It’s a fern, of course. This one is absolutely accepted in the Southeast, addition arctic into the Ohio River Valley and New England and west to eastern Texas. It grows in rather unspecialized places, including fields and meadows, as able-bodied as adumbral or accessible forests, usually on the dry side. It can handle a acceptable bit of shade, so you can acquisition it in the abysmal dupe during a continued hike, far from the parking lot. I saw it the added day on a adumbral floodplain at the abject of a abrupt barefaced forth our Congaree River.
Now ferns are an absorbing accumulation of plants from a actual age-old lineage, all of them vascularized, with affluence of water-conducting centralized “plumbing.” Ferns accept vascular tissue in accepted with the gymnosperms (cycads, pines, cedars, cypress, etc.) as able-bodied as the beginning plants (orchids, roses, sunflowers, sand-spurs, etc.). But, ferns don’t aftermath any flowers, or for that matter, fruits or seeds. Instead, they aftermath tiny spores which act as their breakdown units. In a fern, spores are about appear from the bulb out of specialized structures alleged “sporangia”, and afterwards amphibian about in the air for a while, the spores frequently achieve bottomward on the arena about and sprout. We are talking TINY here…with a resultant little bulb that botanists alarm a gametophyte. The gametophyte is a rather arid little affair that never attains a fern-like appearance, and generally stays absolutely beneath ground. The gametophyte is acutely important however, in the admirable appearance of all things fernish, back that’s area the gametes (egg and agent cells) are produced. Following fertilization, a absolutely new bulb anatomy arises from the gametophyte. This new bulb is what everybody recognizes as a “fern,” frequently developing a basis bottomward below, and with admirable blooming leaves aloft the ground. The new bulb is additionally area the spores appear from, and the aeon can activate again. Thus, there is an alternation of gamete-producing and spore-producing plants, aural the aforementioned species. (This aeon is referred to as “alternation of generations,” and it occurs in all the plants about us, not aloof ferns. As you ability expect, there are a few added analytical and somewhat complicated capacity complex in plants’ alternation of generations. This aspect of bulb reproduction is as alluring as it is biologically important, and yet for some reason, some of my acceptance tended to get a bit comatose and aloft during this accurate lecture.)
The sporophyte of our Abstruseness Bulb eventually produces a abbreviate rhizome, and anniversary year it will accelerate up a single, aphotic blooming frond, which does not aftermath any sporangia—it’s “sterile.” A additional blade is produced, however, and absorbed aloof beneath the clay line, which will buck several grape-like clusters of bare sporangia on its branches. This is the “fertile” frond, which will afford its spores by autumn. Then it dries up. The antiseptic frond, though, is evergreen, and will aftermost all winter. This breed has a cardinal of similar-looking relatives, but they all accept their antiseptic and abundant fronds alloyed calm able-bodied aloft the ground. ©JohnNelson2021
