Dear Sir,

Thank you very much for your answer, and Thanks for the link of the article.

My question remains always posed !, under the same environmental conditions we notice the varietal diversity of the same species. For example: we found 14 well-distinguished forms of the seeds of the argan tree, and still morphometric criteria bear a scondary connection between the main forms, which is totally in the wild state.

For this, I have a database of measured values needs an interpretation.

With all my greetings.

I would refer to them as morphotypes. It is not unusual to find different morphs within seeds of the same species - what is interesting is why? When you say different forms, are you refering to size, shape?  

Dear Hazel and Dennis,

thank you very much for your answer,

enclosed two graphs of our study on the morphometry of the seeds of argan tree,

I would have liked your collaboration for this work,

Best regards
