Amongst the specimens of C. pedicellosa and C. colorata col- 

 lected near Perth by Mrs. M. Davis was a single specimen of 

 another species which I at first took for C. 

 Sieberiana, l a species recorded for W. A. by 

 Bentham (1. c.) and later authors. But on 

 comparison of the specimen with Sieber's origi- 

 nal plant (PI. Sieberianæ no. 173) and with 

 other specimens of the same species from Vic- 

 toria (leg. F. v. Müller) and S. Australia (leg. 

 J. M. Black), it soon became evident that it 

 was an undescribed species, although allied to 

 C. Sieberiana. This makes it probable that the 

 records of C. Sieberiana from W. A. need con- 

 firmation. (It reaches as far west as S. Australia, 

 according to J. M. Black, 1. c). The specimen 

 sent had ripe seeds and from these I have 

 grown some plants which have made it possible 

 to give a full description of the species. I have 

 named it in honour of the collector, my friend 

 Mrs. Miriam Davis to whose indefatigable in- 

 terest I owe a good deal of my collection of 

 W. A. plants. 



The plant (see fig. 13) is a much branching 

 succulent, ascending or erect annual. The flowers 

 are placed in dense clusters in the axils of the 

 leaves; sometimes, especially on the branches, 

 the clusters form a spike-like inflorescence. Some 

 of the flowers are sessile and some short-stalked ; 

 the longer pedicels longer than the flower itself. 

 Sepals from an ovate-triangular base tapering 

 into an acute or acuminate apex and with 

 somewhat corrodate margin. Petals' much nar- 

 rower and inconspicuous, linear-lanceolate, acu- 

 minate. Carpels, when ripe, shorter than the adpressed sepals, 

 obtuse with a medium-sized slender style, somewhat inflated,
