Eleocharis quinqueflora

Growing form

Perennial, loosely cespitose herb.

Size

8–25 cm high.

Stem

The rhizome is long-stoloniferous. There is a 10 mm long brown winter bud at the apex of a rhizome stolon. The stem is about 0.5 mm thick, erect, with continuous pith, green and opaque.

Leaf

The stem is afoliate. There are two leaf sheaths at the base of the stem. The leaf sheaths are light yellow or brownish. The higher sheath does not have a lamina.

Flower

The inflorescence is a densely flowered, dark brown spike that is solitary at the summit of the stem. The spike is 5–10 mm long and three- to eight-flowered. The flowers are bisexual and axillary subtended by a pistillate scale. The pistillate scales are brown with a green mid-vein. The lowest pistillate scales are larger than the others, about 1/2 of the length of the achene and semi-amplexicaul. There are three stamens and a pistil with three stigmas in a flower. The perianth consists of 4–6 filamentous bristles.
