Sabal causiarum or something else?

[Will]

I got some seeds recently which were labeled as Sabal causiarum. I showed a friend some pics of my seedlings and he said his Causiarum seeds where the size of Mexicana seeds. Now I am not sure who has the real Causiarum seeds.

Can somebody tell from these pics if the seed size fits to causiarum?

Sabal causiarum seeds are roughly the size of palmetto or miamiensis while mexicana are much larger and closer in size to domingensis.  According to Palmpedia "4.3-5.7 mm high for S. causiarum and 6.5-9.7mm in diameter" and "8.0-10.4 mm in diameter, 5.1-7.1 mm high for S. domingensis."  Yours look like they could be causiarum and your friend probably has mexicana or domingensis.  Sorry for the poor quality in the photo below but you can easily see the difference between miamiensis and mexicana and almost no difference between domingensis and mexicana.  Photo at the bottom shows mexicana seeds at the top with palmetto seeds at the bottom.

Thank you very much! I am relieved, thought I had the wrong seeds.

Any idea what those huge Sabal seeds are? On the right probably palmetto. I collected them thinking they were livistona seeds
