spines along te edges  are visible (in a small section of the picture only)

so its Agave

yucca is spineless

so next time pay attention to leaf thickness, end pint, and edges

Is it Agave americana?

[ushadi]

Leaf thickness and width rules it out I think, Promila

I would like to go with Agave americana L. as per comparative images at Agave‎ and keys herein.

[ushadi]

the leaf is not robust enough

look at these

http://2minutegardener.blogspot.com/2012/02/photo-century-plant-agave-americana.html

http://www.scientificlib.com/en/Biology/Plants/Magnoliophyta/AgaveAmericana01.html

the following url shows pictures with cross sections of the leaves

I call that ROBUST ... thick... leaves

https://mowryjournal.com/2013/06/18/agave-americana/

===

the presented plant is agave thin leaved

thin enough to flop over

not Agave americana

sorry to bring a negative opinion

Regards

Ushadi

Thanks, Usha ji,

There are lot of mis-identification in these species.

We have to follow keys at Agave‎

[surajitno...@gmail.com]

Please make sure Agave americana can grow wild in our country, because as per Botany of Bihar and Orissa, only Agave vera-cruz was more or less naturalized (in Singbhum). And I agree with Ushadi, americana is a roust plant.

[J.M. Garg]

Any suggestions, Surajit ji?

Sir,

I still do not know if  Agave americana has been naturalized in our country or not. Even if it is naturalized, there must have been some mother or grandmother or great grandmother plant nearby.

However, as per lucidcentral, (1), the leaves of A. americana are not flexuous, that is why they bend at the tip region only, but leaves are flexuous in A. cantula. (2) the colour of the leaves of A. americana are quite different than any other Agave species, how can I describe it .... like kind of stonewashed or stony textured.

I think, in the 2nd picture, some of the apical spine, though not clearly visible, can be called acicular.

So, I would suggest A. cantula Roxb. for this specimen. Of-course, in that case too, there must have been some mother plants somewhere nearby.

Thank you

With regards

Please, also note, leaf base in this specimen are not significantly fleshy (thick).

Thank you

I forgot to tell you that I found KEY to three Agave - https://keybase.rbg.vic.gov.au/keys/show/7710 and saved a screenshot following the steps thereon.

Thank you
