Part 18

Var. frondosa is an occasional form in which some of the fruiting fronds have green, leaf-like pinnæ below. These abnormal fronds are most abundant on land which has been burned over.

The Cinnamon Fern is a member of the group of Osmundas, or "flowering ferns," as they are sometimes called, not of course because they really flower, but because their fruiting fronds are somewhat flower-like in appearance. There are three species of Osmunda: the Cinnamon Fern, O. cinnamomea; the Royal Fern, O. regalis; and the Interrupted Fern, O. Claytoniana. All three are beautiful and striking plants, producing their spores in May or June, and conspicuous by reason of their luxuriant growth and flower-like fruit clusters.

The Osmundas are easily cultivated, and group themselves effectively in shaded corners of the garden. They need plenty of water, and thrive best in a mixture of swamp-muck and fine loam.

4. CURLY GRASS

Schizæa pusilia

Pine barrens of New Jersey.

Sterile fronds.--Hardly an inch long, linear, slender, flattened, curly.

Fertile fronds.--Taller than the sterile fronds (three or four inches in height), slender, with from four to six pairs of fruit-bearing pinnæ in September.

Save in the herbarium I have never seen this very local little plant, which is found in certain parts of New Jersey. Gray assigns it to "low grounds, pine barrens," while Dr. Eaton attributes it to the "drier parts of sphagnous swamps among white cedars."

CURLY GRASS]

In my lack of personal knowledge of Schizæa, I venture to quote from that excellent little quarterly, the Fern Bulletin, the following passage from an article by Mr. C. F. Saunders on Schizæa pusilla at home:

"S. pusilla was first collected early in this century at Quaker Bridge, N. J., about thirty-five miles east of Philadelphia. The spot is a desolate-looking place in the wildest of the 'pine barrens,' where a branch of the Atsion River flows through marshy lowlands and cedar swamps. Here, amid sedge-grasses, mosses, Lycopodiums, Droseras, and wild cranberry vines, the little treasure has been collected; but, though I have hunted for it more than once, my eyes have never been sharp enough to detect its fronds in that locality. In October of last year, however, a friend guided me to another place in New Jersey where he knew it to be growing, and there we found it. It was a small open spot in the pine barrens, low and damp. In the white sand grew patches of low grasses, mosses, Lycopodium Carolinianum, L. inundatum, and Pyxidanthera barbulata, besides several smaller ericaceous plants and some larger shrubs, such as scrub-oaks, sumacs, etc. Close by was a little stream, and just beyond that a bog. Although we knew that the Schizæa grew within a few feet of the path in which we stood, it required the closest sort of a search, with eyes at the level of our knees, before a specimen was detected. The sterile fronds (curled like corkscrews) grew in little tufts, and were more readily visible than the fertile spikes, which were less numerous, and, together with the slender stipes, were of a brown color, hardly distinguishable from the capsules of the mosses, and the maturing stems of the grasses which grew all about. Lying flat on the earth, with face within a few inches of the ground, was found the most satisfactory plan of search. Down there all the individual plants looked bigger, and a sidelong glance brought the fertile clusters more prominently into view. When the sight got accustomed to the miniature jungle quite a number of specimens were found, but the fern could hardly be said to be plentiful, and all that we gathered were within a radius of a couple of yards. This seems, indeed, to be one of those plants whose whereabouts is oftenest revealed by what we are wont to term a 'happy accident,' as, for instance, when we are lying stretched on the ground resting, or as we stoop at lunch to crack an egg on the toe of our shoe. I know of one excellent collector who spent a whole day looking for it diligently in what he thought to be a likely spot, but without success, when finally, just before the time for return came, as he was half crouching on the ground, scarcely thinking now of Schizæa, its fronds suddenly flashed upon his sight, right at his feet. The sterile fronds of Schizæa pusilla are evergreen, so that the collector may, perhaps, most readily detect it in winter, selecting days for his search when the earth is pretty clear of snow. The surrounding vegetation being at that time dead, the little corkscrew-like fronds stand out more prominently."

GROUP II

FERTILE FRONDS PARTIALLY LEAF-LIKE, THE FERTILE PORTION UNLIKE THE REST OF THE FROND

5. ROYAL FERN. FLOWERING FERN

Osmunda regalis

New Brunswick to Florida, in swampy places. Two to five feet high, occasionally taller.

Sterile fronds.--Twice-pinnate, pinnæ cut into oblong pinnules.

Fertile fronds.--Leaf-like below, sporangia forming bright-brown clusters at their summits.

Perhaps this Royal or Flowering Fern is the most beautiful member of a singularly beautiful group. When its smooth, pale-green sterile fronds, grown to their full height, form a graceful crown which encircles the fertile fronds, it is truly a regal-looking plant. These fertile fronds are leaf-like below, and are tipped above with their flower-like fruit-clusters.

Like its kinsmen, the Royal Fern appears in May in our wet woods and fields. The delicate little croziers uncurl with dainty grace, the plants which grow in the open among the yellow stars of the early crow-foot, and the white clusters of the spring cress being so tinged with red that they suffuse the meadows with warm color.

Though one of our tallest ferns, with us it never reaches the ten or eleven feet with which it is credited in Great Britain. The tallest plants I have found fall short of six feet. Occasionally we see large tracts of land covered with mature plants that lack a foot or more of the two feet given as the minimum height. This tendency to depauperization one notices especially in dry marshes near the sea.

ROYAL FERN

To the Royal Fern the old herbalists attributed many valuable qualities. One old writer, who calls it the "Water Fern," says: "This hath all the virtues mentioned in other ferns, and is much more effective than they both for inward and outward griefs, and is accounted good for wounds, bruises, and the like."

The title "flowering fern" sometimes misleads those who are so unfamiliar with the habits of ferns as to imagine that they ever flower. That it really is descriptive was proved to me only a few weeks ago when I received a pressed specimen of a fertile frond accompanied by the request to inform the writer as to the name of the flower inclosed, which seemed to him to belong to the Sumach family.

The origin of the generic name Osmunda seems somewhat obscure. It is said to be derived from Osmunder, the Saxon Thor. In his Herbal Gerarde tells us that Osmunda regalis was formerly called "Osmund, the Waterman," in allusion, perhaps, to its liking for a home in the marshes. One legend claims that a certain Osmund, living at Loch Tyne, saved his wife and child from the inimical Danes by hiding them upon an island among masses of flowering ferns, and that in after years the child so shielded named the stately plants after her father.

The following lines from Wordsworth point to still another origin of the generic name:
