Eucalyptus eugenioides, Sieb. 
A White Stringybai'K. 
(Family MYRTACE^E.) 
Botanical description. —Genus, Eucalyptus. (See Part II, p. 33.) 
Botanical description. —Species, E. eugenioides , Sieb., in Sprengel’s Curce 
Posteriores, iv, 193 (1827). 
The species may be defined as follows :— 
Juvenile foliage. —Specimens of the type (Sieber’s No. 479) are just—only just—past the 
opposite stage. They are lanceolate, under f inch wide at the outside, and up to 2| inches 
long. Venation strongly marked. Leaves undulate and young shoots warty. (Figured 
at A on the plate.) 
Mueller lias figured* the juvenile foliage of the species in the Eucalypto- 
gmphia, and I accept it as certainly belonging to the species, although the figure 
would have had enhanced value had the locality of the specimen been given. 
Mature leaves. —These are generally much thinner and more delicate in texture than those of 
E. capitellata and E. macrorrhyncha ; the leaves are sometimes very shiny and much thicker 
than others. They are also of a richer green, more shapely, graceful and Eugenia- like, a 
circumstance which led to the adoption of the specific name. 
Buds. —The buds are clustered and often very much crowded into heads, by which the inflorescence 
assumes a very marked character. They always have pointed opercula, but rarely angular, 
as in E. capitellata, the points being sometimes so marked as to approach those of 
E. macrorrhyncha , but they are then fuller on the top, and do not show such a prominent 
edge at the base of the operculum. Sometimes, e.g , Sydney to Blue Mountains, they are 
arranged in a stellate manner. 
Fruits. —Sieber having distributed no fruits with his type, I attach the following description of 
fruits from trees in the Sydney district, which have juvenile and mature leaves and flowers 
practically identical with the type :— 
They are nearly hemispherical, with the valves slightly exsert; but nearly globular fruits 
with the valves sunk, and the orifice constricted, maybe taken off the same tree. Occasionally 
the fruit is quite flat-topped. The rim is often red, as red as those of E. hwmasloma ever 
are. They are slightly pedicellate, often crowded into more or less globular heads, but 
rarely compressed like those of E. capitellata. 
• Mueller’s figure shows a leaf longer than broad ; in E. capitellata we have a distinctly broad leaf. In some forms 
referable to E. eugenioides we have a very narrow leaf. I have no hesitation in saying that a narrow juvenile leaf is the 
standard or type for E. eugenioides and a broadish one for E. capitellata. The difficulty, of course, begins with the 
intermediate forms. In many cases one cannot state whether the juvenile foliage is narrow or broad, and evidenco 
furnished by other characters is, in some cases, difficult to interpret.
