A genetic mutation known as Tetralogical Water Avens

I think the word is teratological, from the ancient Greek verb 'teratologeo' - 'to tell of strange phenomena'. The noun 'teras' means 'a marvel'.

'tetra' is a prefix for 'four' and is not referred to here.

Teratology is the study of monstrous forms of animals and plants.

Thanks for putting me right

Thanks for putting me right and the insight into the meaning. I should have not been so lazy and rechecked the spelling. However, in my not doing so I may never have gained this information. Thanks again
