146 Alfred J. Ewart : 



likely to appear at various points of the lower reaches of the river 

 after floods. 



Lamarckia aurea, Moench. " Golden Lamarckia." (Gramineae). 



Moodemere, North Rutherglen, Murray River. It is growing 

 in unusual abundance owing to the moist season, G. H. Adcock, 

 November, 1916. 



The grass is a native of Europe, Asia and Africa, and was first 

 recorded in 1878. It has only a very slight pasture value. 



Lathyrus angulatus, L. " Angular Pea." (Leguniinosae), 



Harcourt, C. French, jnr., November, 1916. 



This plant, a native of Europe, is abundant at Harcourt, and 

 has probably existed as a naturalised alien in Victoria for some 

 time, but has been overlooked on account of its inconspicuous char- 

 acter and resemblance to a Vetch. It is now growing in all culti- 

 vated land in the district; stock do not seem to eat it readily. It 

 is not recorded as a poisonous plant, but is •worthy of investigation. 



Lavatkra arborea, L. "Common Tree Mallow." (jMalvaceae). 



lona and railway enclosure, Garfield, J. W. Audas, 22/11/1915. 

 A new locality for this introduced plant. It is a native of 

 Europe. 



Lepidium rudekale, L., var SPINESCENS. (Cruolferae). 



Camperdown, Victoria, per G. H. Sinclair, March, 1916. 



This spiny form of L. ruderale has the smaller branches developed 

 into thorns, more irregular branching, the leaves reduced in size 

 and the pods with hardly any notch on top. It was queried by 

 Bentham as a variety spinescens of L. ruderale, and was recorded 

 from South Australia. It is questionable, however, to what extent 

 the two forms are related, as the spiny habit of the variety is very 

 different from that of typical forms of L. ruderale. 



Lrpidium virginicum, L. " Virginian or Wild Peppercress." 

 (Cruciferae). 



Ashburton, Victoria, W. B. Wilson, June, 1915. 



A native of North America. This species is very close to L. 

 ruderale, and cannot be distinguished from it unless both the 

 flower and fruit are available. The petals are present, and the 

 seeds are minutely margined in L. virginicum.
