Finally tall ; leaves scattered, from broad- to narrow-lanceolar, more or less curved, gradually 

 pointed, mostly of equal dull green on both sides ; their lateral veins subtle, very spreading, the 

 circumferential vein somewhat removed from the margin of the leaf; oiUdots largely pellucid ; 

 umbels axillary, solitary, on conspicuous slender stalks, three- to eight-flowered ; calyces on 

 rather short stalklets, not angular ; their tube almost topshaped or somewhat bellshaped, nearly 

 as long as the broad-conical lid or somewhat shorter ; stamens all fertile, inflexed before expansion 

 except some of the outermost ; anthers ovate, with contracted base, opening by parallel slits ; 

 stigma not broader than the style ; fruit turbinate-hemispherical, three- to five-celled ; its margin 

 depressed, comparatively broad ; valves deltoid, quite exserted; fertile seeds broader but mostly 

 not longer than the sterile seeds, all without any appendage. 



On river-banks and around swamps from the neighborhood of Swan-River to Cape Leeuwin 

 and thence eastward at least as far as the Gardiner-Eiver. 



One of the " Flooded Gum-trees " of Western Australia, passing in some places also as a 

 " Swamp Gum-tree " and " Blue Gum-tree." A tree, usually not of very tall growth, although 

 sometimes rising to 80 feet. Bark rough, persistent. Leaves generally rather thin in structure, 

 not rarely somewhat sickleshaped, only occasionally shining, like those of several other congeners 

 often reddish at the margin. Umbel-stalks ^-1 inch long. Flowers not quite small. Stalklets 

 sometimes rather longer than the calyx-tube. Commissural line between the lid and tube of the 

 calyx rather prominent, by which characteristic this Eucalyptus can readily be distinguished from 

 allied species. Lid rather shining, slightly concave between its base and summit. 



This species, so far as observed by the writer, expands its flowers from September tiU 

 November. Mr. James Drummond numbered this also 10 in his collections. 



E. rudis is one of the species rich in volatile oil of its foliage ; this therefore is an apt 

 opportunity to continue the medical notes on Eucalyptus-oils, as given partly already in the 

 text of E. acmenoides and E. eugenioides of this decade and in some pages of the seventh decade. 

 As important in internal therapy the Euc.-oil became first known when used against intermittent 

 fever, although most medicinal preparations for this purpose contain also other active principles 

 of the Eucalyptus-leaves, to which partially the antipyretic value seems due, as pointed out 

 already in the article on E. globulus. Professors Lorinser and Keller used a tincture in their 

 extensive experiments. The latter physician reports, that in 432 cases of ague, under his 

 treatment, 310 became cured, and — what seems astounding — 202 after the first dose of the 

 tincture, no relapse occurring ; but perhaps this seemingly splendid result may have been due 

 partly to the changed location of the patients. Prof. Keller farther observes, that of 118 patients, 

 who derived no benefit from quinine, 91 recovered after the use of the Eucalyptus-tincture. 

 Many other similar results are mentioned in pathologic literature, although not so numerously 

 illustrated. Prof Rosenstein saw good efi'ect from Eucalyptus in ague, when even arsenic failed ; 

 the tincture used by him is from 1 part leaves and 8 parts spirits of wine, the daily dose being 

 1-J ounce ; but he found, that in recent cases of ague the action of Eucalyptus is not equal to that 

 of quinine. The antifermentive power of Eucalyptus must act very favorably irrespective of the 

 lowering effect on the temperature of the body, as noticed not only in intermittent fever, but also 

 in acute rheumatism, traumatic fever, typhus and typhoid fever, as first noticed by Drs. Mosengeil,
