Hymenophylloideae
''Hymenophyllum'' is a genus of ferns in the family Hymenophyllaceae. Its name means "membranous leaf", referring to the very thin translucent tissue of the fronds, which gives rise to the common name filmy fern for this and other thin-leaved ferns. The leaves are generally only one cell thick and lack stomata, making them vulnerable to desiccation. Consequently, they are found only in very humid areas, such as in moist forests and among sheltered rocks. They are small and easy to overlook.

Hymenophyllaceae
The Hymenophyllaceae, the filmy ferns and bristle ferns, are a family of two to nine genera (depending on classification system) and about 650 known species of ferns, with a subcosmopolitan distribution, but generally restricted to very damp places or to locations where they are wetted by spray from waterfalls or springs. A recent fossil find shows that ferns of Hymenophyllaceae have existed since at least the Upper Triassic. Description They often appear as very dark green or even black clumps and may be mistaken for a robust moss or liverwort. The rhizome is usually thin and wiry and the fronds variously pinnate with a single strand ("nerve") of vascular tissue. As in most ferns, young fronds have circinate vernation. In most species, the frond, apart from the vascular tissue, is only a single cell thick, and they do not have any stomata. The cuticle is also greatly reduced or absent, leaving filmy ferns very susceptible to desiccation where a reliable water supply is not ...

The Ferns Of Great Britain And Ireland
''The Ferns of Great Britain and Ireland'' was a book published in 1855 that featured 51 plates of nature printing by Henry Bradbury. Description The text was a scientific description of all the varieties of Ferns found in the British Isles. The author of this work was the botanist Thomas Moore, the editor was John Lindley. The book was released at a time of so-called "pteridomania" in Britain. Along with William Grosart Johnstone and Alexander Croall's ''Nature-Printed British Sea-Weeds'' (London, 1859–1860), the book featured Bradbury's innovative nature printing process. The publisher of the work was Bradbury and Evans. Bradbury patented the process after seeing the invention of Alois Auer - though the identity of its inventor grew to be a subject of debate. The technique was briefly in vogue, but did not persist in printing. Bradbury, along with Auer, believed the technique to be an enormous advance in printing. However, the plants and other subjects that could be su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hymenophyllum Australe
''Hymenophyllum australe'', commonly known as austral filmy fern, is a relatively large rupestral and epiphytic fern, indigenous to eastern Australia and New Zealand. It belongs to the unique ''Hymenophyllum'' genus ( filmy ferns), which are characterised by their thin membranous fronds that are seldom more than one cell thick, with the exception of regions over and around veins. ''Hymenophyllum australe'' is distinctive in that the fronds are typically thicker than other ''Hymenophyllum'' species, often being up to 2-3 cells thick.Garrett, M. (1986, December). "Fairies of the Fern World"'', Newsletter Number 35'', pp. 9. Retrieved from URL (https://www.verdigris.com.au/default.aspx?hid=310) ''Hymenophyllum australe'' is inconspicuous and will typically form matted patches together with mosses and liverworts. In Australia it takes on an epiphytic approach, commonly seen to clothe roots, trunks and rocks to form a dense mat of foliage; while in New Zealand it adopts a more rheophy ...
