Need Id please

This plant stands about 6-8 inches tall. It has a strong very pleasant Lemony Citrusy scent. Please ID Thank You In Advance:)

 

Casuarina seedling?

 

Thanks for the input Michael :) I don't think that's it. These appear to be perennials herbs or weeds of some sort. They die back in the fall and pop up in the summer. I have never seen it grow larger than maybe 8-10" tall. Never any flowers or leaves that I have seen. There are about 8 of these plants growing in a small area. The closest resemblance I have found is mormon/brigham tea. But that is not native to this area, grows much taller and I don't think brigham tea has a citrus orange and lemon kind of smell.
Anyone have any idea? Thank You for looking:)

 

All I can think of is field horsetail. Have never gotten a citrus aroma from that.

 

Ok I just did some googling of horsetail and none of the images match what I have. also tried citrus scented horsetail in google and came up with nothing except mandarin orange and horsetail shampoo lol. I have also googled "citrus scented herb" and "citrus scented plants" I have looked at many different images and plant descriptions. I don't know this one has me stumped. Thanks for the input though. It must be very uncommon whatever it is. I have this habit of walking around the yard and trying to identify plants. I always break off a small piece and smell it. This one has a strong citrus smell. I just smelled it again and I would say it smells more like orange than lemon. Maybe I will pull one up roots and all and post a new image tomorrow.

 

I dug up one of these plants. I am not sure if I got all the roots. Here are a couple of new images.

 

Definitely not a horsetail, they have whorled, not opposite, leaves and branching.

Maybe something in the family Caryophyllaceae? Check the genera Bufonia, Gypsophila, Moehringia, and Petrorhagia for options.

Do they ever produce flowers?

 

Thank You for the input Michael. I will research the information you have given me. Do you have any recommendations for the best website that would have good pictures I could take a look at? Thank You for your time:)

And to answer your question I have not seen any flowers.

 

Google images is as good as any for finding pics of a named item

 

The way this plant looks, I'd certainly go with Casuarina or Equisetum, but you've ruled them out.

Next, I'd be wondering about your environment in FL. Google images of seablite and salicornia to see if either of them would fit. Both are salt tolerant seaside plants with extreme variability in appearance.

The picture on the wikipedia page on salicornia looks a bit like your plant, but the pic on the Suaeda or seablite page doesn't at all.

I know some of these maritime herbs are strongly scented. They are also succulent, which your pictured plant may not be.

 

Could it be some kind of ephedra?
