1104. Frutescent ; leaves rather small, with closely ap- 



proximated secondary venules. 



Always shrubby ; leaves firm, from linear- to narrow- 

 lanceolar, almost straight, copiously dark- dotted, often 

 hooked-pointed, their secondary venules subtle, much 

 spreading ; flowers quite small ; lid usually semi-ovate ; 

 filaments sharply infracted before expansion, without 

 flexuosity ; anthers very minute, almost globular ; fruit 

 small, semi-ovate, its border depressed or flat ; valves 

 barely enclosed or slightly exserted. One of the 

 "Mallees." E. iiiicinata. 



Arborescent ; leaves rather large, with distant 

 secondary venules. 



A tree, but never tall ; bark persistent, rough, hard ; leaves 

 firm, from narrow- to broadish-lanceolar, somewhat uni- 

 laterally curved, their secondary venules rather slightly 

 spreading ; umbels occasionally short-paniculated ; lid 

 from broad-conical to pointed-hemispherical ; anthers 

 minute, almost roundish ; stigma slightly dilated ; fruit 

 nearly semi-ovate or hemi-ellipsoid, its border compressed 

 and annular- margined ; valves rather deeply enclosed. 

 South Australian "Peppermint-tree." E. odorata. 



1105. Leaves of thin texture ; calyx-lid double. 



Rather tall ; bark persistent, rough ; leaves from narrow- 

 to rather elongate-lanceolar, equally dull-green, slightly 

 curved, their secondary venules subtle, moderately 

 spreading ; oildots numerous, often transparent ; inner 

 lid hemispheric, less wide than the calyx-tube ; outer 

 stamens sometimes partially without anthers, the latter 

 globular, minute ; fruit quite small, usually truncate- 

 ovate, its border compressed ; valves very short, quite 

 enclosed. One of the " Box-Eucalypts." 



E. largiflorens. 



Leaves of thick texture ; calyx-lid single 1106 



1106. Leaves dull-green or ashy- whitish; fruit hemi-ellipsoid. 



Finally tall ; bark rough, persistent, greyish outside ; leaves 

 from elongate- to ovate-lanceolar, unilaterally somewhat 

 curved, their secondary venules prominent and moderately 

 spreading; calyx somewhat angular, its lid nearly as 

 long as the tube, semiovate-conical, acute ; fruit-border 

 compressed; valves deeply enclosed. One of the "Box- 

 Eucalypts." E. hemiphloia.
