This species is one of the most unsatisfactorily defined of the early species. 
The extreme brittleness of the wood, and the large quantity of “resinous gum,” at 
once show that the tree now understood as E. resinifera is quite a different species. 
The original figure of the bark, and the description of the wood and resinous 
exudation, apply exactly to Angophora lanceolata. The figures of the buds apply 
fairly well to the Red Mahogany, and doubtless assisted in causing Bentham to 
describe that tree under the name Eucalyptus resinifera, Smith. Eucalyptus 
Stuartiana, F.v.M., one of the Apple-trees, is another of our Eucalypts which were 
originally described from different material from that now understood as the species. 
Eor a number of years E. resinifera was an unsatisfactory species, and 
Bentham re-defined it by describing the Bed or Eorest Mahogany under that 
name. 
Following is Bentham’s description :— 
A tall tree with a rough persistent bark on the trunk, but more or less deciduous on the 
branches. (Woolls and others.) 
Leaves. —Ovate-lanceolate to lanceolate, acuminate, straight or falcate, mostly 4 to 6 inches long, 
rather thick, with numerous fine close parallel and almost transverse veins, sometimes 
scarcely conspicuous, the intramarginal one close to the edge. 
Peduncles. —Axillary or lateral, more or less flattened, each with about six to eight, or sometimes 
more, flowers on pedicels usually short, but sometimes longer than the calyx-tube. 
Calyx-tube. —Broadly turbinate, 21,- to 3, or rarely 4, lines in diameter. 
Operculum. —Conical or acuminate, much longer than the calyx-tube, and often broader at the 
base, as in E. tereticornis. 
Stamens. —4 to 6 lines long, raised above the calyx-border by the disk, inflected in the bud ; 
anthers small, ovate, with parallel distinct cells. 
Ovary. —Not much shorter than the calyx, conical in the centre. 
Fruit. —Obconical, subglobose-truncate or almost hemispherical, not contracted at the orifice, the 
rim not broad, convex, or prominent, the capsule somewhat sunk, or nearly level with it, the 
valves protruding. (B.F1. iii, 245.) 
There are several forms of this species, viz. :— 
(A.) Normal, or small-fruited form. 
(B.) Large-fruited forms, including— 
1. Var. grandijlora, Benth.. 
2. Var. Kirtoniana, Deane and Maiden. 
B.— Large-fruited Forms. 
Much more variation is undoubtedly presented by E. resinifera in its large- 
fruited than in its small-fruited forms. 
1.—Variety grandijlora, Benth.; B.F1. iii, 246. 
This variety includes E. pellita , F.v.M., and E. spectabilis , F.v.M., and a 
series of closely allied forms bearing very near affinity to typical E. resinifera.
