inserted between the four ovary lobes
is a large worldwide family and is reasonably common in Tasmania,
with both native and introduced species.
The native species include shrubs, undershrubs and herbs, and occur
in a wide range of habitats. The leaves are opposite or, in Westringia,
whorled. They are often aromatic - the family includes basil,
oregano, mint, sage, thyme and many other
culinary herbs. The flowers have fused, asymmetrical corollas (often
with an upper lip of two lobes and a lower lip with three lobes). The
calyx is typically a short, lobed tube that is persistent around the
developing fruit, which are four nutlets.
