PLATE XI
NARROW-LEAVED SPLEENWORT
a Magnified pinna of fertile frond
Late in August the plant has reached a stately height, perhaps of three or four feet. The fronds are still smooth and delicate to a degree unusual even in ferns. But they wear a deeper green, and their texture seems a trifle more substantial. Occasionally, though rarely in the deeper woods, we find a frond which is conspicuously longer-stalked, taller, narrower than the others, with pinnæ more distant and more contracted. A glance at its lower surface discovers double rows of brown, linear fruit-dots.
Though one of the largest of its tribe, the Narrow-leaved Spleenwort suggests greater fragility, a keener sensitiveness to uncongenial conditions, than any other of our native ferns. A storm which leaves the other inhabitants of the forest almost untouched beats down its fronds, tender and perishable even in maturity.
This very fragility, accompanied as it is with beauty of form and color, in the midst of the somewhat coarse and hardy growth of the August woods, lends the plant a peculiar charm.
I find it growing beneath great basswoods, lichen-spotted beeches, and sugar maples with trunks branchless for fifty feet, soaring like huge shipmasts into the blue above.
Almost the only flowers in its neighborhood, for in midsummer wood-flowers are rare, are the tiny pink blossoms of the herb Robert, that invincible little plant which never wearies in well-doing, but persists in flowering from June till October, the violet-blue heads of the almost equally untiring self-heal and the yellow pitchers of the pale touch-me-not or jewel-weed. This plant, a close relative of the more southern and better known spotted touch-me-not, grows in great patches almost in the heart of the woods. The lack of flowers is somewhat atoned for by the coral clusters of the red baneberry and the black-spotted, china-like fruit of the white baneberry.
But ferns chiefly abound in these woods. Everywhere I notice the thin, spreading frond and withered fruit-cluster of the Rattlesnake Fern, in my experience the most ubiquitous member of the Botrychium group. More or less frequent are graceful crowns of the Spinulose Shield Fern, slender shining fronds of Christmas Fern, dull-green groups of Silvery Spleenwort and stately plumes of Goldie's Fern. As we draw near the wood's border, where the yellow sunlit fields of grain shine between the tall maple shafts, we push aside umbrella-like Brakes. At the very limits of the woods, close against the rails, grows the sweet-scented Dicksonia.
