specimens I found them to be 6 only — 3 opposite the 3 glands 

 at the. base of the 3-celled ovary and 3 alternate with the 

 glands. Thus in this species the number of stamens is twice 

 as many as the ovary-cells, and does not depend on the number 

 of sepals and petals, which is 4. The anthers are almost 

 globular, and the filaments are slightly dilated towards the 

 base but not winged. The glands are fleshy, ciliolate at 

 summit, quite distinct from each other, united very slightly 

 to the base of the ovary, and doubtless represent the disk. 

 The yellow petals scarcely exceed the sepals, both being about 

 2 mm. long. The ovules are 2 in 'each cell, suspended, with 

 a ventral rhaphe, and a superior micropyle. Tate in his 

 Flora, and Koch in the MS. note to his specimens in the Tate 

 Herbarium, state that the number of stamens is 8, but a 

 careful examination of the material — from Lake Torrens Plain 

 (Tate) and Mount Lyndhurst run (Koch) — proves the number 

 to be only 6. The same is true of Tate's specimens from 

 Crown Point, Finke River, N.T. The lower stem-leaves are 

 often entire. 



Z. Billardieri, DC, var. ammophilum, J. M. Black. 

 Tarcoola. Petals white, shorter than sepals; stamens 8; fruits 

 small. 



EUPHORBIACEAE. 



Euphorbia australis, Boiss. Near Mount Bayley, about 

 5 miles north of Beltana (H. W. Andrew). This appears to 

 be a rare or at least localized species, and in this respect it 

 contrasts with the ubiquitous E. Drummondii. 



Adriana (1) Hookeri, (F. v. M.) Muell. Arg. Ooldea 

 Soak, where it is known as "Water Bush," owing to the 

 belief that water may be struck below the soil where it grows 

 (J. M. B.). This seems to be a different species from A. 

 tomentosa, Gaudich., which was found by Capt. White in 

 January, 1917, at the Ooldea condensers — a shrub only 60 cm. 

 high, with broad leaves (3-5 cm. long by 2-3 cm. broad), 

 cordate at base, and often 3-lobed. The shrub at the Soak 

 is over 1 m. high, has oblong-lanceolate leaves 3-5 cm. long 

 and 1-2 cm. broad, not 3-lobed or cordate at base, but 

 coarsely crenate and narrowing abruptly into the petiole. The 

 styles are very shortly united at the base, but the leaves are 

 too large for typical A. Hookeri. In both plants the female 

 flowers are almost solitary. F. v. Mueller united A. Hookeri 

 with A. tomentosa. The specimens from Ooldea Soak agree 

 very closely with some in the Tate Herbarium collected by 

 R. Helms in the Victoria Desert, W.A., and placed under 

 A . tomentosa.

 (per E. H. Ising). A Calif ornian weed, strongly scented and
