Huperzia phlegmaria
''Huperzia phlegmaria'' (commonly known as either coarse tassel fern,〔 or common tassel fern〔) is an epiphytic〔Rusea G., Claysius K., Runi S., Joanes U., Haja Maideen K.M., Latiff A. (2009) Ecology and distribution of ''Lycopodiaceae'' Mirbel in Malaysia, Blumea vol:54, pg:269-271〕 species of tassel fern native to rainforests in Madagascar, some islands in the Indian Ocean, Asia, Australasia and many Pacific Islands. ''Huperzia phlegmaria'' is commonly found in moist forests and rainforsests at high altitudes; in and amongst mosses and other epiphytes. Members of the order Lycopodiales are commonly referred to as clubmosses.
==Description==
A vascular species of the phylum Lycopodiophyta, ''Huperzia phlegmaria'' resembles many species of moss. The specialised fluid conducting tissues of vascualr plants distinguish Lycophytes from the more basal Bryophytes (Mosses and Liverworts). The diploid ''sporophyte'' stage of the life cycle of Lycophytes is dominant. Sporophytes produce tetrahedral spores of 37 x 35μm, off-white in colour, with angles never exceeding 130°.〔Devi Y.S., Singh P.K. (2011) Additional Notes on Spore Morphology of Two ''Huperzia'' (Lycopodiaceae) Species and Systematic Significance, Research Journal of Botany vol:6, pg:78-86〕
''Huperzia phlegmaria'' is a variable species and plants from different regions can vary widely in stature.〔Wikström N., Kendrick P., Chase M. (1999) Epiphytism and terrestrialisation in tropical ''Huperzia'' (Lycopodiaceae), Plant Systematics and Evolution vol:218, pg:221-243〕 They can be identified by having petiolate sterile microphylls and small fertile microphylls on thin branching strobili.
Individuals of ''Huperzia phlegmaria'' have true root systems. Their elongated aerial stems hang from host trees (up to 80 cm long.〔 The spirally arranged leaves are lanceolate (lance like), narrow and rounded at the base. They become even narrower at the extreme base, where the sporangia are located in the fertile zone of the stem. Leaves of ''Huperzia phlegmaria'' are coriaceous (resemble leather). The leaves differ in morphology in the fertile zone, making distinction between the zones easy. Leaves in the fertile zone are known as sporophylls. Sporophylls are club shaped - hence the common name "clubmoss". Homosporous spores are produced in axils.
