Despite the f;ict that a very large tract of the country traversed 

 by the Eider Exploring; E.xpedition liad been previously investi- 

 <>-ated for its botany, the collection made by Mr. Richard Helms, 

 the Naturalist to the Expedition, assisted by his colleagues, 

 contains a relatively large number of new species, has consider- 

 ably augmented the list of West Australia plants and furnished 

 material for the better definition of some species hitherto incom- 

 pletely described. 



The numbers of new species are for South Australia one {Cap- 

 sella villosula), and for West Australia eighteen. 



The addition to the South Australia flora is one {Cyperus laevi- 

 gahis), in addition to the new species. 



The additions to the list of species inhabiting the Province of 

 West Australia, less those descriptively new, are the following 



thirty-five : With two exceptions, Canthiutn oleifolium and 



Schoenus aphyllus, all are characteristic Eremian plants having 

 their metropolis in the dry interior of South Australia ; Kenneclya 

 prorepens, Anthoholus exocarpoides, Tecoma australis, and 

 Briachne scleranihoides are saxatile species of the basin of the 

 Upper Pinke, extending to the botanical outlier of Barrow 

 Rann-e • the low-land species, Fhyllanthus laaunarius, Polycmyaea 

 Indtca', Euxolus MitcheUi, Brachysema Ghamhersi, Acacia patens, 

 Didiscus glaucifolius, Podolepis canesoens, Relichrysimi Ayersi, 

 Solanum ' Sturtianum and Teucrium grandiusculum extend be- 

 yond the confines of South Australia to Cavenagh and Barrow 

 Rano-es • but Stenopetalum velutinum, Euphorbia eiythrantha, 

 Thryptomene Maisonneuvii, Ilelipterum Fitzgibboni, II. stipitatum, 

 Dicrastylis ochotricha and Eremophila Gibsoni reach into the 

 Victoria Desert ; whilst Dodonaea filifolia, Saponaria tubulosa, 

 Chenopodium rhadinostachyum, Muehlenbexkia polygonoides, Gly- 

 cyrrhiza psoraleoides, Loranthus gibberulus, Ilelipterum Troedeli, 

 Daeviia Kempeana, Solanum eremophila, Teucrium sessiliflorum 

 and Eremophila Paideyi extend to Fraser Range or a little 

 beyond.
