EUCALYPTUS ERYTHRONEMA. 



Turczaninow, in Bulletin de 1'Academic des sciences de St. Feterabonrg 1862, p. 415 ; E. conoidea, Bentham, flora 



Australiensis iii. 227. 



Branchlets almost cylindrical ; leaves comparatively small, scattered, short-stalked, generally 

 narrow-lanceolar, nearly straight or somewhat curved, of equal color and rather shining on both 

 sides ; lateral veins subtle, some not much spreading, none crowded, the circumferential vein 

 distinctly removed from the edge of the leaf ; oil-dots very copious, transparent ; umbels recurved, 

 axillary and lateral, solitary, 3-6-flowered ; stalks cylindrical, shorter than the stalklets or hardly 

 as long ; tube of the calyx almost topshaped, very gradually attenuated at the base, somewhat 

 streaked, usually about half as long as the conical lid ; stamens all fertile, sharply inflexed before 

 expansion ; filaments red, rather thick and angular ; anthers pale, oblong, nearly basifixed, 

 opening in their whole length by almost marginal slits ; their gland not tumid ; style longer than 

 the stamens, thickened at the summit ; fruit broadly topshaped, surrounded beneath the broad and 

 Jlat rim by an annular impression, the tube not angular ; valves 4-5, short, deltoid, affixed to the 

 summit of the orifice ; fertile seeds considerably larger than the sterile seeds, all without any 

 appendage.

Height of this Eucalypt unrecorded, not likely considerable. Most leaves between 1^ and 

 24 inches long, and between and f inch broad, some occasionally oblong. Umbels sometimes 

 crowded on the branchlets. Umbel-stalks usually from to inch long, downward or spreadingly 

 bent, a characteristic not expressed in Mr. Todt's drawing, in which also the flowerstalklets of 

 two of the umbels became too much abbreviated. Stalklets not angular. Tube of the flowering 

 calyx hardly ^ inch long, but soon enlarging, and then not rarely the edge turning outward ; lid 

 when well developed about an inch long, and its summit conspicuously attenuated, but excep- 

 tionally much shortened and assuming a hemiellipsoid form. Stigma depressed-hemispheroid, 

 not dilated beyond the style-summit. Ripe fruit attaining a length of ^ an inch, shining, not 

 angular, the annular furrow at first vertical and then the disk convex, the latter occupying rather 

 an ample space between the valves and the edge of the fruit ; valves convergent and thus 

 scarcely emersed, though terminal. 



This species of Eucalyptus was first described from the collections of Mr. James Drummond, 

 who however attached to none of the very numerous specimens of West-Australian plants, 

 gathered by him through 40 years, any notes on localities and habit. The leaves remind of those 

 of E. amygdalina, though they are smaller ; the lid is much like that of E. tereticornis ; the fruit 

 is not very simlar to that of any other congener. 



As regards utility E. erythronema has evidently value for oil-distillation, while the rich color 

 of its filaments, from which the specific name was derived, give it some claim for a place in 

 ornamental shrubberies. 



This is one of the enormous numbers of endemic plants, for which the vegetation of extra- 

 tropical Western Australia is so remarkable, the genus Eucalyptus forming there no exception to 

 that rule, inasmuch as out of 36 well-marked extratropical species, known from there, 29 are not 

 occurring in any other portion of Australia ! The list of these peculiar western Eucalypts is here 

 adduced : 



E. marginata, E. buprestium, E. sepulcralis, E. decipiens, E. macrocarpa, E. Preissiana, 

 E. megacarpa, E. erythronema, E. ctesia, E. tetraptera, E. salmonophloia, E. leptopoda, E. salu-
