Plectranthus omissus

Status: Endangered on the EPBC Act list

Plectranthus omissus, Family Lamiaceae, is a multi-stemmed upright herb to 1 m tall that is
unscented or slightly scented. Leaves are opposite, oval-shaped, slightly fleshy, to 8 cm long,
velvety hairy, with 17Ð19 teeth on each margin. Inflorescences are in terminal spikes to 35 cm
with clusters (verticillasters) of 14Ð16 small, two-lipped, mauve flowers, 8.5Ð8.8 mm long.
Plectranthus omissus is closely related to P. argentatus, P. graniticola and P. torrenticola but
is distinguished by the corolla tube (fused tubular part of the petals), which is shorter (4.8Ð
5 mm long) and has sessile (not stalked) glands as well as hairs (Forster, 1992; Queensland
Herbarium, 2008).
