AUSTRALIAN PLANTS. 3 



^ 3. Myosuriis Australis* F. MuelL ; scape filiform or setaceouy, up- 

 wards but slightly thickened ; petals and sepals very small ; fruit-spike 

 narrowly terete, somewhat acute, about an inch long ; carpels numerous, 

 closely inti'icate, rhomboid or almost deltoid, acuminate at the thickened 



base, slightly spreading ; styles very short. 



Hab. On moist places or on the open plains where rain-water lodges 

 for a considerable time, near the Emu Creek, Hopkins Eiver, Avoca, 

 Avon, Eichardson, and Murray, sometimes abundant. 



It is not a little surprising that this genus, of which hithei-to only 

 two species, namely, M, minimus from Eux'ope, and M, aristatiis from 

 the Cordilleras of Chili, have been noticed, should find its representa- 

 tive also in Australia. Our species is closely allied to Jf, minimus ; it 

 differs chiefly in the loose extra-curved bases of the carpels. 



4. Caltha introloba^ F. MuelL ; dwarf; leaves on long petioles, has 

 tate-ovate, notched at the summit, perfectly entire, enlarged at the base 

 by two long lobes ; these bend inward, are oblong-linear and dilated 

 below ; scape one-flowered, very short ; sepals white, five to eight, de- 



r 



ciduous, linear-lanceolate, acuminate; carpels five to nine, with three 

 seeds in each, and a long straight style, reflexed at the top. 



Hab. On gravelly places on the Australian Alps, irrigated during 

 the summer months by the melting snow. Mount Hotham, Mount 

 Latrobe, and Munyang Mountains, 



Distinguished from C, Nov^^-Zelandice principally by its white flowers 

 and longer leaf-lobes. It is the only known New Holland species. 



11. CRUCIFERiE. 



5. Cardamine laciniata, F. Muell.; perennial, erect, glabrous; leaves 

 nearly all radical, on loug petioles, lanceolate, remotely toothed or laci- 

 niate Or sometimes pinnatipartite ; flowers in the raceme remote ; petals 

 oblong-cuneate, hardly twice as long as the sepals ; silicjuas as well as 

 their pedicels spreading ; style short ; seeds brown, slightly wrinkled. 



Hab. On moist grassy as well as on boggy places, along rivers and 

 creeks ; it often indicates a saline soil. 



6. Cardamine eustj/Us, F. Muell. ; dwarf, glabrous or somewhat 

 downy ; root creeping ; stem thin, upwards naked ; leaves petiolate, 

 pinnatisect ; segments five to seven, ovate or oblong, lobulatc or with 

 a few teeth, the terminal one the largest, the inferior ones narrowed 



Apparently not different from 3/. miHimia^ L, — Ed.
