Bambusina borreri (Ralfs) Cleve var. majus C.B.Araújo, C.E.M.Bicudo & S.Melo , comb. nov.
Gymnozyga moniliforms Ehrenberg var. majus Raciborski , Flora, Jena 81: 31. 1985.
( Figs. 5 View Figs A-B)
Cell 1.6 times greater in length than width, 35-44 × 21-29 μm, 12-16 μm broad at the apex and 20-24 μm broad at the isthmus. Semicells pyramidal-truncated; parallel lateral margins, strongly concave at the base; straight, truncated apex with 2 tiny angular spines; shallow median constriction; open median sinus; hyaline cell wall; axial chloroplast.
Material examined: BRAZIL, AMAPÁ, Macapá, Curralinho Lake , 02.VI.2007, C.B. Araújo (SP469217), 03.VII.2007, C.B. Araújo (SP469218), 15.IV.2008, C.B. Araújo (SP469226), 13.V.2008, C.B. Araújo (SP469227), 15.VII.2008, C.B. Araújo (SP469228) .
Comments: Raciborski (1895) reported the present variety as Gymnozyga moniliforms var. majus Raciborski. Later on, based on material collected nearby in the Arapiuns and the Tapajós rivers, Pará state, Scott et al. (1965) proposed a new combination by reclassified this species from Gymnozyga to Bambusina : Bambusina brebissonii Kützing var. majus (Raciborski) Croasdale. Although B. brebissonii is the type species of Bambusina , it is currently considered as synonymous by some authors and consequently reclassified to B. borreri . Thus, the present report proposes the new combination Bambusina borreri var. majus , and the combination in Scott et al. (1965) should be considered synonymous. This variety differs from the species type based on the presence of straight truncated apices with two tiny angular spines.
Distribution in Brazil: Pará state ( Scott et al. 1965, Förster 1969).
