Siberian Snow Flower

Please, can someone ID this flower.

I came across this description in a book that was published in 1891.

"One of the papers tells of a newly discovered flower. It is called the snow
flower. It has been found in the northern part of Siberia. The plant shoots
up out of the ice and frozen soil. It has three leaves, each about three
inches in diameter. They gown on the side of the stem toward the north. Each
of the leaves appears to be covered with little crystals of snow. The
flower, when it opens, is star shaped, its petals being of the same length
as the leaves, and about half an inch in width. On the third day the
extremities of the anthers show minute glistening specks, like diamonds,
which are the seeds of this wonderful flower."

The normal Google searches have failed, so has browsing botanical web pages.
Any help would be appreciated.

Thanks
