Oh I'm flattered, I'm far from expert, but the whole appearance of the flower stalk, the gray covering of the leaves and the cup shaped leaves around the flowers aren't inherent traits of cypress spurge, so I confirm my opinion.

I meant the real grass in the first picture. ;) :D

Polyploidism is harmless to plants. Also this is the theory of the development of some species. Plus it affects the whole plant not just one flower stalk. The cristate forms are formed when the apex goes wild and start branching in very high speed, in the end you have so many branches that there is not enought space to split so they stay fused. There was one very good explanation about this forms in one of the cacti and succulents sites, but I can't find it now.

Very interesting! At first side I thought that this is not a mutation, but it's just a lack of some important element in the soil. Тhen I saw near it there are normal looking too, so this might be a mutation which blocks the assimilation and because of that the chlorophyll cant be well produced.
PS: Lovely grass, please, make another spotting specially for it. ")

Wow are they on the same flower stalk? Fascinating!

The tail is not a mutation, but regeneration. At some point the lizard lost it and then it can regenerate. It can't be full regeneration, but just to have something to drop when feel threatened. Even though thank you for posting it in my mission. :)

The species name must be written with small letters only. ;)

Don't worry, I couldn't see any reproductive organs so it was lost anyway if it's annual. You can make herbarium if you found the rest of it. :)

It's not that species. The leaflets of C. hirsuta aren't lobed.

You must wait for the fruits to be 100% sure, there are several other look-a-like species. ;)
