DESCRIPTIONS OF NEW AUSTRALIAN PLANTS, WITH 

 OCCASIONAL OTHER ANNOTATIONS ; 



By Baron von Mueller, K.C.M.G., M. & Ph.D., LL.D., F.R.S. 



(Continued.) 

 Atriplex lobativalve. 



F. v. M., " Iconogr. of Austral. Salsolac. Plants," t. vi. 



Prostrate, grey from a very short somewhat lepidote and 

 papillular vestiture ; leaves small, mostly somewhat rhomboid 

 in outline, cuneated into the short petiole, often upwards bluntly 

 short-lobed ; clusters of staminate flowers at and towards the 

 summit of the branches, hardly exceeding the leaves or shorter ; 

 pistillate flowers in lower positions, sessile, only few together in 

 each axil, their two segments divergently and deeply cleft into 

 five lobes but devoid of appendages, the two lower lobes almost 

 deltoid, the three other lobes nearly semilanceolar ; radicle 

 ascending. 



Near the Marshall-River, Winnecke; at Lake Yantara, Bauerlen. 



Seemingly annual. Allied to A. velutinellum and A. ftssivalve. 



Although this and the following plant were illustrated already 

 1889 and 1891 respectively, as yet no diagnoses of them had 

 been furnished. 



Bassia longicuspis. 



F. v. M., " Iconogr. of Austral. Salsolac. Plants," t. 24. 



Nearly glabrous ; branches streaked ; leaves rather long, almost 

 cylindric-filiform, acute ; flowers solitary ; stigmas two ; fruiting 

 calyx with ample and hollowed base sessile, usually by about 

 half longer than broad, terminated by four setaceous-subulate 

 spinules, two of which several times longer than the calyx, the 

 other two or one much shortened; seed longer than broad; 

 radicle ascending and considerably extending beyond the 

 cotyledons. 



Charlotte-Waters, Rev. H. Kempe ; Beltana, Mrs. Richards ; 

 Darling-River, Mrs. Kennedy. 



Fruiting occasionally at a height of some few inches already, 

 and probably never tall. Allied to B. Forrestiana. 



Leucophyta Lessingi. 



De Candolle in 1837 mentions both for Leucophyta and 

 Calocephalus the first specific names as given by Lessing, but 

 Kuntze in his " Revisio Generum Plantarum " (1S91) has shown, 

 that already Cassini in 1832, therefore nine years earlier, gave 

 a specific name to Leucophyta, whereas Calocephalus was then 

 left yet without any appellation for its species. Kuntze therefore 

 makes Leucophyta supersede Calocephalus, and consequently 

 the 10 species of the latter genus appear in his work (p. 351)
