seedpods remained.] Acacia ciharia, F. v. M. Officer Creek, 

 Indulkana Springs, and Everard Range. In flower only; 

 phyllodia 9-13 cm. long. [Not nearly so plentiful as the 

 common mulga (A. aneura).^ A. cloraioxylon, Cunn. 

 Moorilyanna Native Well. Rhachis of flower-spike golden- 

 pubescent. [Large bushes up to 15 feet high grew under the 

 sheltered south side of the huge granite boulders ; in full 

 blossom.] There are also specimens of a species near .4. 

 ci/perojjhyUa, F. v. M., gathered in the Musgrave Ranges, but 

 the phyllodes are more slender and the branches lack the 

 reddish tinge of the "Red Mulga." There are neither flower 

 nor fruits. .4. strongylojjhylla, F. v. M. Everard Range. 

 [This beautiful shrub was only met with in the Everard 

 Range, from 3 to 8 feet high; they were shapely bushes, 

 covered in golden blossom.] A . tetragonophyUa, F. v. M. 

 Thirty miles west of Oodnadatta and 20 miles east of Mus- 

 grave Ranges. [Although generally dispersed, it is not a 

 common shrub.] A. salicina, Lindl. "Native Willow.'" 

 Oodnadatta. [Fine trees of this beautiful drooping species 

 were met with all through the country.] .4. aneura^ 

 F. V. M. ( ? ) Flat Rock Hole. In leaf only and the phyllodia 

 unusually narrow (scarcely exceeding 1 mm. in breadth). 

 "Round-leaved Mulga" is the local name. [I am firmly of 

 the opinion that this is a distinct form from the common 

 mulga. The two are often intermingled, but many isolated 

 colonies of the round-leafed form were met with. I am sure 

 there are three, if not four species of mulga in the north-west 

 country, but unfortunately hardly any were bearing flowers 

 or pods.] 



Geraniaceae. — Erodium cygnorum, Nees. Glen Fer- 

 dinand and 15 miles west of Indulkana Springs. [Owing to 

 the dryness of the country very little "geranium" v/as seen; 

 in some places much dried and blackened remains of this 

 plant indicated a thunder-burst some time before.] 



Zygophyllaceae. — Zygophyllum iodocarptim, F. v. M. 

 Glen Ferdinand. [Only met with this plant once in the Mus- 

 grave Ranges.] Z. fruficulosiim, DC. East of Everard 

 Range. Petals only 4 mm. long, fading from yellow to white. 

 [Not a common plant; growing on the sandy soil.] Z. apicv- 

 latum, F. V. M. Indulkana Springs. Tribi/lus terrestris, L. 

 Glen Ferdinand. 



Rutaceae. — Eriosfemon liiiearis, Cunn. Between Mooril- 

 yanna Native Well and Everard Range. [Only met with the 

 once; a good-sized bush, covered in blossoms.] 



EuPHORBiACEAE. — Euphorhia Brummondu, Boiss. Fif- 

 teen miles west of Indulkana Springs ; 40 miles west of Oodna- 

 datta and Glen Ferdinand. [Grows very close to the ground;
