Abstract

The limits that shall be assigned to this species is a
puzzle to the student. Hooker described the plant from
material gathered at Risdon. He figured it in his Flora
Tasmaniae. It is abundant on the dry hills from Risdon
to Rokeby, besides elsewhere, exactly in the form of his
description. In this type-form the leaves are opposite,
sessile, connate, and so covered with pale wax as to be
of a pale glaucous colour. The flowers and fruit differ
in no detail from those of Peppermint (E. amygdalina
Lab), except that they are larger. The fruit is pyriform
or turbinate, even on the same tree, and ranges in diameter
from about 9 m.m. to 13 m.m. In E. amygdalina
the fruit is nearly always turbinate, and ranges from 5
m.m. to 7 m.m. diameter.
The leaves of the typical E. Risdoni are arranged in
opposite pairs, and each pair is broadly connate across
the stem.
