676 SOME NEW SPECIES OF EUCALYPTUS, 



Bloodwood, E. corymbosa, Sm. The figure is occasionally not 

 unlike that of E. maculata, Hook. Gum veins are not infrequent. 

 It is considered a good durable timber, and superior to that of E. 

 corymbosa, Sm. It has quite a metallic ring when the fractured 

 edges of a piece are rubbed together. 



Oil. — The yield from this oil is -125 per cent. It consists very 

 largely of pinene, 58 per cent, of the oil distilling below 172° C; 

 only a trace of eucalyptol could be detected. The specific gravity 

 of the crude oil at 15° C. = -8829. The specific rotation of the 

 crude oil [a] j) = + H'2°. This oil differs from the oil of the 

 Bloodwood of the Sydney district, inasmuch as the latter is lsevo- 

 rotatory to about the same extent. The rotation of the oils from 

 E. corymbosa, Sm., and E. eximia, Schau., and this species varies 

 in about equal proportions, that of the oil of this species being 

 about half-way between those of E. corymbosa and E. eximia, 

 although the constituents of the oils of the three species differ 

 but slightly, being largely pinene. 



E. ANGOPHOROIDES, Sp.nOV. 



"Apple-Top Box." 



(Syn. E. Bridgesiana, Baker, partim.) 



(Plate xlvi., figs. 4a, 46, 4c.) 



A medium-sized tree with a white box bark persistent to the 

 ultimate branchlets. 



Sucker leaves ovate-acuminate, cordate, shortly petiolate, 

 glaucous, variable in size from 1 to 3 or 4 inches long, and 1 to 3 

 inches broad; venation indistinct on both sides. Leaves of mature 

 trees narrow-lanceolate, about 6 inches long, acuminate, not 

 shining, of the same colour on both sides; venation finely marked, 

 oblique, spreading ; intramarginal vein removed from the edge. 

 Oil glands numerous. 



Peduncles axillary, 3 to 4 lines long, slightly compressed, 

 bearing a few flowers. Calyx hemispherical to pyriform, 1 line 

 long; pedicel about 1 line long. Operculum hemispherical, shortly
