This common aird widoly-diffased plant is probably described under many names, bnt it is quite impossible to
identify its numerous forms satisfnctoi-ily by tlreir published descriptions. Sir. Gnnn at one time thonabl that it
might possibly be an introduced rveed, and, from its localities at Hobarton, I was drcKircd to coincide J ilh him ;
but ri-e changed our opinions independently, on iiiiding the plant to be abrmdant along ad the coasts. .As m iA
be expected, the Tasmanian specimens, especially those that inhabit the moist atmosphere near the sea, are frequeritly
mueh more Inxm-iarrt than the Enropean ones. I partieidar-lj paid attention to this point in Tasmania, where I
found small specimens growing hy the roadsides to be allogellrer like European, brrt gradnally on approaclrdrv
the sea-coast the plants became stonter and more hranched, stiffer, and with larger foKage. In shaded spots A
stems lengthen very irruclr, and often lie prostrate, w-ith slender branches two feet long. I t also Tories extremely in
being smooth or pubescent, and in the size and cutting o f tbe leaves ; which in seedling plants are gener-'nUy
pirmaliirarlite, and also frcqnently so at tiro base of old stems ; at other- times they are lobed, entire, or°sciTaté.
I t is r-cnddy kiiorvn from Z . mneifoliam by its slender- habit, rran-ow leaves, and small pods. De Caridode (quoting
Dcsvaiix’ .Torn-iud) gives D ’Eiitrecastcaiix Clianncl as a habitat for L. fo lio s,m , a plant I do not know, but which ft
said to h.ave the pods almost twice as large as those ot L. plscldmm, and therefore Irvice os hn-ge as those of I .
cuneifolUm. I foiuul L. ruderale Jibimclantly in D ’Entrecasteaux Cliamiel.
