Mr. Sereno Watson thus describes a new Californian Conifer: Branches slender, often elongated and pendant, puberulent; leaves 5 to 12 lines long, ½ to nearly I line wide, strictly sessile upon the slender base, obtuse, smooth and rounded or slightly carinate above, stomatose beneath on each side of the slightly prominent mid-nerve; cones inches long, narrowly cylindrical, attenuate at base; bracts linear-oblong (2 inches long), a fourth of the length of the puberulent scale, which is obovate, with the rounded thickish summit entire; seed 1½ lines long, the wing 4 lines long by 2½ broad. This unusually distinct species has been found (by Thomas Howell, in June, 1884), only at high elevations in the Siskiyow Mountains, California and on the head waters of the Illinois river, in rather dry rocky ground. It grows to a height of from 100 to 150 feet, and a diameter of 1 to 3 feet. Bark reddish. The specific name is given in compliment to Professor W. H. Brewer, who in connection with the California State Geological Survey had so much to do with the botany of the State, both in the field, and in the after disposal of the collections of the Survey. As he took special interest in the trees of the coast, and collected a large amount of material for their study, it is fitting thus to connect his name with the forest trees of California. - Proc. of the Amer. Acad., 1884,p.378.

Cedrela Sinensis - is the only member of a genus of large trees which is hardy in this country. Jamaica or West Indian Cedar is furnished by C. odorata, which is cultivated in stoves or greenhouses in this country; and the timber of C. Toona, largely used in Australia and India for furniture and general ornamental work, is also grown in England under similar conditions. At Kew, however, C. sinensis seems as hardy as the Ailantus glandulosus, which it much resembles in general aspect. It was introduced from China to the Jardin des Plantes, at Paris, rather more than a score of years ago, and for a long time was known in nurseries under the name of Ailantus flavescens. ' It, however, does not possess the strongly disagreeable odor of the foliage of the Ailantus, and the whole plant has a yellower hue. The roots, too, are red and not white, as in the Ailantus. Like that, it is readily propagated by means of root cuttings, and, in rapidity of growth and general adaptability for decorative purposes it seems likely to rival the Ailantus. - Garden.

The Fastigiate Birch (Betula alba var. fas-tigiata) - should find a place in every park and in every collection of ornamental deciduous trees. It is the exact counterpart among the birches of the Cypress oak among the oaks. In addition to the peculiarity of its columnar habit of growth, it has the merit of retaining its dark green foliage much longer than any other variety of our native birch, and indeed longer than perhaps any other cultivated species. I am at present ignorant of the history or origin of this interesting tree; it is in all probability a somewhat recent sport; at any rate, it was unknown to Loudon. - Garden.
