Abstract:
Mature leaves of eight species of Xyris were prepared by standard methods for electron transmission microscopy. Wartlike intercellular pectic protuberances were observed on the surface of inner periclinal walls of epidermal cells in Xyris obcordata, Xyris hymenachne, and Xyris pterygoblephara. In the latter, the protuberances also occur on the surface of parenchymatic mesophyll cells; they frequently project into intercellular spaces and may connect opposing cells. For the genus Xyris, the intercellular pectic protuberances may be considered taxonomically significant at the species level. Keyw

Abstract:
A systematic study of the Australian species of Xyris section Xyris is presented. Seven species are recognised, of which Xyris cheumatophila A.N. Doust & B.J. Conn is described for the first time. All recognised taxa are provided with descriptions (including illustrations), distribution information (including maps), habitat descriptions, nomenclatural and other relevant notes. Lectotypes are here designated for all previously described Australian species of section Xyris which are accepted by us. An iconotype of the name of X. indica (the type of the genus) is here chosen.

Abstract:
A new species of Xyris from the Southern and Southeastern regions of Brazil is described herewith. Xyris cervii belongs to Xyris section Nematopus, which is characterized by having basal to central placentation. Xyris cervii is morphologically similar to X. tortula, but differs by its deliquescent sheath with long hairs at the margin sheath, in addition to lanceolate and sub-equilateral, lateral sepals. A description, illustrations, geographic distribution and taxonomic comments are also provided.

Abstract:
This study examined the possibilities of enhancing methane yield from anaerobic digestion of Xyris capensis and duck wastes based on improved feeding composition and the C/N ratio. Batch anaerobic digestion of Xyris capensis and duck wastes was conducted at mesophilic temperature (37 ± 2 °C) with the mixing ratios of 100:0, 75:25, 50:50, 25:75, and 0:100% of duck wastes: Xyris capensis. The highest methane yield of 301.17 mL CH4/ gVSadded was recorded when the mixing ratio of 50:50% (duck wastes: Xyris capensis) and C/N ratio of 19.26 was digested.

Abstract:
Three endemic species of Xyris (Xyridaceae, Poales) are currently recognized in New Caledonia. A recent multivariate analysis of 18 morphological characters based on 129 specimens of Xyris from New Caledonia, supported by 10 anatomical and micromorphological observations, suggested that three species should be recognized in the New Caledonian archipelago. However, the three published names did not correspond to the three entities identified via the multivariate analyses. The results showed that Xyris neocaledonia Rendle was morphologically distinct but requires lectotypification, Xyris guillau

This study investigates the effects of NaOH pretreatment on the microstructural distribution and biomethane released from Xyris capensis. Xyris capensis was pretreated with NaOH using 1, 2, 3, 4, and 5% w/w concentrations for 60, 45, 30, 20, and 15 min of exposure time, respectively, at a 90 °C autoclave temperature. The impacts of the pretreatment technique on microstructural arrangement, crystallinity, and functional groups were examined with a scanning electron microscope (SEM), X-ray diffraction, and Fourier transform infrared (FTIR), respectively.
