Eucalyptus adjuncta n. sp. 



Arbor alta, "Grey Gum," ligno atro-rubeo. Foliis maturis 

 petiolatis lanceolatis, rectis vel falcatis, venis secundariis patent- 

 ibus non prorainulis. Alabastris axillaribus, umbel lis 3-floris in 

 duobus paribus, pedunculis pedicellisque gracilibus, calycis tubo 

 obconico, operculo rostrato 1 cm. longo. Fructibus hemispherico- 

 conoideis, ca. 1 cm diametro, calycis tubo lseve margine distincta, 

 capsule© valvis valde exsertis. 



A tall tree of 70 or 80 feet, with a diameter of 3 or 4 

 feet (Andrew Murphy); the bark smooth, and somewhat 

 rough in patches, like that of a Grey Gum; timber deep 

 red. 



Juvenile leaves. What are known as "suckers" (adven- 

 titious shoots) are not available, but a young seedling with 

 leaves of medium width. 



Mature leaves small (as far as the material is available), 1 

 petiolate, lanceolate, straight or falcate, tapering gradually 

 to the apex, without lustre, secondary veins not prominent, 

 spreading, the midrib and marginal vein pink in colour. 



Buds axillary, usually in two pairs of three flowered 

 umbels, peduncles slender, 1 cm. long and more, decurved, 



1 The original material was mislaid. When subsequent search was 

 made for the original trees it was found that the group of three had ben 

 destroyed in the v\ idening of the Line, and others have not 3 et been found. 

 The belaied description is jullisLed now, in the hope that other trees 

 may be traced. . ;
