The botanical name reads like a compliment: Diospyros joins the Greek dios, divine, to pyros, grain, so the genus translates roughly as "fruit of the gods," a lofty title for a tree that drops sweet, homely orange fruit onto the forest floor each autumn. The common name travels the other direction, plain and American, from the Powhatan word putchamin for a dried fruit, a reminder that Native peoples were drying persimmons into cakes long before the botanists arrived.

Dirca palustris, the leatherwood, is a quiet native shrub with a hidden trick: branches so supple and tough they can be bent, twisted, even tied in a knot without snapping. That remarkable pliability, born of unusually soft, low-lignin wood, gave rise to the names leatherwood and ropebark, and made the bark a favorite of Native peoples for cordage. A slow, rounded, understory shrub of rich eastern woodlands, leatherwood is seldom offered and quietly prized by those who know it.
Distylium myricoides is an evergreen member of the witch-hazel family, Hamamelidaceae, and a quiet cousin to the fragrant winter witch-hazels, though the family resemblance hides in the flowers rather than the leaves. The genus name comes from the Greek for "two styles," for the paired styles at the heart of each small bloom, while the species epithet myricoides means "resembling Myrica," the bayberries, a nod to the narrow, leathery foliage.
Distylium racemosum is the type species of the genus and the most tree-like of the isu trees, an evergreen member of the witch-hazel family, Hamamelidaceae. The genus name comes from the Greek for "two styles," for the paired styles at the center of each small flower, while the species epithet racemosum notes the short racemes along which those flowers are held.
The autumn fern, Dryopteris erythrosora, earns the common name backward: the new fronds arrive in spring the color of turning leaves, a warm copper-orange that seems borrowed from October. As those fronds age they deepen through pink and bronze and finally settle into glossy dark green, so the plant carries a hint of autumn even at the height of the growing season.
Dryopteris ×australis is a fern that cannot, strictly speaking, reproduce, and is all the more vigorous for the lack. This is a natural hybrid, thrown wherever two Southern wood ferns grow within a spore’s reach of one another: the log fern, Dryopteris celsa, and the southern wood fern, Dryopteris ludoviciana. The cross comes out sterile, setting spores that never amount to anything, so the fern cannot seed itself across a bed the way a large fern usually will. Every plant in cultivation traces back by division to a wild clump found somewhere between Virginia and Louisiana, the greatest number of them in Alabama.
Oblongleaf twinflower, Dyschoriste oblongifolia, is a low, spreading wildflower of the American Southeast, a member of the acanthus family that carpets the dry pine flatwoods, sandhills, and open savannas of Florida and neighboring states. The common name comes from the habit of carrying the small, funnel-shaped flowers in pairs, twinned in the leaf axils along low stems, while the botanical epithet oblongifolia simply describes the neat, oblong leaves. An older regional name is snakeherb, a tag shared across the genus Dyschoriste.
