It differs from D. taxifolia in being a more erect and 

 higher growing shrub, and the leaves being distinctly- 

 decussate and not nearly so much crowded, larger and 

 flatter, and not glaucous. Its flowers are also more fleshy r 

 and the calyces lack tlie ribs so prominent a feature in 

 both the other species. The bracts also differ in shape 

 from both species, whilst the disposition and the shape of 

 the leaves clearly separate it from D. fascicularis. 



Chemically the constituents obtained from the leaves- 

 place the oil intermediate between those of its congeners- 

 Description of Species. 



It is an erect shrub growing to a height of fifteen feet, 

 never arborescent as far as seen, with reddish terminal 

 branchlets. 



Leaves decussate, distant in the upper branchlets, and 

 never so close together or crowded as in D. taxifolia and 

 D. fascicularis, nor glaucous as obtains in the former 

 species; falcate, laterally compressed, acute, 7 to 8 lines 

 long, the mid-rib not showing, the upper surface channelled 

 with acute edges, oil glands not so pronounced as in the 

 above species, uniform colour to the articulation with the 

 decurrent petiole in the stem. 



Flowers terminal, about 5 lines long, in clusters of 3 to 4, 

 pink, white, and green in colour. 



Bracteoles broad, with scarious edges, oil glands very 

 numerous, acuminate, not so long as the calyx. 



Calyx fleshy, the lower half quite round, not ribbed or 

 corrugated, shining and much pitted, the upper portion 

 with five narrow channels between each portion of sepal, 

 which may be said to be here valvate, the free lobes small, 

 acuminate and incurved. 



Petals white, broad, about 1 line long.
