'''''Gleichenia''''' is a [[genus]] of [[fern]]s.<ref name=NSW>{{cite web |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=gn&name=Gleichenia |title=Genus ''Gleichenia'' |accessdate=2009-01-26 |author=|work= PlantNET - New South Wales Flora Online |publisher=Royal Botanic Gardens & Domain Trust, Sydney Australia}}</ref> {{Inc| Gleichenia (W. F. Von Gleichen, 1717-1783). Gleicheniaceae. Ferns mainly from the tropical and south temperate zones, growing naturally in dense thickets; one species has recently been found in Louisiana, D. flexuosa. The family is characterized by dorsal sori composed of a few nearly sessile sporangia; each sporangium is surrounded by a broad transverse ring, and opens vertically. The most striking thing about the family is the growth of the lvs. The lvs. of many of the species are perennial and show an indeterminate growth. During the growing season, the end of the If. will keep unrolling after the usual manner of ferns. During the resting season this tip rests, but resumes its growth the next season. The lvs. of some species may thus become over 100 ft. in length. The species after the third (aa) are often catalogued under Mertensia, a name which, because used for a genus of flowers, must give way to Dicranopteris if they are separated and placed in a distinct genus, where they probably belong. {{SCH}} }} ==Cultivation== {{edit-cult}}<!--- Type cultivation info below this line, then delete this entire line --> ===Propagation=== {{edit-prop}}<!--- Type propagation info below this line, then delete this entire line --> ===Pests and diseases=== {{edit-pests}}<!--- Type pest/disease info below this line, then delete this entire line --> ==Species== Species include<ref name=NSW/>: * ''[[Gleichenia abscida]]''<small> Rodway</small> * ''[[Gleichenia alpina]]''<small> R.Br.</small> * ''[[Gleichenia dicarpa]]''<small> R.Br.</small> – Pouched Coral Fern, Tangle Fern * ''[[Gleichenia mendellii (G.Schneid.)]]''<small> S.B.Andrews</small> * ''[[Gleichenia microphylla]]''<small> R.Br.</small> – Scrambling Coral Fern, Parasol Fern, Umbrella Fern, * ''[[Gleichenia rupestris]]''<small> R.Br.</small> ==Gallery== {{photo-sources}}<!-- remove this line if there are already 3 or more photos in the gallery --> <gallery> Image:Upload.png| photo 1 Image:Upload.png| photo 2 Image:Upload.png| photo 3 </gallery> ==References== *[[Standard Cyclopedia of Horticulture]], by L.
