Nice pictures of Achyranthes aspera.


I have an earlier post of Achyranthes aspera L. at – https://groups.google.com/d/topic/indiantreepix/5Lmu-wGQCSI/discussion
The leaves of this species differ from those in the above post. Maybe different variety.

your pic 2 is typical infloresence 11oct12_grlgch_DSCN3885.jpg of APAAMARG of Ayurveda.
and … has explaind the varietal differences…


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
  1. in FoC = apex obtuse or mucronate
  2. in FoP = obtuse or abruptly apiculate at the apex
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.) Hook. f. in flickr. – http://www.flickr.com/photos/dinesh_valke/2897903559/
The leaves of my species seem to be different from the above. But at the same time my picture (11oct12_grlgch_DSCN3898.jpg) tells me that my species has decussate leaves, and may be with cuneate base.
Now, remains Achyranthes aspera L. var. pubescens (Miq.) Towns. –
  1. a herbarium = http://florida.plantatlas.usf.edu/SpecimenDetails.aspx?PlantID=1611
  2. attaching more images taken today. Middle spike is much longer than 10 cm. I scaled two leaves of the plant, one at base and the other at middle of the stem. Leaves at the base region are much bigger than the keys you have provided in this thread.
  3. Moreover, this plant comes from Gangetic plain, not from forests at high elevations.
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

Thank you … for the info on habitat of this plant.

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 –
  1. This variety does not form community, rather they are scattered here and there. More of an under-shrub than a herb.
  2. They may grow big, like a shrub, if left undisturbed. Regular removal of roadside weeds and collection of fuel wood by not so privileged villagers bar them to grow more.
  3. Unequal tepals, as can be seen in newly attached two pictures with this mail, suggests that it may be Achyranthes aspera L. var. porphyristachya (Wall. ex Moq.) Hook. f., conforming to the keys provided by …



Chenopodiaceae and Amaranthaceae Week : sk-19 : Achyranthes aspera var. porphyristachya (Wall. ex Moq.) Hook. f. ?:  

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 …

I feel more closer to images at Achyranthes aspera var. porphyristachya (Wall. ex Moq.) Hook.f.  rather than those at Achyranthes bidentata Blume

Achyranthes aspera. Varieties determination difficult. 

There are 4 to 5 varieties described, no key I could find online ! 


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.  


which is not listed in Nepal ?


Ok, I will check. but not before Monday


Somewhere I read elevation up to 1200 meters. 

I shall stick to A. aspera


Achyranthes


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.
