EUCALYPTUS LARGIFLORENS. 



more pyramidal. Mr. O'Shanesy records from the Dawson-Eiver and Nagoa trees with bark 

 black on the stem and grey and smooth on the limbs. 



Preference is here given, in accordance with De CandoUe's code, to the name under which 

 this species was first defined, and chosen as expressive of the exuberance of its flowers. Of neither 

 of the names, bestowed by Allan Cunningham on this species, timely description was given ; the 

 pendulous branches suggesting the one name and perhaps the sometimes red but often pale color 

 of the filaments giving rise to the other, unless it was derived from the coloration of the bark. 

 Crimson filaments seem however not to occur frequently, though the writer has seen flowers of 

 such mixed with others of pale-colored stamens ia the same panicle. Flowers with red filaments 

 are less rare in E. Leucoxylon, occur also in E. Behriana, according to Mr. T. Shepherd rarely in 

 E. hemiphloia and seemingly likewise in E. siderophloia. They are perhaps always red in 

 E. erythronema (Turczaninow, in Bulletin de I'Acad^mie des Sciences de St. Petersbourg 1852 

 p. 415 ; E. conoidea, Bentham, flora Australiensis iii. 227). 



The resemblance of E. Behriana to E. largiflorens is very great, but the former has more erect 

 branchlets, also stiflfer, broader and more shining leaves, the flowers almost unprovided with 

 stalklets, besides often longer fruits. 



E. odorata again is distinguished by the generally broader leaves, simple axillary umbels, 

 more elongated calyces tapering rather more gradually into the stalklets, by longer lids, larger 

 anthers and longer fruits not contracted at the orifice. 



E. microtheca shows more numerous and very spreading veins of the leaves, the circum- 

 ferential vein almost contiguous to the edge, anthers opening by slits not pores, fruits remarkably 

 distended at the orifice with protruding valves. 



E. crebra may be distinguished easily by its dark rugged bark — belonging to the series of 

 the Ironbarks — further by the fine close and very spreading veins of the leaves and by the anthers 

 opening by fissures. 



Bentham's var. parviflora of E. largiflorens belongs to E. populifolia.
