There is no necessity for repeating the particulars already given respecting the Cedar of Lebanon, and which apply to the Deodar with such modifications as are indicated in the first paragraph above. Specimens grown where they have sufficient space for spreading out their long arms, retain their branches to the base of the trunk, and if these are cut off they can reproduce them. Several nursery varieties--with golden (_aurea_), silvery (_argentea_), or more intense green (_viridis_) foliage than the type--have appeared as a result of European cultivation. * * * * * [Illustration: _Pl. 173._ Lawson's Cypress.] Lawson's Cypress (_Cupressus lawsoniana_). Lawson's Cypress belongs to that section of Conifers which includes the Junipers and Thuias, and is a representative of the North American Sylva. It is a native of South Oregon and North California, where it is believed to have been first discovered by Jeffrey, about 1852. Two years later seeds were received by Messrs. Lawson, the Edinburgh nurserymen, from Mr. William Murray, and from these seeds were raised the first young trees of this species sent out by the firm. The name was bestowed in honour of Mr. Charles Lawson, the then head of the firm, and by this name it is generally known in Europe, but in the United States it is the Port Orford Cypress. At Port Orford, on the Oregon coast, according to Sargent, "it forms one of the most prolific and beautiful coniferous forests of the continent, unsurpassed in the variety and luxuriance of its undergrowth of Rhododendrons, Vacciniums, Raspberries, Buckthorns, and Ferns," and any one who has seen well-grown specimens in the pleasure-grounds of this country can easily realize something of the beauty of such a forest, though allowance has to be made for the fact that in forest growth the lower branches are lost at an early age. [Illustration: Lawson Cypress.] In its native home the Lawson Cypress attains a height of between 120 and 150 feet, occasionally reaching 200 feet, with a base circumference of 40 feet. The thick brown bark splits into rounded scaly ridges. The short horizontal branches divide a good deal towards their leafy extremities, which are curved, and commonly drooping. The leaves are little evergreen scales, which overlap, and being closely pressed to the branchlet, completely clothe and hide it. They are bright dark-green in colour, and endure for three or four years. The male flowers are produced at the tips of short branchlets, formed a year earlier. They are of cylindric form, crimson in colour, and each stamen bears from two to six anther-cells. The small "cones" are more or less globular, but instead of a large number of spirally arranged overlapping scales, as in the Pines and Firs, here there are only eight, whose edges at first join to form a box. When the "cone" is ripe these scales separate, to allow the escape of the seeds.
