Buttonhead Pipewort is a small herb whose flower heads look like
Gomphrena. However, it is a wildflower found
in the Western Ghats. The genus name is derived from Ancient Greek εριον,
erion, meaning 'wool', and καυλός, caulos, meaning 'stalk'. The species are
mostly herbaceous perennial plants, though some are annual plants; they
resemble plants in the related families Cyperaceae (sedges) and Juncaceae
(rushes), and like them, have rather small, wind-pollinated flowers.
Flowering: September-October.
