Etymology
Baumea named after Antoine Baume (1728–1804), a French chemist and inventor. Juncea from the Latin 'juncus' meaning rush-like, alluding to its appearance and habit.

Plant description
Slender perennial sedge with smooth, terete, stems to 100 cm high and 1 mm thick and 2- or 3-noded. Leaves all reduced to mucronate sheaths. Flower in small panicle; spike-like to 8 cm long with few, reddish-brown, densely crowded spikelets. Flowering September to April. Fruits are short golden brown heads at the tip of the stem. Seeds are reddish-black elliptical nut to 4mm long and 3mm wide, with a pitted surface. Seed embryo type is capitate.
Seed collection and propagation
Collect seeds between December and June. Collect whole fruiting heads that are brown, containing dark hard seeds. Not all heads will contain seeds. Place the heads in a tray and leave to dry for one to two weeks. Then rub the heads with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. This species is generally difficult to germinate, it has morphophysiological dormancy and complex germination requirements.
