" Malice," foliis glaucis; foliis juvenilibus crassis, brevissime petiolatis, lato-lanccolatis ad ovatis 

 v. oblongis, spice distinct.... venis obscuris, venis seeundariis ox costa media 30-40° oriontibus; inflores- 

 eentia glauca, axillari, umbellis ad 7 in capitulo, pediinculis pedicellisque gracilibus; alabastris ovoideis, 

 opercalo bemisphorioo ; antheris E. pi/rifonii > shnWihm; fruetibus hemisphericis, 1-5 cm. diametro, valvis 

 distinct.- i gsi rtis. 



A Malice up fco 35 feet (0. A. Gardner), with glaucous leaves " throughout." Branohlets mostly not 

 angular. 



Juvenile leaves thick, very .shortly petiolatr (while in the opposite state; when more material is 

 available, sessile leaves may bo looked for), broadly-lanceolate to ovate or oblong, under 3 cm. in greatest 

 width and R em. in greatest length, tapering into a distinct apex, intramarginal vein close to the edge; 

 venation indistinct, the secondary veins making an angle of 35 to 55 degrees with the midrib. 



Mat lire leaves rather thick, very shortly petiolate, from lanceolate to nearly ovoid and ovoid- 

 lanceolate, gradually but distinctly apiculate; small, usually about 4 cm. long and rarely attaining 5 cm., 

 but varying in greatest width from under 13 to 25 cm. Venation indistinct, intramarginal vein close to 

 the edge, the secondary veins making an angle of 30-45 degrees (mainly 30-40) with the midrib. 



IllfloroscellCO glaucous, axillary, in umbels up to 7 flowers on slender, slightly flattened peduncles 

 of 1 tin., with pedicels of half that length. Buds ovoid, the operculum hemispherical or with a slight 

 umbo, the calyx-tube very slightly longer than the operculum, and not tapering into the pedicel. Anthers 

 broad, opening laterally in long, oblique slits. They are widest at the base, have a small gland at the 

 top or a little t'> tli" front, filament at the base. Closely allied to E. pyriformis. 



Fruits hemispherical or shallower, about 1-5 cm. in diameter, with a domed rim, and the valves 

 distinctly exsert. 



[In Part LXI I shall explain and freely figure the Floral disc and Capsular 

 disc in Eucalyptus. Subsequently it may be desirable to describe these organs in 

 describing species, and the following is given for E. crucis : — 



Floral disc for ming a carnose covering around the base of and extending half-way 

 up the conical ovary. Staminal ring thin, lower than the top of the calyx. 



( 'apmlar disc broad, domed, free or not fused to the valves of the capsule, 

 slightly higher than the sutural line of the operculum. The Capsular disc is referred 

 to briefly as the rim ami valves of the fruit.] 



Type in. in Southern Cross. Western Australia, Henry Stcedman, April, 1922, 

 from which the drawings were made Further specimens received June, 1922, from 

 the same locality *lio\v, inter alia, broader leaves. These differences have been taken 

 cognisance of in the description. 



The name crucis is given in reference to .Southern Cross; I find that 

 ronomerc have no other Latin nam*- for that constellation, after which the little 

 mining township was named.
