At Mr. Buist's establishment, near Philadelphia, may be seen the new Thuja Borealis, which promises to be an important addition to our list, and is hardy. There has been some error in naming the Thuja gigantea; the decurrens has been sold for the gigantea, and vice versa. Now the real gigantea of Rivers (heretofore called decurrens) is hardy, but decurrens (sold for gigantea) is tender here. It will be well to remember this.

Dracaena speciosa variegata is an improvement on terminalis; this and nobilis will hold a superior rank to all others yet introduced.

Thuja #1

Aurea, beautiful; untouched. - Thuja variegata, untouched. - Thuja Orientalis, perfectly hardy. - Thuja Siberica, perfectly hardy. - Thuja Plicata, perfectly hardy. - Thuja Pendula, or flliformis, very hardy, and very desirable. .

Thujas #1

Among the Thujas, (Arbor Vitae,) Hoveyi, (Hovey's,) cristata, (Buist's Seedling,) gigantea, glauca, and Craigeana are perfectly green, and have been so all winter; and even Podocarpus nubigena holds its color and health perfectly well.


Wellingtonias are somewhat browned, but wood and buds good.

Among the Evergreen gains of the past year, I consider the most important, Cupressus Lawsoniana, Taxus elegantissima, Podocarpus nubigena, Berberis Japonica, Taxus monstrosa, Taxus microphylla, Pinus Jeffreyi, Pinus Beadsleyi, Pi-nus Sabiniana; and among the named Rhododendrons are Azureum, Sir Charles Napier, Bicolor, Grandissimum, Concessum, Vandyke, Barclayanum, Delicatissimum, Ccelestimfm, Brayanum, Multimaculum, Achimedes, Magnificum, Prince Albert, Lord John Russell, all of which are entirely uninjured and well set in flower-buds.

[We are all under deep obligations to Mr. Sargent for his valuable observations on introduced Conifers and evergreen plants. The results of his labor and devotion possess a practical value for all of us which can not be estimated too highly. It were much to be wished that we had a corps of such liberal-minded men at various points throughout the country; the collected results of their observations would possess a deep and wide-spread value. We know of no way in which they could spend a portion of their wealth with more pleasure to themselves and profit to the public. Mr. Sargent gives us a sad picture of the results of the winter in England, but by no means overdrawn; he might, indeed, have painted it in still deeper colors, if we are to form an opinion from the English Horticultural press. Standard Roses, Grape-vines, and other plants come within the same category. We think Mr. S. has assigned the true cause of all this desolation, in the non-ripening of the wood last fall; and to the same cause we have elsewhere ascribed the loss of our fruit-buds during the past winter; the cause of non-ripening in this case, however, is to be assigned more, perhaps, to the overbearing of the trees last season, than to the cold fall, early winter, or sudden and extreme variations of temperature.

The whole subject is very suggestive. - Ed].
