Messrs. D. Landreth & Fulton, of Philadelphia, who are extensively engaged in the culture of this charming plant at the old Landreth Nurseries, where was made the earliest collection of the Camellia in America, present the following as a desirable selection. Those marked + are perfectly double, with the petals neatly arranged, and are among the choicest in cultivation. Those marked with a star are of American origin.

The catalogues of some European Nurserymen contain upwards of five hundred varieties; it may be readily presumed that many of them are comparatively worthless: a goodly number of such have been imported by the American florists, and though some of them were once esteemed, are now, by the introduction of more desirable varieties, no longer worthy a place in a choice collection. We append a list of a few such faded beauties.

Cameraria

Dr. Lindley, writing of their propagation, says: - "Either sow the seeds, or pot cuttings" from the old roots, in leaf mould and sandy peat; as soon as they are strong enough, pot them off in sixty-sized pots regularly, shifting them into larger sizes as the plants require them; when they have gained a little strength, give them a rich loamy soil, well incorporated with a small proportion of bone dust, and at intervals supply them liberally with manure water." - Gard. Chron.

C. iridiflora is the most splendid; a writer in the Gardener's Chronicle says, that "so far from requiring stove heat, few plants cultivated in a green-house are more hardy. It only requires protection from frost, and the border of the conservatory is its proper place, where it continues growing, with the thermometer varying between 35° and 45°".
