DESCRIPTION. 



CCCLL E. cruris n.sp. 



"Malleu," foliis glaucis; foliis juvenilibus crassis, brevissime petiolatis, lato-lanceolatis ad ovatis 

 V. oblongis, apice distincto, venis obscuris, venis secundariis ex costa media 30-40° orientibus; inflores- 

 centia glauca, axillari, umbellis ad 7 in capitulo, pedunculis pedicellisque gracilibus; alabastris ovoideis, 

 operculo hemispherico ; anther-is E. pyriformi similibus ; fructibus hemisphericis, 1-5 cm. diametro, valvis 

 distinctc exsertis. 



A Mallee up to 25 feet (C. A. Gardner), with glaucous leaves "' throughout."' Branchlets mostly not" 

 angular. 



Juvenile leaves thick, very shortly petiolate (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 6 cm. in greatest length, tapering into a distinct apex, kitramarginal vein close to the edge; 

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



Mature 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. 



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

 of 1 cm., 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 to the 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. 



[Iii 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 forming 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. 



. Capsular 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 and valves of the fruit.] 



Type from Southern Cross, Western Australia, Henry Steedman, April, 1922, 

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

 the same locality show, 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 

 astronomers have no other Latin name for that constellation, after whieh the little 

 mining township was named.
