CLEMATIS EMPRESS OF INDIA.-This Clematis belongs to the Patens section, and is certainly a striking variety when in bloom. I lately saw a finely flowered plant on a south-east wall in the old Abbey gardens, Winchester, which is situated right in the heart of the city, having lately been acquired by the Corporation, and laid out for the benefit of the inhabitants. The gardens are under the charge of Mr. Foot, and they certainly do him credit for the orderly manner in which they are kept. The flowers of the above Clematis are unusually large, and the colour most striking. The young blossoms are of a deep violet shade, parts of which lighten to puce as the flowers mature, finishing off with a purple bar on each petal.-E. M.
