I have a lot of casuarina growing near me. Most are glauca, but also Allocasuarina littorals and equisetifolia.
I had trouble identifying them down to species until I bought a magnifier for my iPhone:

Cost me about $15 on eBay.

This allows me to take macro shots of the tiny leaves on casuarina which helps me when using an online key to identify them. Close photos of the seed pods and flowers also help with ID. Here is a photo taken of a branch which I pulled apart so the leaves can be seen and counted: I also use the lens to get a closer look at pests and irregularities on my plants.
Thought it was worth sharing.

wow, thats cool. But I'd use that to find the illusive lego pieces that get eaten by our couches.

Hi
I found two Casuarina's with 8 . But my book does not show Equestafolia

This is the online key I use for ID. Plantnet
I haven't tried to further ID the tree I took the above sample from, as it had no flowers or "cones". I will come back to it later in the year to identify it and maybe take some seeds.
