A well known species, beautifully variegated. Like the preceding one, it is a strong grower and soon monopolizes more than its due share of room, still it should find a place in every fernery, as it is a most effective and charming plant. For soil' use two parts peat, one part loam, and half a part each charcoal and silver sand.

P. cretica alba-lineata, another popular variegated species, making a lovely contrast when planted among other ferns of a more sombre hue. Soil same as for P. argyraeaa.

P. longifolia, a particularly noble-looking and graceful fern, succeeds well under ordinary treatment, growing freely in fibry peat having a liberal admixture of silver sand.

P. serrulata, one of the most common, and at the same time one of the prettiest, in the whole genus, its bright, green, graceful fronds making it a most invaluable adjunct to every fernery. In fact, it is almost as necessary as Adiantum cuneatum, for cutting for bouquets and table decorations. It grows freely in almost any soil, but I have found it to do best in a compost consisting of two parts peat with one part loam, and one part leaf mould, and some silver sand. It and the preceding species will seed themselves over the fernery in a short time; indeed, I have often found them rather troublesome in this respect. There are several crested forms of P. serrulata, all of them being more or less beautiful.

P. tremula and P. umbrosa make noble specimen plants, but are altogether too robust, except for extensive ferneries where there is plenty of room to spare.

I fear to extend the list further, not but that there are hosts of others of equal beauty with those I have already named, but I consider I have drawn attention to a sufficient number for a beginner in fern growing to make a start with, and if to those he adds a few Selaginellas, such as S. denticulata, S. Wildenovii, S. Africana, S.densa, S. sto-lonifera, and S. involvens, he will have ample material wherewith to fully stock every portion of his fernery.
