DICHOTOMOUS KEY TO THE EUCALYPTUS. 11 



No. No. 



117. Pedicels very slender, at least three times as long as 



the calyx, E. leptopoda. 

 Pedicels short ... ... ... ... ... ... 118 



118. Operculum conical or acuminate, longer than the calyx 119 

 Operculum hemispherical, mostly blunt, usually shorter 



than the calyx ........... , ... 120 



119. Flowers shortly pedicellate, E. redunca. 

 Flowers sessile, E. concolor. 



120. Leaf -veins fine, numerous, very divergent ... ... 121 



Leaf-veins not numerous, very oblique ... ... 122 



121. Stamens of expanded flowers, straight, E. cneorifolia. 

 Stamens of expanded flowers bent inwards about the 



middle, E. uncinata. 

 (E. micranthera is a variety of this.) 



122. Peduncles conspicuously flattened near the top, E. 



salubris. 

 Peduncles nearly or quite terete ......... 123 



123. Leaves under 3 inches long ... ... ... ... 124 



Leaves mostly over 3 inches long ... ... ... 125 



124. Fruit almost flat on top, E. cocci/era. 



Capsule somewhat sunk below the narrow rim, E. 

 Gunnii (typical.) 



125. Fruit topshaped, leaves somewhat undulate, E. 



Gunnii, var. 



(I doubt whether Baron Von Mueller was correct in includ- 

 ing this tree in E. Gunnii as a variety in his Eucalypto- 

 graphia, where the main figure represents it. Bentham's 

 description of E. Stuartiana refers partly to this. Perhaps 

 it will be necessary to distinguish it as a separate species, 

 and the name of E. undulata would not be inappropriate.) 



Fruit ovate or globose, truncate ... ... ... 126 



126. Rim of fruit narrow, the valves inserted somewhat 



below it .................. 127 



Rim of fruit rather broad and flat ... ... ... 128 



127. Flowers generally 3 in an umbel, E. Bauerleni. 



(The real affinity is with E. vimincdis.) 

 Flowers more than 3 in an umbel, E. eugenioides. 

 (The real affinity is with E. piperita.) 



128. Leaves very pale, bark of stem hard and rugged, E. 



Sieberiana. 

 Leaves green, bark of stem smooth or fibrous ... 129 



129. Fruit ovate-truncate, top of fruit reddish, E. haemas- 



toma. 

 Fruite globose, truncate or shortly ovate ... ... 130 



130. Leaves rather small, their oildots large and not very 



numerous ; stem-bark fibrous, E. amygdalina. 

 (E. dives is an aberrant form of this. There is a variety 

 in Tasmania with linear leaves.)
