242 Key to the System of 



Calyx-lid from below hemispheric upwards sharp- 

 pointed ; outer stamens inflexed before expansion. 



Finally tall ; bark extensively smooth and outside whitish ; 

 leaves generally from narrow- to elongate-lanceolar, often 

 much unilaterally curved ; secondary venules numerous, 

 thin, very regularly spreading ; umbels solitary, with 

 several flowers ; stalks rather elongated ; stalklets very 

 conspicuous, quite slender ; tube of the calyx nearly 

 hemispherical, hardly half as long as the lid ; anthers 

 nearly oval ; calycine portion of fruit semiglobular ; 

 border convex, protruding ; valves finally quite exserted, 

 nearly deltoid. " Red Gum-tree." E. rostrata. 



1118. Umbels paniculated. 



Finally tall ; bark persistent, rough ; leaves firm, somewhat 

 flexible, from ovate- to elongate-lanceolar, almost equi- 

 lateral, dark-green above ; secondary venules almost 

 pennular-approximated, subtle, nearly transversely 

 spreading, th6 circumferential venule almost contiguous 

 to the edge of the leaf ; umbels large -flowered ; stalklets 

 elongated ; lid short, tearing off on an irregular 

 transverse line ; filaments light-yellowish ; anthers ovate- 

 elliptical ; fruit large, ellipsoid -urnshaped, its border 

 compressed ; valves deeply enclosed ; fertile seeds large, 

 expanding into a short or narrow appendicular mem- 

 brane. "Blood wood-tree." E. corymbosa. 



Umbels solitary ... 1119 



1119. Umbel-stalk broadly compressed ; fruit hemiellipsoid. 



Finally tall; bark persistent, dark, rough; leaves elongate or 

 broadish-lanceolar, slightly unilateral-curved, dark-green 

 above ; secondary venules almost pennular-approximated, 

 subtle, nearly transversely spreading ; stalklets of 

 flowers very short or obliterated ; calyx-lid nearly hemi- 

 spherical ; anthers almost oval ; fruit slightly angular, its 

 border compressed ; valves barely enclosed, quite short. 

 One of the " Mahogany-Eucalypts. " E. botryoides. 



Umbel-stalk nearly cylindrical; fruit urnshaped- 

 ellipsoid. 



Finally rather tall ; bark smooth, outside whitish ; leaves 

 from elongate- to broadish-lanceolar, shining, somewhat 

 unilaterally curved; secondary venules rather distant, 

 moderately spreading; umbels sometimes crowded; stalk- 

 lets conspicuous ; lid almost hemispheric, slightly over- 

 reaching the rim of the calyx, much shorter than the 

 tube ; anthers almost oval ; fruit longitudinally streaked, 

 its border compressed ; valves deeply enclosed. " Sugary 

 Gum-tree." E. corynocalyx.
