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.
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]
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 ...

The spore-bearing stems persist after the sterile fronds are killed by frost, until the next season. The spores must develop within a few weeks or fail. The Osmundastrum cinnamomeum fern forms huge clonal colonies in ...
In botany, a sporophyll is a leaf that bears sporangia. Both microphylls and megaphylls can be sporophylls. In heterosporous plants, sporophylls (whether they are microphylls or megaphylls) bear either megasporangia and thus are called megasporophylls, or microsporangia and are called microsporophylls. The overlap of the prefixes and roots ...
