Eucalyptus viminalis Labill. 
"' A WM te Gum. 
(Family MYRTACE^E.) 
Botanical description. Genus, Eucalyptus. See Part II, p. 33. 
Botanical description. Species, viminalis Labill., Nov. Roll. PI. ii, 12, with 
plate 151 (1806). 
A copy of the original description will be found in my " Critical Revision of 
the Genus Eucalyptus," Part XXVIII, p. 167, and following is an unpublished 
translation : 
A Eucalypt, operculum rather hemispherical, mucronate ; leaves linear-lanceolate ; heads 
3-flowered, lateral. A medium-sized tree, branchlets angular at the apex. Leaves linear- 
lanceolate, acuminate, nervelets hardly distinct, length the breadth of the palm to that of 
a small span; petiolate, alternate. Flowers on a common axillary peduncle, somewhat 
two-edged, scarcely the length of the petioles, very often 3 cruciform, the central one having 
a longer pedicel than the others. Calyx semi-globular, the operculum a little shorter than 
the calyx and coriaceous. Style rather shorter than the stamens, stigma subcapitate. 
Capsule globular, calyx corticate, half covered, 3-4 celled. Otherwise similar to the preceding 
species (E. incrassata). Habitat, Cape Van Dieman. 
Bentham then describes it in B.F1. iii, 239, in English.

Botanical Name. -Eucalyptus, already explained, Part II, p. 34; viminalis, 
Latin, twiggy, a term mostly applicable to small saplings and to the branches of small 
trees. Subsequently the species was found to attain large dimensions, particularly 
in the mainland States, when the specific name ceased to have special appropriateness. 
Varieties. The normal number of flowers is three, but the species is often 
multi-flowered. This is discussed in my " Critical Revision of the Genus Eucalyptus," 
Part XXVIII, p. 169. 
1. Var. rhynchocorys F.v.M., with a pointed operculum. Type from the Snowy 
River (Victoria and New South Wales). 
This pointed operculum is not rare ; on the other hand, it is not common. We 
also have it from Fernshaw, Victoria (Jefferson), from Melb. Herb., and from the Swansea 
district, Eastern Tasmania (late Dr. Story), and a few other specimens. 
2. Var. racemosa F.V.M. The type appears to be Port Phillip, February, 1880.
