2. Var. radiata, containing the tree usually known as " River 
White Gum." 
Sucker or seedling haves broadish. 
3. Variety latifolia ( nobis), comprising some of the broad - 
leaved forms. 
There are other forms, at present placed under amygdalina, 
but as our specimens or observations in regard to them are 
incomplete, we prefer to postpone consideration of them. 
1. Typical E. amygdalina. 
Introductory. — In the case of such a protean species as E. 
amygdalina, it may be useful, and it is certainly interesting, to 
note what the definition of the species really was, as by different 
authors the description has been modified very considerably. 
The original specimen described by Labillardiere came from 
Tasmania. The following is Don's translation of the species 
description given in DC. Prod. iii. 219 : — 
" Lid hemispherical, nearly mutic, shorter than the cup; 
peduncles axillary and lateral, nearly terete, length of the petioles; 
umbels 6-8 flowered, nearly capitate; leaves linear-lanceolate, 
attenuated at the base, and acuminately mucronate at the apex. 
Leaves 3 inches long, and 3 lines broad, some unequal at the base, 
and some equal. Petioles and peduncles 3 lines long. Fruit 
globose, size of a grain of pepper." 
Vernacular names. — Peppermint or Messmate are the most 
widely used names, and they are perhaps indiscriminately 
employed. Perhaps the former name is more prevalent as far 
north as Mittagong and the Blue Mountains, and the latter in 
New England, but the two names are often employed in the same 
district for the same tree. Some other local names will be found 
under Range. 
Bark. — This is the least variable characteristic; it is sub- 
fibrous, although on the one hand it sometimes approaches the 
character of a Stringybark, on the other hand it is often of a
