''Apoclada'' is a genus of Brazilian bamboo in the grass family).〔McClure, F. A. & L.B. Smith. 1967. Gramíneas – Suplemento. Bambúseas. 1(GRAM–Supl.): 1–78. In P. R. Reitz (ed.) Flora Ilustrada Catarinense. Herbário "Barbosa Rodrigues", Itajaí, Brasil〕 The only known species is ''Apoclada simplex,'' found in the forests of southeastern Brazil (States of Santa Catarina, Paraná, and São Paulo).〔〔Renvoize, S. A. 1988. Hatschbach's Paraná Grass. 1–76. Royal Botanic Gardens, Kew〕 The genus was for many years thought to contain four species (''Apoclada cannavieira'', ''A. arenicola'', ''A. diversa'' & ''A. simplex'')〔McClure, F. 1973. Genera of Bamboos Native to the New World(Gramineae: Bambusoideae). Smithsonian Contributions to Botany 9: 1–148.〕 Upon further examination and fieldwork at the collection locality, the single piece of material at the US National Herbarium from which ''A. diversa'' had been described, was found to be merely a deformed stem of ''A. simplex''〔Guala, G.F. 1992. All About ''Apoclada'' (Poaceae: Bambusoideae) a monograph of the genus. Thesis presented to the Graduate School of the University of Florida.〕〔Guala, G.F. 1995 A cladistic analysis and revision of the genus ''Apoclada'' (Poaceae:Bambusoideae). Systematic Botany 20(3): 207–223〕 Later, with revised concepts of morphological interpretation in the bamboos and strong molecular evidence〔Guala, 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'' which are endemic to the cerrado of central Brazil 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 17(1): 1–3〕 The stems of this bamboo grow to more than 13 m tall although half that is more common. Like all bamboos, the upright stems (also called culms) grow from horizontal underground stems called rhizomes. In ''A. simplex'' these rhizomes can be more than 40 cm long, thus although this species is technically a clumping type of bamboo, groves of it often appear much like those of the Asian running bamboos because of the long distance between culms. The culms are light to dark green or sometimes reddish, and about 1.9–4 cm in diameter with internodes every 7–38 cm. The foliage leaf blades are long and thin, 1.3–16.4 cm long and 2–7 mm wide. ;formerly included〔 see ''Filgueirasia'' * ''Apoclada arenicola - Filgueirasia arenicola'' * ''Apoclada cannavieira - Filgueirasia cannavieira'' ==See also== *List of Poaceae genera 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Apoclada」の詳細全文を読む スポンサード リンク
