Lecanopteris sinuosa

''Lecanopteris sinuosa'' Wall. ex Hook. (Polypodiaceae) is a fern that belongs to the unique ant-fern genus, ''Lecanopteris''. This epiphytic plant has a mutualistic relationship with stingless shelter ants, which makes it a myrmecophyte.〔Gay, Honor. "Rhizome structure and evolution in the ant‐associated epiphytic fern Lecanopteris Reinw.(Polypodiaceae)." Botanical journal of the Linnean Society 113.2 (1993): 135-160.〕
The ant species associated with ''L. sinuosa'' belong within the genera ''Crematogaster'', ''Technomyrmex'' or ''Iridomyrmex''.〔Lok, A. F. S. L., and H. T. W. Tan. "Tuberous, Epiphytic, Rubiaceous myrmecophytes of Singapore." Nature in Singapore 2 (2009): 231-236.〕 The ants rear their larvae within the rhizome for protection, and in turn, ''L. sinuosa'' receives nutritional benefit from feces and other debris left behind by the plants.() It is also suggested that ''L. sinuosa'' benefits from increased protection from herbivory and increased spore dispersal.〔Gay, Honor. "Animal‐fed plants: an investigation into the uptake of ant‐derived nutrients by the far‐eastern epiphytic fern Lecanopteris Reinw.(Polypodiaceae)." Biological Journal of the Linnean Society 50.3 (1993): 221-233.〕
''L. sinuosa'' belongs in the subgenus ''Myrmecopteris'' (comprising four species total),〔Haufler, Christopher H., et al. "Systematics of the ant-fern genus Lecanopteris (Polypodiaceae): testing phylogenetic hypotheses with DNA sequences."Systematic Botany 28.2 (2003): 217-227.〕 which is characterized by ferns that have peltate scales and sori that are deeply immersed on the pinnae.()
== Rhizome morphology ==

The unique rhizome structure of ''L. sinuosa'' allows it to maintain a mutualistic relationship with ants. As the plant is young, the rhizome is solid (without cavities), but as it matures, the thin walled parenchyma cells begin to hollow (). These cells become infused with phlopaphene (a deep brown strengthening substance), which causes the rhizome to appear rock-like.
