* Mueller omits Geococcus in his Second Census, and explains in his key to the Syst. 
of Vict. PJ. that he regards it as a stemless condition of Sisymbrium cardaminoides. 
Prof. Ewart proposes to keep it as a distinct species in Proc. Roy. Soc. Viet. xx, 79, pl. 
x and xi (1907). See also ‘* Dimorphism, in two South Australian Cruciferous Plants,” 
by Prof. R. Tate, in Z’rans. Roy. Soc, S.A. (xxii) 1898. 
7 In the arrangement of the genus Lepidium we have followed the monograph of Dr, 
A. A. Thellung, ‘‘Die Gattung Lepidium,” published in Zurich in 1906, with the 
exception of L. phlebopetalum, which we have united with L. rotundum, and which 
Thellung keeps a distinct species. The true L. rulerale L is not an Australian plant. 
The species named L. ruderale by Hooker in the ora 7'asmanica, and by Bentham in 
the Mora Australiensis, is split up by Thellung provisionally into the following ten 
species :—L. puberulum Bunge, pseudo-ruderale Vhell., hyssopifolium Desv., sagittwlatum 
Thell,, pseudo-tasmanicum Thell., Desveauxii Thell., ambianum F.v.M., tasmanicum 
Thell., Aschersonii Thell., and’dubinm Thell., only four of which scem to be New South 
Wales plants. Prof. Thellung admits that the Australian material at his disposal was 
‘scanty, and that a thorough examination of the section Pseudo-Ruderalia with richer 
material will probably result in considerable alterations. The radical leaves of 
Lepidiums wither away so early in the summer that they are rarely collected, though 
they are of importance in Thellung’s classification. We use this opportunity to draw 
. the attention of collectors to the necessity of collecting Lepidiums early in the spring, 
with the r.dical leaves, and later in the season again with ripe fruits.
