Taken at a birch forest in Petropavlovsk-kamchatsky, Russia. Not in any of our books. Internet of no help. Only a single pic of this small 6 petal white flower. No idea what to make of the white blobs in the centre. Please can anyone help with an id. Thank you.
Check this page in Plantarium: http://www.plantarium.ru/page/samples/taxon/44223.html Maybe Arsenjevia will fit.
Thanks Daniel, Hmm! I had discounted Anemone because of the thin looking leaves. But maybe that is all it is.
Thanks Andrey.....great link. May prove very useful. Don't think it is Arsenjevia as the leaves look very different. https://www.google.co.uk/search?nfpr=1&q=Arsenjevia&tbm=isch&ei=MHeqU6-uJaOG0AXZz4CoDw
Yes, that's a very good site. For comparison, check out Anemone trullifolia on that site. I don't think that's it, but maybe something close?
Thanks for the suggestion Daniel. Anemone trullifolia is one of the lovely Anemones that we used to grow. The leaves are very distinctive, a basal rosette of quite heavy leaves, from which the flowers grow. All our flowers had 5 petals. The numerous filaments and anthers were yellow and contained within the petals Mystery flower struck me as rather different from anything I had seen before or seen pics of in books/www. It was the only specimen that I saw. 6 white petals. The 15 or so filaments were white, with big, pure white anthers that seem to be forming a protective cage over the pistils below....finding it hard to put this into words! I originally thought it had individual thin strap leaves...but could be very wrong about that.
Those are probably bracts like in other Anemone species. Leaves should be mostly basal and not seen in the picture.
