Botanical Name. — Eucalyptus , already explained. (See Part II, p. 34.) 
Planchoniana, in honour of the late M. J. E. Planchon, formerly Director of the 
Botanic Garden of Montpellier, Southern Prance. 
Following is Mueller’s original dedication :— 
“ Spec-iem dicavi amico J. E. Planchon, horti botanici Montis Pessulani digno Directori, qui 
tractatum de Eucalyptis eximium scripsit (‘Revue des Deux-Mondes,’ Janvier, 1875) et inter primos 
Eucalyptum Glohulum ad mare mediterraneum e seminibus me transmissis culturae subjecit.”— (Fragtn., 
xi, 43.) 
Vernacular Name. —Because it is, when straight and large enough, cut up 
for Tallow-wood, it is known as Bastard Tallow-wood, when indeed it is not called 
Tallow-wood without any qualification. 
It is sometimes called Stringybark. 
Aboriginal Name. —I know of none. 
Leaves. —"When quite a young sapling the leaves of this tree are of a rich 
purple colour, giving it a decidedly ornamental appearance. 
The fresh leaves yield ’06 per cent, of an essential oil, having a specific 
gravity of - 915 (Staiger). 
The odour of this oil is described as peculiar, allied to citronella, hut differing 
from it. It has been suggested as a soap-perfume.

Fruit. —This tree bears the largest fruit of any of our New South Wales 
species of Eucalyptus, the shape of the fruit being ovoid, with raised longitudinal 
ribs. Mr. Forester Brown, of Port Macquarie, showed me a fruit of this species 
1-g inch broad by 1 inch deep, when dried. 
The ribbing of the fruits is omitted in Mueller’s drawing in the 
“ Eucalyptographia.” 
Back.—Because of its fibrous bark it is locally known as a “Stringybark,” 
but it is more like Bed Mahogany. The bark is rough to the ultimate branchlcts. 
It has otherwise been described as having a bark nearer to that of E. rohusta, the 
“ Swamp Mahogany.” 
Timber.— T 'his timber is sound, heavy, hard, and durable, well adapted for 
sawing, but not easy to split, according to Bailey, speaking of Queensland timber.
