Hello!

Unfortunately I can’t see many ID features on these seeds, could you tell me please:

– Are they hard or soft when pressed?
– Is there a hilum present?

Thank you, Jennifer

Hi Jennifer

They are hard when pressed,
There’s no hilum present, may be more like an aril.

Thanks

Hello,

These seeds are a challenge to identify without typical features! I wonder if these seeds became deformed during development?

If they are 2-3 mm long, Alternanthera tenella in the Amaranthaceae can appear similar. There are not many images available, but this page has a small one: https://grupomipdam.blogspot.com/2018/11/alternanthera-tenella-colla.html

The surface also reminds me of Plantago lanceolata in Plantaginaceae and Senna obtusifolia in the Fabaceae. These seeds might be too large, and I’m not sure what deformed seeds would look like.

I hope this helps a bit, please let us know what you find! Jennifer
