3.6.11 Chadshunt 033 Cream coloured Ranunculus acris
Description:

Appears to be just an odd variant (not fading flowers - these were just opened) of Meadow Buttercup. There were about half a dozen plants with cream-coloured flowers in one patch of a meadow full of yellow buttercups. (The central shiny part was brighter yellow.) I've never seen any like this before. Unfortunately they're a bit blurred.

Seems to be a rare variant

Flower colour in buttercups seems to be remarkably constant. Presumably the cream colour is a breakdown in a biosynthetic pathway, but evidently it doesn't happen very often (as compared with the white-pink-blue sequence).

I have seen this in Ranunculus acris, and also once in Lesser Celadine (now Ficaria), but it is clearly very unusual.
