Hardy American deciduous shrubs, with the appearance of Amentacese, to which they are undoubtedly 

 closely allied, notwithstanding their situation here, which must be considered quite artificial. Nothing is 

 known of their medicinal qualities. Cuttings, layers, and seeds.

These bear the same relation in point of consequence to resinous trees, that Amentacea? bear to those that 

 are not resinous. They are well known as lofty timber, yielding valuable wood and abundance of resin. 

 Among them is now numbered the loftiest tree in the world, a species of pine found by Mr. Douglas in 

 California, which grows 220 feet high, with a circumference of 60 feet. Pitch, turpentine, Venice turpentine, 

 are produced by various species. Gum Sandarach, by Thuja quadrivalvis ; a matter like olibanum, by Juniperus 

 lycia; a sort of liquid storax, by Alt'mgia excelsa. The Juniperuses in which the resin is "incompletely 

 oxygenised " are more fragrant, and also stimulating in a greater degree ; as the savin, for example. The 

 berries of many of these plants possess similar qualities. Their seeds are all oily ; those of Pinus Pinea, 

 Cembra, and Lambertazrca, and Salisbury adiantiiblia, are eatable as nuts. The fleshy fruit of the yew, which 

 is poisonous, is an exception to the general innoxious character of the order. Conifera? are mostly inhabitants 

 of the northern parts of the world, where they form immense forests, and supply with their dense persistent 

 leaves the place occupied by the evergreen trees of warmer climates. A few are found in the southern 

 hemisphere. Layers and seeds, sometimes by cuttings.

The physiological peculiarities of this class of plants have been already explained in the general remarks 

 which precede this arrangement of natural orders. To what is there stated, little remains to be added, except 

 that in these northern regions, every thing included in it is herbaceous, and that in hotter latitudes, few 

 deserve the name of either bush or tree, except the palms, and a few Arbideaa and Asphodelea?.

The true station of this very curious order is extremely uncertain. Although placed here in conformity 

 with the common practice, it is to be supposed that its true station is in the immediate vicinity of ferns, with 

 which the species agree in vernation, and in many curious particulars. All are natives of countries beyond 

 the reach of frosts, chiefly of the Cape of Good Hope and equinoctial America. With a low trunk, which 

 rarely exceeds the height of a few inches, they have the fronds and appearance of pygmy palms, and the 

 inflorescence of gigantic Equisetums. The trunk of Cycas contains a great quantity of faecula, which is 

 manufactured into a kind of spurious sago; and a similar substance, it has lately been ascertainedj may be 

 obtained from the stem of Cycas. (Gard. Mag., vol. iv.) Scales.
