However, the presence of ferulate in their primary walls showed they were commelinid monocotyledons and they have now been reclassified as the commelinid family Dasypogonaceae (Rudall and Caddick 1994;Rudall and Chase 1996), although the order in which they should be placed is still uncertain (APG II 2003;Chase et al 2006;Fig. 4).…”

The distribution of ester-linked ferulic acid in the cell walls of angiosperms

2009

Ester-linked ferulic acid occurs in the cell walls of two major groups of angiosperms, the commelinid monocotyledons and the 'core' Caryophyllales, at concentrations [3.5 mg g -1 cell walls, and has been detected in primary cell walls by its autofluorescence using ultraviolet fluorescence microscopy. Both of these groups are resolved as monophyletic clades in phylogenetic trees constructed using gene sequences. In the primary cell walls of the commelinid monocotyledons, including the grasses (family Poaceae), the ferulic acid is ester-linked to the non-cellulosic polysaccharide glucuronoarabinoxylan. In contrast, in the 'core' Caryophyllales, the ferulic acid is ester-linked to the side chain arabinans and galactans of the pectic polysaccharide rhamnogalacturonan-1, at least in the family Amaranthaceae. In the walls of both angiosperm groups, a range of dehydrodiferulates have also been found. These are formed oxidatively via radical coupling and result in the cross linking of the polysaccharides to which they are attached. Much lower concentrations of ester-linked ferulic acid have been found in cell walls isolated from other angiosperms, although physiological stress conditions may cause increases in these concentrations. The polysaccharides to which the ferulic acid is attached to in the cell walls of these other angiosperms is unknown.

“…But, in the lower epiderma of I. pseudocaucasica , crystals granules were very rare. Styloids (prismatic crystals or pseudoraphides) were generally seen either in bundle sheath cells or mesophyll cells in the surrounding of the bundle sheaths of monocot leaves by Rudall and Chase (). Also, styloids were significant properties of some families, notably of Iridaceae of Asparagales.…”

Iris L. is one of the important genus of family Iridaceae, consist of 56 taxa naturally occurred in Turkey. The similarities and variations in the subgenus overlapping the taxonomic positions of the species in the subgenera and needs anatomical assessment especially by microscopic techniques. In this study, the taxonomic significance of leaf anatomical characters of 10 Iris subgenus Scorpiris taxa were studied in detail and the relationship among these taxa were evaluated using microscopy techniques. Fresh leaf samples of species were fixed in 70% alcohol solution for anatomical observation under microscope. Eleven different micromorphological features were statistically analyzed to delimit the species in subgenus. Based on morphological and anatomical similarities, we studied relationships among; (1) ssp. turcica, ssp. caucasica, I. nezahatiae and I. pseudocaucasica; (2) correlation between ssp. turcica and ssp. caucasica; (3) association of I. galatica, I. persica, ssp. margaretiae and ssp. stenophylla with each other; (4) relationship between ssp. stenophylla and ssp. margaretiae; and (5) relevance between I. aucheri and I. peshmeniana. Moreover, the taxonomy of subgenus Scorpiris has been discussed in detail with novel and diagnostic features based on micromorphological physiognomies. We found that four species in this study are endemic to Turkey, while seven are critically endangered geophytes in the country. The leaf anatomical characteristics of 10 taxa were divided into three groups. Main aim of this research was to study the taxonomy of the complex subgenus Scorpiris through microscopic techniques.

The new species Thysanotus racemoides Sirisena, T.D.Macfarl. & Conran, from South Australia and western Victoria, is described and distinguished from the previously conspecific T. juncifolius (Salisb.) J.H.Willis & Court, by the presence of sessile subterminal umbels and relatively longer anthers and perianth segments. The revised distribution of T. juncifolius is New South Wales and eastern Victoria. Descriptions, photographic plates and a map are provided for the new species and T. juncifolius. The key in the Flora of Australia is amended to accommodate the new species.
