The genus _Calanthe_ which we now again bring under the notice of our readers, ranks amongst the most useful in cultivation for winter decoration. Several species and varieties have been introduced within the last few years, and have proved to be a great boon to plant growers and others who are fond of flowers, as the whole of this bulbous class produce their blossoms at a time when the beauties of nature are most appreciated. What can be more charming than the original _C. vestita_, and its red-eyed and yellow-eyed varieties with their drooping flower spikes; or what more pleasing than the _C. Veitchii_, figured at Plate 31 of our first volume, a hybrid raised by the Messrs. Veitch & Sons, of Chelsea, and a most useful decorative plant, its long spikes of rich rose-pink flowers producing a most charming effect when intermixed with the white-flowered kinds. We have now another variety to make known, and one which, as will be seen from the accompanying figure, adds a new charm to the genus, since it will introduce among our winter blooming Calanthes a most distinct and showy form that will be welcomed by all plant growers as being superior in beauty to all those which have preceded it. It has been named in compliment to Mr. B. S. Williams, of Holloway. Our drawing was taken from a plant that had been blooming during the months of December, January and February in the Victoria and Paradise Nurseries. It seems to be of free growth, the pseudobulbs being like those of _C. vestita Turneri_, the spikes of flowers being also of similar character and developed at the same time of year. _Calanthe vestita Williamsii_ is a deciduous plant, with pseudobulbs from five to eight inches in height, and leaves a foot high and of a light green colour. The flower-spikes, which are produced from the base of the bulb, are two feet or more in length, and bear many flowers; the sepals and petals are white, faintly margined and striped with bright rosy crimson; the lip and column are of a deep rosy crimson, with an intense crimson eye. It continues to flower on for three months, when the bulbs are strong. This novelty requires the same mode of treatment as that recommended for _Calanthe Veitchii_ at Plate 31 of our first volume, where full cultural instructions are given.
