broken bricks kinda soil!!1
I noticed a few more of this plant around my PARA. The plants here are not as big and sturdy as the third set of photographs in this post or thread. But, neither they are as small as what we usually see on roadside and waste place. I think -
This plant usually grows in shady area, under trees and shrubbery. It can attain a height of 5 ft. The leaves at base are much larger than the leaves in the middle or top of branches. This is rather an undershrub. Spikes are usually about 2 ft. or more. This plant seems to be the Achyranthes aspera var. porphyristachya of the "Flora of British India". 08feb13_DSCN6688.jpg is Achyranthus aspera Amaranthaceae Yes, it is Achyranthus aspera, more correctly Achyranthes aspera var. porphyristachya (Wall. ex Moq.) Hook. f.
Yes ... Very good photographs. Nice pictures. Likely to be Achyranthes aspera var. porphyristachya I am confused between A. aspera & A. bidentata, even after reading the keys in - https://groups.google.com/forum/?hl=en&fromgroups=#!topic/indiantreepix/nOjHm41v4wI. But, since the spikes in this thread is relatively longer and it has already been identified as A. aspera, I agree with ...

Elevation range for aspera? for this amaranth member FoP says its supposed to be densely hairy\ http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=100227 Eflora of Nepal mostly refers to eflora of China. FOC has A.aspera var. indica and var. aspera as distinct varieties ....eflora of Nepal treats them as synonyms. A. aspera var. porphyristachya is a variety mentioned in eflora of Nepal, without description, is absent from FOC . The plant list considers var. porphyristachya an accepted name along with six others as lower taxa. I already checked all and could not decide. Does it matches with Achyranthes coynei - Coyne's Chaff Flower - Flowers of Indiawww.flowersofindia.net › catalog › slides › Coyne's Chaff Flower which is not listed in Nepal ? Ok, I will check. but not before Monday Somewhere I read elevation up to 1200 meters. https://www.researchgate.net/publication/278301813_Achyranthes_coynei_Santapau_Amaranthaceae_An_Endemic_and_Threatened_Species_from_Kachchh_Desert_India May not be coynei ...! In efloraofindia it has been said that A .conyei is big brother of A.aspera, up to 3.5 meters tall sometimes. Average A. aspera height in my area is about 125 cm, spike about 50 cm. Taller plants I have seen upto 250 cm with spike longer than 100 cm, thicker, each fruit a bit bigger. Typically, they live longer. Leaf is very little hairy, larger and papery (chartaceous). Dash of red everywhere including spike . I was told it was A. aspera var. porphyristachya. I have tried to sort them out ... varieties in A .aspera in my area. Problem is, characters overlap a lot across the plants and they change with time. The look of plant changes according to season too. It will not be same in August and september and October and November. In summers, few plants will survive ...robust, tall, reddish, longer spikes, less hairy. But to say the taller ones are or are not A .conyei is impossible for me. Photographs in the paper I quoted are not really giving out diagnostic point(s) except light pink tepals ...the kind of color I have not yet seen in Achyranthes.
