AUSTRALIAN PLANTS. 69 



Hab. On the sandy, sometimes inundated, banks of the Murray. 

 This presents the first Australian species of this genus/ and must be 

 systematically placed next to M. Mrta, from the Cape of Good Hope. 



XXI. Paronychie^. 



84. Mniarum singuliflorum, F. Muell. {Scleranthus mniaroides, F. 

 Muell. collect.); stems csespitose, somewhat flaccid; leaves upright or 

 little patent, as well as the branches smooth, Isevigate ; peduncles one- 

 flowered, at the top bibracteate ; calyx turgid, five-cleft. 



Hab. On bare rocks at the summit of the Cobboras Mountains, 

 6000 feet above the level of the sea. 



Easily to be distinguished by the above notes from M, biflorum (M, 

 fascicidatum, E. Br., -S'. Mniarum, F. Muell.), the only known species, 

 and like this varying in the length of the peduncles. By the con- 

 stantly five-cleft calyx of this kind, Mniarum becomes so closely allied 

 to Sclera7ithiis, that hardly any objection can be raised against the con- 

 junction of the two genera. 



XXII. CUNONIACE^. 



85. Bauera 5(?55z7^ora,* F. Muell.; hirsute; leaves lanceolate or sub- 

 ovate, generally entire ; flowers axillary and terminal, sessile, pseudo- 

 verticillate ; calyces to the middle eight-cleft, w^ith subulate-lanceolate 

 or linear segments, and with a slightly ribbed obconico-cylindrical tube; 



petals purple; stamens about twelve; anthers oblong-ovate, emarginate, 

 black. 



Hab. On the rocky, subalpine summit of Mount William, and thence 



descending along the rivulets into the valleys. 



Flowers larger and of a much deeper colour than in Bauera Billar- 

 dieri. 



XXIII. UMBELLIFERiE.f 



86. Yi^Avocoi^le pterocaiy a, F. Muell.; Subglabrous; stems creep- 

 ing ; leaves orbicular-reniforra, indistinctly five- to seven-lobed, crenu- 

 late-repand ; stipules broad, membranaceous, not fringed ; petioles 

 longer than the downy, solitary peduncle; umbels generally many-
