The spores repel water and have been used as a powder on skin rashes and even on baby bottoms, and to treat wounds. Spores have been used historically as coating for pills, and in the Americas and Europe as fabric dyes. Spores are also highly flammable due to their high content of oil.
Zealandia pustulata is a species of fern native to eastern Australia and New Zealand. [2] It is commonly referred to as 'kangaroo fern' or 'kangaroo paw fern' as its native range includes Australia and the shape of its mature foliage tends to resemble the shape of a kangaroo's foot.
Like other ferns, members of the Marsileaceae produce spores, but not seeds when they reproduce. Unlike other ferns, the spores in this family are produced inside sporocarps. These are hairy, short-stalked, bean-shaped structures usually 3 to 8 mm in diameter [1] with a hardened outer covering. This outer covering is tough and resistant to ...
Platycerium is a genus of about 18 fern species in the polypod family, Polypodiaceae. Ferns in this genus are widely known as staghorn or elkhorn ferns due to their uniquely shaped fronds. This genus is epiphytic and is native to tropical and temperate areas of South America, Africa, Southeast Asia, Australia, and New Guinea. [1]
The first is by size, the rattle snake fern can be found up to two feet tall compared to the cut-leaf fern that can be found up to a foot tall. Second the petiole or stalk for a cut-leaf fern is light green while the rattlesnake fern’s petiole is pink at the base. Sceptridium dissectum (Spreng.) Lyon was known as Botrychium dissectum Spreng.
Psilotum nudum, the whisk fern, [3] is a fernlike plant. Like the other species in the order Psilotales, it lacks roots. [4]Its name, Psilotum nudum, means "bare naked" in Latin, because it lacks (or seems to lack) most of the organs of typical vascular plants, as a result of evolutionary reduction.
The leaves are glossy, broad and pinnate, the pinnae being dark green, leathery, alternate and widely spaced. The outer fronds arch over sideways but the central ones are nearly straight. Some of the larger fronds bear sporangia (reproductive organs) on the upper five to eight pairs of pinnae. These are brick red and give the pinnae a felted ...
Salviniales are all aquatic and differ from all other ferns in being heterosporous, meaning that they produce two different types of spore (megaspores and microspores) that develop into two different types of gametophyte (female and male gametophytes, respectively), and in that their gametophytes are endosporic, meaning that they never grow outside the spore wall and cannot become larger than ...
