Range that this plant was met with, growing in the thick 

 mulga scrub.] 



AizoACEAE. — Trianthema aystcdlina, VahL Lambinna 

 Soakage ; Wantapella Swamp. [Seen on country subject to 

 flooding.] 



PoRTULACACEAE. — Galandvinia ptychosj)erjua, F. v. M. 

 Glen Ferdinand. 



Caryophyllaceae. — Polycarpaea conjmhosa, Lam. Coon- 

 gra Creek. [Only observed this plant in the one locality.] 



Cruciferae. — Stenopetalum lineare, R. Br. (?) Between 

 Flat Rock Hole and Moorilyanna Native Well. This may 

 be a small hairy form of this species, of which it has the^ 

 flowers and short pedicels. The leaves are mostly radical,, 

 pinnatisect with narrow lobes and more or less tomentose with 

 branched hairs. The specimens are only about 12 cm. high. 

 S. nutans, F. v. M. Glen Ferdinand and Moorilyanna Native 

 Well. [Growing in small colonies.] Blennodia trisecta, 

 Benth. Ninety miles west of Todmorden Station. Pods more 

 swollen than usual. [Often met with in dry watercourses.] 

 B . canescens, R. Br. Near Todmorden Station ; Tietkens' 

 Birthday Creek. [Where a shower of rain had fallen a week 

 or so previous to our visit quite a quantity of this plant had 

 sprung up from the sandy soil.] 



Menkea hispidula, sp. n. (tab. Ixx.). Herha annua 

 nana fspeciminibus nostris 2-3 cm. altis), omnino pilis 

 patentihus instructa, foliis lineari-ohlongis ohtusis integris vel 

 paucidentatis radicalihus in pefiolum angusfatis, petalis lutein 

 sejJaJa p)atentia triente superantihus, sdicidis ovoideo-glohosis- 

 pubescentibns pedicello paulo hreviorihus. Fifteen miles west 

 of Indulkana Springs. This species differs from all others in 

 its minute size and stiffish spreading hairs. The pods probably 

 resemble those of M . sphaerocarpa in shape, but as none are 

 quite ripe and the specimens are in poor condition, it is impos- 

 sible to say to what extent they may be compressed or 

 globular. Two similar specimens are in the Tate Herbarium 

 labelled "Capsella cochlearina, var. ochranfha, from the 

 Upper Arkaringa, Helms, 20/5/91." They certainly do not 

 belong to Capsdla, as the ovary has no septum and contains 

 over 60 ovules. One of our specimens (gathered July 12, 

 1914) has a ripening capsule with the numerous seeds, 

 arranged as in Menkea. Apart from the number of seeds, 

 these specimens bear a considerable resemblance to the descrip- 

 tion of Capsella vd.losula, also collected by Helms on the 

 Arkaringa Creek and described as a new species by Mueller 

 and Tate, but of which the Tate Herbarium contains na 

 specimen. In the report of the Elder Expedition (Trans. 

 Roy. See, S.A., xvi., 335) both C. cochlearina, var^
