a small, dry, thin-walled fruit, not splitting when ripe, and containing a single seed.

staminate flowers above the pistillate in the same spike.

attached secondary part; for example, a projection, hanging part, or supplement.

a fine bristle ending an organ (usually in grass flowers).

a slender projection, like the beak of a bird (e.g., persistent style base on fruit); also called a rostellum.

domed on two sides; also lenticular.

1. With two teeth; 2. Doubly toothed, where the marginal teeth themselves are toothed.

divided at the tip into two (usually equal) parts by a median cleft.

a modified and specialized leaf in the inflorescence, standing below partial peduncles, pedicels, or flowers.

growing in tight groups, the bases of the individual plants touching; also caespitose (which is preferred) or tufted.

with a rounded surface, like the outside of a bowl. Opposite: concave.

broadest at the middle with two equal rounded ends.

smooth and without hairs, scales or other trichomes

pistillate flowers above the staminate in the same spike.

general appearance of plant (e.g. erect or sprawling, herbaceous or woody).

indument type where individual hairs are visible.

the part of the plant that bears the flowers, including all its bracts, branches and flowers, but excluding unmodified leaves.

narrowly ovate and tapering to a point at the apex.

a 3-dimensional body that is circular in section and convex on both sides.

egg-shaped (2-dimensional) with the broadest part near the apex.

1. (2-dimensional) flat with a circular outline; 2. (more correctly) (3-dimensional) globose, in the shape of a sphere.

(in Cyperaceae) a membrane or sac enclosing the female flower and later the fruit = utricle.

1. female; 2. flower with only female organs.

with dense fine, short, soft hairs; downy.

persistent stylar base on fruit.

glume, the bract(s), usually occurring in pairs, at the base of a grass or sedge spikelet.

a tubular organ enveloping another organ; (in grasses or palms) the tubular part of the leaf enveloping the stem.

(in Cyperaceae) an aggregation of spikelets or spicoids, sometimes with the whole structure resembling a spikelet.

(in Cyperaceae and gramineae/poaceae) structure of two sterile bracts (the glumes) with a small axis and a number of florets (each consisting of lemma, palea and flower).

1. (of flowers) bearing stamens; 2. (of plants or flowers) male.

1. circular in cross-section (usually of a cylindrical structure lacking grooves or ridges); 2. sometimes taken to mean cylindrical and tapering gently at one end, but this is incorrect.

obtusely 3-angled.

ending abruptly in a more or less straight line, as if cut off.
