Edible and Non-edible Leaves.

— Mr. T. Grieve sent me from Moulamein edible and non-edible Red Gum leaves, on which I reported in the Agric. Gazette of June, 1899, p. 496, and at greater length, with the leaves of other trees, in this work, vol. v, p. 74.

I have drawn attention to this preference and repugnance of sheep and cattle for apparently the same leaves on various occasions, and believe it is worthy of the most careful investigation, but I have never been able to induce those who made reports to follow up the matter by careful collection of botanical material. Messrs. Baker and Smith, in their "Research on the Eucalypts," p. 75, in proposing a variety borealis, suggest that this may be one of the forms of the Red Gum whose leaves cattle cat, but as they say that this form does not present any morphological differences to the ordinary form, we are pretty much as we were so far as solution of this particular problem is concerned.
