“…The peripheral reticulum of the Kranz cells in C. giganteus is conspicuous, as noted by Ueno et al (1988) in several C 4 species of Cyperaceae. However, in C. giganteus the peripheral reticulum does not form vesicles ("dumbbell") as described by Carolin et al (1977) for C. victoriensis C.B.…”

“…The convoluted thylakoids observed in C. giganteus have also been identified in other species of Cyperus (Carolin et al 1977, Ueno et al 1988. However, Estelita-Teixeira & Handro (1987) did not find convoluted thylakoids in their analysis of Cyperus species.…”

“…Various studies on the leaf anatomy of Cyperaceae species have shown four different types of Kranz anatomy in the C 4 species (Brown 1975, Carolin et al 1977, Ueno et al 1988, Bruhl & Perry 1995. They can be classified in the following groups, depending on whether they exhibit two or three sheaths: Chlorocyperoid (presence of discontinuous Kranz and mestome sheaths), Rhynchosporoid (presence of a Kranz sheath, in place of the mestome sheath, and a parenchymal sheath), Fimbristyloid (presence of Kranz, mestome and parenchymal sheaths) and Eleocharoid (presence of continuous Kranz and mestome sheaths).…”

“…The ultrastructural analysis of the different types of Kranz in Cyperaceae has revealed differences amongst the organelles, mainly between the chloroplasts of the Kranz sheath cells and those of the cells of the mesophyll (Carolin et al 1977, Ueno et al 1988, Estelita 1992. According to Estelita (1993), the ultrastructural characteristics of the Kranz cells, especially of their chloroplasts, can be used in the classification of the Cyperaceae.…”

-(Origin and structure of the Kranz tissue in bracts of Cyperus giganteus Vahl (Cyperaceae)). Cyperus giganteus shows Kranz anatomy of the clorocyperoid type or with two sheaths, one internal, adjacent to the vascular system and known as Kranz sheath, with thin-walled cells and a large number of organelles, mainly chloroplasts; and an external sheath, the mestome sheath or endodermis, the cells of which present thickened walls, are without chloroplasts and possess a suberin lamella, together with the casparian strip which are detected in early stages of differentiation. The development of the vascular bundles shows the Kranz sheath originating from the procambial as well as the mestome sheath. The chloroplasts of the Kranz cells are relatively larger, with convoluted thylakoids and a prominent peripheral reticulum, while the chloroplasts of the mesophyll cells are relatively smaller, with thylakoids forming grana and a sparse peripheral reticulum. These ultrastructural characteristics show similarities to those of other species of the genus Cyperus.Key words -bracts, clorocyperoid, Cyperaceae, Cyperus giganteus, Kranz RESUMO -(Origem e estrutura do tecido Kranz em brácteas de Cyperus giganteus Vahl (Cyperaceae)). Cyperus giganteus apresenta estrutura Kranz do tipo clorociperoide, ou seja, com duas bainhas: uma interna, adjacente ao sistema vascular ou bainha Kranz, que contém muitas organelas, principalmente cloroplastos; e uma bainha externa, a bainha mestoma ou endoderme com células de paredes espessadas, lamela de suberina, e que apresenta estrias de Caspary perceptíveis em estágios jovens de diferenciação. As bainhas Kranz e mestoma originam-se do cordão procâmbial. Os cloroplastos das células Kranz são relativamente maiores, com tilacóides convolutos e retículo periférico conspícuo; os cloroplastos das células do mesofilo são relativamente menores, com tilacóides formando granos e retículo periférico inconspícuo. Estas características corroboram àquelas de outras espécies do gênero Cyperus.
