Lepidium oxytrichum — In 1852 F. Mueller gave the name 

 fLepidium papillosum to a new species collected hj him in South 

 Australia.* This was characterised by a dense clothing of white 

 clavate papillae on the stem and branches, and by a narrow 

 Btraight-sided sinus at the apex of the silicle. In a second 

 -account published in 1879 he described the stem and brunches as 

 l)elng covered with very short spreading turgid, almost vesicular 

 liair.t L. papillosum is represented in the Kew Herbarium by a 

 type-specimen from Crystnl Brook, South Australia, and by two 

 plants collected in New South Wales and South Australia by 

 Cunningham and Wheeler respectively. 



The plants described by ThellungJ under this name belong to a 

 ■^listinct species which has the stem and branches densely hirsute 

 with slender linear-subulate hairs, and a triangular sinus at the 

 apex of the silicle. For this species the name Lepidium oxy- 

 trichum is now pro2)osed. Its synonymy and distribution are as 

 follows : — ■
