years, and where very hard frosts occur at intervals from late autumn to early 
spring; the summer season being variable, but usually warm and genial. Estimated

Probable limit of vigorous resistance to cold for seedlings and young saplings, 
between 12° and 18° F.

NATURAL HABITAT, DESCRIPTION, AND USES. 
In earlier botanical literature this name was applied to at least six distinct 
eucalypts, all but one of which have since been separately named and defined. The 
very tall trees mentioned by Baron F. von Mueller in bis Eucalyptograpliia and 
Select Extra-Tropical Plants were soon given separate specific rank as E. 
regnans by Mueller himself. Three Australian members of the original group 
were a good many years ago named respectively E. dives , E. numeiosa , and E. 
radiata , and a Tasmanian member E. nitida. The name E. amygdalina remains, 
and is restricted to certain eucalypts widely distributed in Tasmania but nowhere 
found on the mainland. The difficulties of the botanist have by tins procedure 
been greatly reduced; but they have not been ended. For what we actually find 
in Tasmania in this connection is not a narrow and rigidly defined type, but a 
group or series in which we have to reckon with a large amount of variation. 
Botanists have endeavoured to divide the series into two sections and to give each 
section specific rank. Trees with wider leaves, slightly larger fruits, and some 
amount of dead bark clinging to their stems are assigned to E. amygdalina. liees 
with extremely narrow leaves, smaller fruits, and smooth-barked stems are gi\ en 
the name E. linearis., after the botanist Dehnhardt who so named^a cultivated 
specimen in Italy. But between these selected types are intermediate forms liat 
obviously link lie .wo foge.h.v, M.id.n. view of the proto “ 
page 169 Vol. i. of the Critical Revision, where he says:- The idea becomes 
stronger with me that E. linearis Dehnh. may prove to be a perfectly smoo i 
barked form of E. amygdalina, with unusually thin, linear leaves. so, is oim 
of E. amygdalina might be named var. linearis. Rodway, m a pm ate let 
dated April 22nd, 1926, presents a similar view in the fo 1 owing e en m 
emphatic wordsWe recognise two forms of E. amygdalina name^Black 
Peppermint (E. amygdalina Lab.) and White P cppeimm . 
These run absolutely into one another. Both the forms produce a strong wood of 
great resistance to decay.”
