One of the most valuable plants for greenhouse decoration is the Libonia flori bunda, which was introduced only a few years ago. It is a small, half-shrubby plant, which, on account of its abundant and persistent flowering all winter, is especially useful in the cool greenhouse, or under certain circumstances as a window-plant. We have recently received from Mr. John Saul, of Washington, another Libonia, which appears to be an improvement on the older one. It has better foliage, and much larger, brighter, and deeper colored flowers than the other, and is, on these accounts, preferable to it. This new Libonia is called L. Penrhosiensis. It is said to be a cross between floribunda and Sericographis Ghiesbregtiana, a statement we do not credit, as the difference between it and L.fIoribunda is no greater than often happens with seedlings. Whatever may be its origin, it is an exceedingly bright and pretty plant. The flowers are vermilion red at the base, shading into yellow at the upper part. The Libonias are not suited for cut-flowers, as the blossoms drop very readily.

If grown as a window-plant, it should be commenced with in the fall, and brought into flower in the window, as plants taken from a greenhouse into the dry air of a dwelling lose both flowers and leaves, and become unsightly. - Hearth and Home.
