Filgueirasia Cannavieira

''Filgueirasia'' is a genus of Brazilian bamboo in the grass family.

Members of the genus were originally published as species of '' Apoclada'' and were classified in that genus for many years.McClure, F. 1973. Genera of Bamboos Native to the New World(Gramineae: Bambusoideae). Smithsonian Contributions to Botany 9: 1-148.Judziewicz, E.J., L.G. Clark, X. Londono, & M.J. Stein. 1999. American Bamboos. Smithsonian Institution Press, Washington DCGuala, G.F. 1992. All About ''Apoclada'' (Poaceae: Bambusoideae) a monograph of the genus. Thesis presented to the Graduate School of the University of Florida.

Over time though, with revised concepts of morphological interpretation in the bamboos and the accumulation of strong molecular evidenceGuala, G.F., D. Bogler, J. Sadle and J. Francisco Ortega 2000. Molecular Evidence for polyphyly in the genus ''Apoclada'' (Poaceae: Bambusoideae). Bamboo Science and Culture 14:(1): 15-20. it became clear that the two species formerly known as ''A. arenicola'', and ''A. cannavieira'' are actually unrelated to ''A. simplex'' and are correctly placed in their own genus ''Filgueirasia''.Guala, G.F. 2003. A new genus of bamboos from the cerrados of Brazil. Bamboo Science and Culture, Journal of the American Bamboo Society 17(1): 1-3

The genus was named after Dr. Tarciso Filgueiras who has been an icon of scholarly research on the grasses of Brazil, especially those of the cerrado region, for decades. There is a photograph of him in a patch of ''F. arenicola'' on the cover of the journal in which the genus was published - cited above and linked below.

Both species are unusual in many respects. They display the unique (or nearly so depending on interpretation) condition in the bamboos of having the ability to give rise to branches from multiple equal primary branch buds at their nodes. They are also some of the most drought tolerant of the bamboos and are well adapted to fire. They serve as forage for cattle and wildlife, especially in the dry season when the above ground parts of many other grasses are dead.Guala, G.F. 2001. A brief note on the forage value of ''Apoclada''. Bamboo Science and Culture 15(1): 48 Although both species are highly adapted to the cerrado biome, they have separate ranges and different habitat requirements including soils and climate.Guala, G.F. 2000. Spatial habitat characterization and predictions for two endemic sister species of bamboo on the cerrados of central Brazil. Bamboo Science and Culture 14(1): 21-27
