“…Recent studies reportedly subdivided this family into two clades, which are represented by the subfamilies Mapanioideae and Cyperoideae (Simpson et al 2007;Muasya et al 2009aMuasya et al , 2009b. Among Cyperoideae, the tribe Cypereae may be subdivided into two subclades (Larridon et al 2013): one -"Ficinia Clade", with about 160 species -represents the species of southern Africa, the majority of these bearing spirally arranged glumes; the other -"Cyperus Clade", with about 950 species -represents the Pantropical species, most of them with distichous glumes.…”

Cyperus is a Pantropical genus and the second richest in species in Cyperaceae. It encompasses about 550 species worldwide, with about 100 of these occurring in Brazil. Studies on the taxonomy of this genus are scarce and punctual in Brazil. In this study, the occurrence of species was surveyed through 27 collecting expeditions across different regions in the state of Rio Grande do Norte and analyzis of specimens of several herbaria. Twenty four species of Cyperus were identified, including six new occurrences and one new species, here described, but that will be properly published in other work. This study includes a dichotomous key for the identification of the species, as well as illustrations, descriptions, taxonomic comments and geographical distribution.

“…Muasya (2009) reported that in this genus, those belonging to the C 3 photosynthetic pathways tend to possess spikelets arranged in digitate clusters. This constitutes a form of morphological characters used to distinguish C 3 from C 4 taxa whose spikelets are usually spicately arranged.…”

Inflorescence and floral morphological characters in twelve species of Cyperus -a genus known to have C 3 and C 4 photosynthetic species -were investigated in order to check their usefulness in delimiting species into photosynthetic groups. Plant species were collected from different locations within Southwestern Nigeria. Qualitative characters were noted and recorded while some quantitative characters were measured with metric ruler to the nearest centimeter and others were counted. The results revealed that compound umbellate inflorescence, digitately arranged spikelets and short spikelets not over 1cm long are characters that separate C. difformis and C. haspan which are C 3 species, while the rest with simple umbellate inflorescence, spicate spikelets and spikelet length over 1cm are C 4 species. Cyperus dilatatus, a species without a previous record of photosynthetic grouping, is hereby grouped as a C 4 species since it shared characters with the rest C 4 species. From this study, a combination of characters was identified, which can possibly be used along with known data from other sources in the grouping of Cyperus species as either C 3 or C 4 species. Data on C. dilatatus also showed that it possibly belong to C 4 species. This is probably the first known report on photosynthetic grouping of this species.

J. Dorr SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTIONEmphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: In these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institutions throughout the world.Manuscripts submitted for series publication are received by the Smithsonian Institution Scholarly Press from authors with direct affiliation with the various Smithsonian museums or bureaus and are subject to peer review and review for compliance with manuscript preparation guidelines. General requirements for manuscript preparation are on the inside back cover of printed volumes.
