 long spiral fibres. The specimen in the Tate Herbarium is 

 from Idracowra, Northern Territory. 



Z. crenat-um , F. v. M. Mernmerna (Dist. C). 



Z. Billardieri, DC, var. ammophilum. Farina. Stems 

 procumbent; flowers drooping; petals 4, white, lanceolate, 

 scarcely as long as the sepals; fruit 5-7 mm. long. This form, 

 which is found in many parts of the North and in the Murray 

 district, is the Z. ammophilum, F. v. M., except that the 

 stamens number 8 instead of 4. I have only found 4 stamens 

 in one specimen from Edithburgh, Yorke Peninsula. It 

 seems to me to vary too little from the type to be considered 

 a separate species. 



Sapindaceae. 



Dodonuea microzyga, F. v. M. Windy Creek, near 

 Leigh Creek. A small shrub about 50 cm. high; leaves 

 spreading, leaflets varnished, very sticky; fruits glossy, pink, 

 15-18 mm. long (with the wings), dissepiments remaining 

 attached to the axis; seeds ovoid-compressed, black. 



Malvaceae. 



Sida intricata, F. v. M. Hawker; Leigh Creek; Yunta 

 (Dist. S). 



Plagianthus glomeratus. Marree; Leigh Creek. The 

 petals, which dry yellow, are described in my field-note as 

 "light green, recurved under the calyx and between its teeth; 

 anthers yellow."

FR ANKENI ACEAE . 



Frankewia, the only genus in this family, is a difficult 

 one, owing to the external resemblance of several of the 

 species and to the variation in the number of floral parts 

 which may be often found on the same plant. Even in the 

 usually regular F . pauci flora flowers can be found with 4 

 calyx-teeth and 4 petals. To the somewhat scanty literature 

 of the genus a valuable contribution has been made this year 

 by Dr. C. H. Ostenfeld in his revision of the Western Aus- 

 tralian species (Contributions to Western Australian Botany,
