(Male Fern), a phytogeographically important discovery in northern Saskatchewan.
Plants or plant parts belonging to this category were Asteracantha longifolia, Alternanthera sessilis, Centella asiatica, Enydra fluctuans, Chenopodium album, Dryopteris filix-mas
, Lathyrus sativus, Tamarindus indica (leaves only, fruits are edible and consumed regularly), Glinus oppositifolius, Oxalis corniculata, Bacopa monnieri, and Cissus trifoliata.
The 1,200 specimens of feathery Dryopteris filix-mas
are nourished by a mixture of bacteria, nutrients and rainwater, which can be adjusted in response to climate and light.
Include a few evergreen varieties such as the glossy- leaved hart's-tongue fern and the male fern, or Dryopteris filix-mas
, which has coarse-looking fronds and suits dry and impoverished soil.
Plagiogyria euphlebia produces an irregular nucleus and obvious nuclear evaginations in the maturing egg, which resemble the derived ferns Pteridium aquilinum (Bell and Miilethaler, 1962b; Bell, 1972; Bell and Duckett, 1976; Bell, 1983), Dryopteris filix-mas
Our common fern, Dryopteris filix-mas
, although rather coarse in appearance, is exceptionally hardy and looks particularly good growing from a rocky crevice while the evergreen Asplenium adiantum-nigrum is a fine plant all year round.
flabellulatum possesses distinctive evaginations, similar to those in other leptosporangiate ferns so far investigated, including Pteridium aquilinum (Bell and Mulethaler, 1962b; Bell and Duckett, 1976), Dryopteris filix-mas
