EUCALYPTUS SALMONOPHLOIA.

Finally tall ; branchlets thin, slightly angular ; leaves scattered, of rather thin consistence, 

 sickleshaped- or narrow-lanceolar, shining and of equal color on both sides ; their lateral veins 

 spreading at an acute angle, very much concealed, the circumferential vein but slightly removed 

 from the edge of the leaf ; oil-dots copious ; umbels solitary, axillary or soon lateral, containing 

 ten or fewer rather small flowers ; stalks thin, nearly cylindrical ; stalklets about as long or 

 somewhat shorter than the semiovate tube of the calyx; lid conical-semiovate, slightly longer than 

 the tube ; stamens all fertile, the outer before expansion not indexed; anthers roundish, opening 

 by longitudinal slits ; stigma not broader than the summit of the style ; fruits small, nearly 

 semir-ovate, three- or rarely four-celled ; valves exserted, almost awlshaped-pointed ; fertile seeds 

 very small, not prominently angular, nor provided with any appendage ; sterile seeds very minute. 



From the upper eastern part of Swan-Eiver and its affluents (F. v. M.) extending to Victoria- 

 Spring through the arid interior region but not continuously (E. Giles). 



A tree, when aged, attaining to fully 100 feet height, known vernacularly as the " Salmon- 

 colored Gumtree," in allusion to the smooth grey and somewhat purplish bark of an oily lustre. 

 Leaves on stalks of moderate or not very great length, generally between 3 and 5 inches long, and 

 between ^ and | of an inch broad, occasionally however broader, pointed at the summit, gradually 

 narrowed at the base, not very inequilateral, though curved. Umbel-stalks ^ to f of an inch long. 

 Lid about ^ of an inch high. Filaments yellowish-white. Fruits ^^ of an inch broad. Fertile 

 seeds mostly ellipsoid, only about | a line long, slightly concave on the inner side. 



The nearest affinity of this species is to E. leptopoda ; the leaves however are shorter, 

 smoother, shining and more visibly perforated by oil-dots, the flowers are fewer in the umbels, 

 their stalklets shorter and their lid blunter ; the outer filaments are not all bent inward while in 

 bud ; the fruits are smaller and particularly less broad, while the valves are narrower and longer ; 

 besides the flowers of E. leptopoda in an expanded state and its ripe seeds require yet to be 

 compared. Drummond's plants 151 and 188, referred by Bentham to E. leptopoda, represent 

 E. salmonophloia. E. salmonophloia has also some characteristics in common with E. oleosa ; 

 but it is taller, the bark is very different, the leaves are thinner in consistence and darker in color, 

 the flowers are smaller, the lid is shorter and blunter, and the fruits are also of lesser size. 



As this is one of the oil-yielding Eucalypts, it will be opportune to add to the notes on the 

 medical properties of Eucalyptus-oil, which were partly given in the article on E. salubris, although 

 the hitherto recorded experiences are from the oil of E. globulus, or oftener still from that of 

 E. amygdalina. The physiologic influence of the oil on blood is specially alluded to in Professor 

 Hugo Schulz's essay, already quoted. He noticed, that blood coming in contact even with very 

 small quantities of Eucalyptus-oil gets quite dark and coagulates. Also Dr. Schlaeger already in 

 1874 recorded, that blood of animals treated with this oil shows hardly any difference in color, 

 whether venous or arterial, the red corpuscles becoming deprived of the means to absorb oxygen. 

 Drs. Mees and Binz ten years ago also observed, that the mere addition of one part of ordinary 

 Eucalyptus-oil to 1500 parts of blood destroys in flfteen minutes the contractibility of the white 

 corpuscles. 



In pathologic studies it was found, as first recorded by Professor Mosler in 1872, that the 

 administration of Eucalyptus-oil reduced the volumen of the spleen. From Dr. Schlaeger's
