9. 'Websteria' S. H. Wright, Bull. Torrey Bot. Club 14: 135. 1887

Herbs, perennial, not cespitose, stoloniferous, aquatic. Culms many-stemmed (branched), with stems in successive false whorls, terete; whorls terminating in clusters of leaves essentially indistinguishale from stems. Leaves sheaths, tubular, transparent, or scalelike when subtending stems; ligules absent; blades absent. Inflorescences terminal; spikelets 1; involucral bracts absent. Spikelets borne singly on branches arising from among leaves; scales 2, distichous, proximal empty, distal subtending flower. Flowers bisexual; perianth bristles 6-11, straight or curved, slightly longer than achene, retrorsely spinulose; stamens 3; styles persistent, linear, 2-fid, base slightly enlarged. Achenes biconvex

Towards a comprehensive survey of C₃ and C₄ photosynthetic pathways in Cyperaceae

Members of the family Cyperaceae were surveyed by original observation and from the literature to assess the distribution of C₃ and C₄ photosynthetic pathways in the family. All 107 genera were included in the current sample, with 91 genera assessed as consistently C₃ and 11 genera as C₄. The genera 'Abildgaardia', 'Cyperus', 'Eleocharis',' Fimbristylis', and 'Rhynchospora' are variable for this trait. Of the total number (1474) of specific (1406) and infraspecific (68) taxa sampled, 938 taxa (63%) are C₃, 527 taxa (36%) are C₄, and nine species of Eleocharis are debatably intermediate or variable in pathway. Some data suggesting further infrageneric variation in photosynthetic pathways are discussed. The "one cell distant criterion" accurately predicts C₄ pathway in sedges, except in Eleocharis. Distribution and variability of photosynthetic pathways in Eleocharis are discussed. Photosynthetic pathway was found to be a useful taxonomic marker in Cyperaceae, despite variability in this trait at various taxonomic levels and the apparently multiple origin of C₄ photosynthesis within the family. A checklist of 3395 records of C₃ and C₄ sedges is presented

20. 'Blysmopsis' Oteng-Yeboah

Herbs, perennial, cespitose, rhizomatous. Cu1ms terete or distally rounded-trigonous. Leaves basal; ligules present; blades flat. Inflorescences terminal, spicate; involucral bracts several, suberect, proximal leaflike, distal scalelike; spikelets 2-25 per spike. Spikelets: scales 2-5, lateral spikelets spirally arranged, each subtending flower, terminal spikelets pseudodistichous. Flowers bisexual; perianth bristles (0–)3-5(-6), barbed, shorter than achene; stamens 3; styles linear, 2-fid, base persistent. Achenes biconvex or piano-convex. x = 20

16. 'Remirea' Aublet

Herbs, perennial, not cespitose, rhizomatous. Culms solitary, trigonous, 12 cm or less, smooth. Leaves cauline; sheaths present; ligules absent; blades flat to V-shaped in cross section, prominently keeled on abaxial surface.

'Acacia beadleana' (Fabaceae: Mimosoideae), a New, Rare, Localised Species from Gibraltrar Range National Park, New South Wales

A new, rare species of phyllodinous 'Acacia' from granitic areas of the Gibraltar Range in northern New South Wales is described on the basis of phenetic analysis. Comparison of A. 'beadleana' with other morphologically similar species, and notes on its biology and ecology are presented. Conservation status for A. 'beadleana' is proposed
