In addition to these, the learned Professor admitted the 

 occurrence of micromorphs as regards the corolla of 

 Z. ammophilum. My No. 164 is the typical form of 

 Z. ammophilum ; leaflets elliptical to linear cuneate, entire ; 

 petals white, stamens four, seeds two in a cell, outer skin of 

 • seed rough (not shining). No. 458, Z. ammophilum, var.; 

 petals white, stamens eight, fruits and seed the same as No. 

 164. No. 457, Z. a?nmophilum, var. or new species (?) ; 

 leaflets broadly cuneate, notched ; petals yellow, stamens 

 eight, fruits truncate, rounded at the base, deeply angled ; 

 seeds one in a cell, of an oval shape — the outer skin of the 

 seed is smooth and polished ; a small prostrate annual. It 

 will be seen this form differs from the typical form in — 



(1) Foliage — 164 leaflets entire ... ... 457 leaflets notched 



(2) Colour of corolla — 164 white ... 457 yellow 



(3) Number of stamens — four ... ... eight 



(4) Number of seeds in a cell — two ... one 



(5) Form of seed — almost three angular... oval in outline 



(6) Outer coat of seed — dull and rough ... smooth and polished 



I have supplied Prof. Tate with more material to work upon, 

 and would not be surprised if he decides to raise No. 457 to 

 specific rank. This form being prostrate in its habit, and 

 the smallest of the genus, I suggest as an appropriate name 

 Zygophyllum humillimum. 



Malvaceae. 



Plagianthus glomeratus, Bentham. 

 *Sida intricata, F. v. Mueller. 



Euphorbiaeeae. 



Phyllanthus Gunnii, J. Hooker. A shrub. 



N.B. — Phyllanthus rhytidospermus should be struck off 

 my list of 1898. 



Chenopodiaeeae. 



An examination of Prof. Tate's Herbarium at the Univer- 

 sity has convinced me that the following species in list 1898 

 should be struck off: — 



Atriplex leptocarpum, F. v. M., for which I now assign 



A. angulatum, var., as the correct name. 

 Bassia bicornis, for which B. diacantha seems to be a better 



reference. 



Amarantaeese. 



Ptilotus Hoodii, F. V. Mueller.
