EUCALYPTUS PANICULATA. 



The differences of E. jjaniculata from E. largiflorens consist in the contrasting paleness of the 

 lower page of the leaves and in their more copious and more divergent but less prominent veins, 

 in the close approach of the circumferential vein to the margin of the leaf, in the pointed lid, in 

 the deprivation of many of the outer stamens of their anthers and in the narrower rim of the 

 fruit-calyx. It is also generally a taller tree, rising to 150 feet. 



From E. gracilis it diifers again in the inequality of the color of the upper and the lower side 

 of tlie leaves, which are moreover of larger size, in the paniculated inflorescence, more angular 

 anthers not opening at a distance from the summit, and dilated stigma. 



E. crebra and E. microcorys are also not dissimilar to E. paniculata, and mere fruiting sprigs 

 of these three might easily be referred to the wrong species, but in a flowering state the mode 

 of dehiscence of the anthers distinguish them easily from each other, irrespective of several other 

 characteristics. 



From the principal Ironbark-tree of New South Wales, namely E. siderophloia, we can best 

 distinguish E. paniculata by the less deeply furrowed bark, by the frequent difference in the 

 coloration of the leaf-pages, by the shorter calyx-lids, the sterility of the outer stamens, the 

 infraction of all filaments while in bud, the terminal openings of the anthers, the dilated stigma 

 and perfectly enclosed fruit-valves. 



The twigs of E. paniculata are very lax and slender in either variety. The wood is very 

 durable and extensively used by coachbuilders and wheelwrights ; it is often darker than other 

 kinds of Ironbark-timber, but not so tough as that of E. siderophloia. The calyces are generally 

 of pale color. The filaments are almost white, finely capillary, and while in bud slightly 

 flexuous, irrespective of being doubled back. The period of flowering seems a long one, at least 

 that of the variety occurring in South Australia, where blooming panicles have been gathered 

 from December till May ; they are not much scented. The terminal pores of the anthers this 

 species has in common with E. Leucoxylon, E. melliodora and E. polyanthema. The stigma is 

 dilated, sometimes as much as that of E. Leucoxylon. The angularity of the calyx is hardly 

 noticeable in the fresh flowers, but becomes obvious in dried specimens. By an oversight an 

 error of the draftsman has been passed, who delineated the anthers as -opening with longitudinal 

 slits instead of terminal pores. 



The Eev. Dr. WooUs found this Eucalypt flowering more regularly than many other 

 congeners, and noted also, that it produced Kino in considerable quantity and that the bark is not 

 so rugged as that of E. Leucoxylon var. Sideroxylon, but that the wood is easier worked than that 

 of the latter.
