The few hints which I am about to offer upon these, are such as we have practiced with such satisfactory and beneficial results, that I heartily commend them to all in possession of an ordinary greenhouse; feeling sure that they will be rewarded with gratifying results for their labor.

Not only are Selaginellas easy of culture, but they delight in situations where the generality of plants would linger and die. Underneath the benches of the greenhouse, or any place where a certain amount of filtered light can reach them, with plenty of moisture, they are at home; thus utilizing and beautifying such situations as are often receptacles for rubbish. But although moisture-loving plants, drainage and a free soil is a point of paramount importance in their culture, as, owing to the necessity of frequent waterings, unless the superfluous moisture can pass off freely, damping is almost sure to take place. Underneath the benches we put cinders, broken bricks, or anything to form drainage. That under the side benches we slope from side of greenhouse to walk-way, and that under the center bench we put in the form of a ridge, thus making it slope to walk-way on both sides. Upon this is laid about four inches of rich free soil. If a few bits of Selaginella Krausiana, be now dibbled in a few inches apart it will soon take root and form a verdant bank ever fresh and beautiful, and which even the dullest days of winter have not the power to dim.

The position of pipes or flues in some greenhouses may not admit of the above arrangement, but few can be found without some nook to which the same idea could be beneficially applied. I have recommended S. Krausiana as it is one of the very best, being of a hardy enduring character, and few greenhouses are to be found without it. Under the above treatment it makes luxuriant growth, and will be found useful for many purposes. As a covering for the top of pots used in house decoration, if a few handfuls be taken up with some soil attached it will thus form an immediate carpet of the richest verdure. This combination with flowering and bright foliage plants has a very pleasing effect. There are also many more varieties well deserving a place, and a collection of a dozen or so varieties, will in themselves, form an attractive feature in any greenhouse, exhibiting as they do a considerable variety of foliage. Martensii and its variegated form seems to enjoy the freedom of being planted out by the high state of luxuriance which it attains. This is very desirable for mixing with cut flowers, standing fresh for a long time in water. Then comes the lovely S. Coesia with its rich metallic fronds, sometimes attaining a yard in length.

This makes a beautiful basket plant, the fronds of which should be shorn close off every spring, when it will commence to grow with renewed strength and vigor. The same remark applies to all dense growing Selaginellas, otherwise they soon show signs of decay, and recourse must be had to planting over again; but if this cutting back is annually attended to they will remain in good condition, in the same position for years. S. Densa and Poulterii are very desirable kinds of dense habit; S. Krausiana aurea, a golden variety, should be in every collection. Wildenovii, a variety with fern-like fronds is very pretty. But it is a difficult matter to make a selection of one better than another, for they are all interesting and beautiful, and one can scarcely go amiss in choosing a collection. South Virginia.
