These spores are produced in sporangia that develop on the leaves of the fern's sporophyte. The fern can also reproduce by the division of its rhizomes. On the underside of the blades, the sori (reproductive clusters) are round, discrete, and sunken. Their outline can be seen as raised dimples on the upper surface.
Sceptridium dissectum leaves are a light green during the spring and early summer, with the leaves becoming deciduous in late summer. The leaves usually turn a bronze color in late fall through winter. The grape like sporangia range from green to yellow. The petiole or stalk of the plant is green from top to bottom and glabrous as is the ...
Where the red fern grows: Why Eugene’s Delta Ponds turn red each year ... The red stuff adorning the 150-acre waterway site isn't algae or autumn leaves or dye, but an aquatic fern. Waterway ...
Fern spores are borne in sporangia which are usually clustered to form sori. The sporangia may be covered with a protective coating called an indusium. The arrangement of the sporangia is important in classification. [6] In monomorphic ferns, the fertile and sterile leaves look morphologically the same, and both are able to photosynthesize.
Azolla (mosquito fern, water fern, fairy moss) is a genus of seven species of aquatic ferns in the family Salviniaceae. They are extremely reduced in form and specialized, looking nothing like other typical ferns but more resembling the form of some mosses or even duckweeds .
Sceptridium biternatum, the southern grapefern or sparse-lobe grape fern , is a perennial fern in the family Ophioglossaceae, occurring in eastern North America. It occurs in "low woods, in hardwood and pine forests, in fields, and on roadsides." [2] Like other grape ferns, it depends on a mycorrhizal association in the soil to survive.
Propagating ferns from spores is a delightful process, but requires a fair bit of time. If you're looking for instant gratification, propagating from rhizome is an easier way—although plants may ...
Bracken (Pteridium) is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells (eggs and sperm). Brackens are noted for their large, highly divided leaves.
