Notes on Eucalyptus risdoni, hooker.

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.
