Messrs. Lucombe and Pince's advertisement, at page 561, reminds me of an opinion I was led to form on receiving from them lately fine specimens of the above named plant - that Begonias must soon become as popular as Achimenes, Gloxinias, and the like, now that the process of hibridization has been so successfully brought to bear upon them. Ton will, perhaps, allow me to mention, for the information of those who have not seen it, that this B. Prestoniensis is probably the handsomest of the Begonias - certainly one of the most brilliant; so that it must become a popular plant It is said to come from B. cinnabarina crossed with B. nilida, and unites with foliage and flowers very much like those of the former the shrubby character of the latter, so far modified as to be literally of a neat branched habit of growth; the leaves are obliquely ovate-acuminate, slightly lobed, and doubly-serrate on the margin, and the flowers come along the branches in axillary trichotomous cymes, elevated on long red peduncles above the dark green leaves. These flowers (male 4-petalled, female 6-petalled) are, perhaps, rather smaller than in B. cinnabarina, but brighter colored, and they have unquestionably a very pleasant rose-like odor, which was discoverable after a long railway journey.

It is a true Diplo-clinium, not a Platyclinium, like its female progenitor, having the placentas double. A figure of it will be published in the forthcoming, and, I believe, final number, of the Garden Companion. - Thomas Moore, in Gardeners* Chronicle.
