|Extending rhizomes sideways,
Eleocharis equisetiformis, a perennial herb of a height of
30-60cm, grow sparsely in sandy soil wetlands. The stems,
cylindrical, about 2mm in diameter, have ridges on them, and they
look like vertical lines; the stem tips bear spicules on them, and
the stigma is cleft in two. There are 0 to 4 needle-shaped perianth
segments. This species rarely occurs, and the Ministry of the
Environment designates it as a VU. Bloom time: July- October.
