One explanation for greater anther extrusion under cool-moist conditions is the variability in lodicules size.
In the PACC clade, above the point of divergence of Aristida from other members of the clade, the apical membranous portion is reduced or absent, giving the lodicule a truncate form and fleshy texture.
That the posterior lodicule develops above the anterior lodicules, rather than below them, as would be the case if they were all part of the same whorl, and that the posterior lodicule is sometimes suppressed, favors an interpretation that they are derived from stipules, leaves, or branches (Clifford, 1987).
Notes on some grasses XIX: systematic significance of microhairs on lodicules epidermis.
In turn, each floret consists of a pair of glumes, a lemma, a palea, a pair of lodicules, three stamens, and a pistil.
Four patterns of association were detected among the eight glume and grain qualitative traits: (i) aleurone (Gr-1) and grain colors (Gr-2); (ii) spiculations of inner lateral nerves (Gr-5) and length of lodicules (Gr-6); (iii) glume hairiness (Gl-1) and rachilla hair type (Gr-4) were plotted in pairs in close proximity; and (iv) lemma color (Gl-2) and lemma base type (Gr-3).
Tyto has medium-long and medium-wide kernels that have clasping lodicules with an incomplete horseshoe-shaped lemma base.
The kernels have colorless aleurones, medium long rachillas with short rachilla hairs, clasping lodicules, and horseshoe basal markings.
Its kernels have medium length and width with clasping lodicules, and horseshoe shape of basal markings.
Wheat florets have two lodicules at the base of the ovary, which function to open the floret at anthesis.
