Its leaves are pale green with silvery lines beneath. P. sylvestris (Scotch Fir) is a handsome, very hardy Fir, too well known to need more than passing reference. It thrives on all soils, is of rapid growth, and very cheap. P. s. aiirea (Golden Scotch Fir) is very attractive, especially in winter ; it is a slow-growing variety, and although its leaves are usually of a pale green "shade in summer, they assume a rich yellow in winter, at which season it is unquestionably the bright- est of golden - coloured Conifers. An open situ- ation should be afforded it, and a dry rather than a moist soil suits it best. P. s. fastigiata (Fig. 324) is conspicuous for its Lombardy Poplar - like habit, and is worthy of recognition. P. s. globosa is a small, very compact, much-branched tree, with glaucous leaves, distinct, and very slow in growth. P. Thujibergi is a Japanese species, and rather rare in this country. It is a vigorous grower, with short, stout branches, and stiff deep green leaves ; it pre- fers a sheltered situation. P. T. variegata differs from the type in the lower portion of its leaves being marked with yellow, a constant colour which im- parts a distinct appearance to the tree. PoDOCARPUS.—This is a large genus, scattered over Australia, China, Japan, Africa, &c. The majority of the species are, however, not sufficiently hardy to withstand the open air in this country. They succeed best in a moist, loamy soil, but water should not become stagnant at the roots. A position screened from east winds should, if possible, be selected. Those species here mentioned are the hardiest and most serviceable for the garden. P. alpina, a Tasmanian shrub of humble growth, is very rare in this country, even in good collections of Conifers.
