"A lover of wild flowers" writes : The inclosed specimen I have thought to be a double variety of Thalictrum anemonoides. The plant grows from three to four inches in height, and has no stem leaves except those that form an involucre around the umbel of flowers which are full double, pure white, and very pretty. Will you please examine and answer as to the correctness of this name in the Gardeners' Monthly".
