5-1 mm wide at base, the basal ones 1-2 mm apart, retrorse-uncinate to spreading; fascicles 10 to 16 in number, polystichously disposed, suberect, sessile, subglobose-capitate to subcylindric in late anthesis, strobilate, densely rosulate, 2.
1 mm wide at base, the basal ones 3-10 mm apart, antrorse (upper ones) to retrorse (basal ones) uncinate; fascicles 7 to 11 in number, polystichously arranged, suberect, sessile, globose-capitate, strobilate, densely rosulate, 12-15 mm long (excluding the petals), 14-17 mm in diameter, 7 to 12-flowered; floral bracts broadly triangular-ovate, acuminate, slightly carinate toward the apex, equaling to slightly shorter than the sepals, but recurved and distinctly exposing them, green, nerved, inconspicuously and sparsely white-lepidote but soon glabrous, 10-13 x 8-10 mm, subdensely spinulose, spines irregularly curved, 0.
3-3 cm, margins inconspicuously and irregularly spinulose toward the apex to subentire; Inflorescence a simple spike, very densely strobilate
, narrowly ovate to cylindrical, erect, 8-15 x 3.
Quesnelia, with three species characterized by simple, densely strobilate
inflorescences, and pollen with psilate exine; and subgen.
Each solitary individual (oozooid) produces, by budding, a stolon which strobilates
into chains, between 25 and 75 aggregated individuals (blastozooids), depending on the oozooid size (Heron & Benham, 1985), for Thalia democratica.
