I have seeds I lost the label for and not sure if there is any difference in the three species seeds. I am going to grow them regardless. 

They were from Montgomery Botanical Garden seed auction. I got seeds from Sabal Maritima, domingensis, and Causarium. 
 

The seeds are rather small and dark, no bigger than a Sabal Palmettos.

Maybe if I can’t identify them as seeds, Someone will know if they look different as seedlings, so I know before they are decades old!

Ryan, domingensis seeds are much larger than palmetto seeds - just slightly smaller than mexicana seeds.  Seems to me that maritima and causiarum seeds are roughly the same size as palmetto, but there might be a difference of a mm or 2.  Seed differentiation will be your best bet - I seriously doubt that you could tell them apart as strap-leafed seedlings.  Can't get into Palmpedia at the moment, but maritima seeds are typically between 8.0-10.4 mm wide and 5.1-7.1 mm high.

Got back into Palmpedia - correction to numbers given above:

"A similar size difference is found in the seeds: 8.0-10.4 mm in diameter, 5.1-7.1 mm high for S. domingensis versus 5.9-7.8 mm in diameter, 4.3-5.7 mm high for S. causiarum and 6.5-9.7mm in diameter, 4.5-6.2mm high, with a smooth (rarely some-what beaked) funicular remnant [for S. maritima]."

I have gotten a little confused reading that.
It’s giving height and Diameter for them? 

What are the size of palmetto in mm?

 

Sabal Domingenus; D 8.0-10.4, H 5.1-7.1mm

Sabal Causarium; D 5.9-7.8, H 4.3-5.7mm

Sabal Maritima; D 6.5-9.8, H 4.5-6.2mm

So what exactly does that last line ranslate to: smooth (rarely some-what beaked) funicular remnant [for S. maritima]."

is that the Protective seed outer pod?

Yes, makes sense to give height and diameter because the referenced seeds are not spheres but are round and flattened at the top.  Palmetto seeds are a bit more spherical in shape and Palmpedia lists them as 8 mm in diameter.  I believe what is meant by "funicular remnant" is the bump at the flat end of the seed where the seed connected to the ovary wall of the fruit.  On most Brahea seeds it is pretty obvious as seen in the photo below:

 

 

I have never examined them down to the mm before. Do ONLY Sabal Maritima seeds have that funicular remnant? I looked through the seeds and some still have the outer coating that looks JUST like the picture above.

No, not sure exactly what that quote from Palmpedia was really pointing out.  The flat side of the S. maritima seed might look somewhat different than other Sabal seeds but I doubt it.  In the photo below, the seeds at the top are S. mexicana and the one in the very center shows the flattened side face up showing the funicular remnant while the others are flat side down.  The photo above from my last post was a Brahea armata seed.
