20 FLORA OF TASMANIA. [Cruciferce. 
linear lobes of the upper cauline leaves; the latter character is shared by the radical leaves of the var. tenuifolia. 
Even the different Ta-mauian varieties may all be found amongst our European and Arctic forms.

Hab. Throughout the Island, abundant in many localities, from* the sea-shore to 4000 feet elevation.

Distrib. South-eastern and Western Australia, New Zealand, Antarctic Islands ; abundant throughout 
Europe, North America, in the hilly regions of the tropics, and in the Pacific Islands. 
There are no limits to the variations of this protean plant ; I have studied it in a thousand forms, from all 
the wonder is, not that different forms of the same species >honhl inhabit both countries, but that exaetlv tin- 
same forms should occur in each. The most remarkable and onh tangible ihltercnees amon^i the I e-niaiinii 
specimens are the comparative breadth of the pod and length of the style; for those of habit, sizes of the (lowers, 
form and cutting of the leaves, and number of the leaflets, etc., afford no characters at all. These differena - m 
the pods are so great, that I have often felt inclined to class several of the varieties with C. pratetms, 
Sowers are common amongst them; but on the whole I think it better to leave them as thej arc, though 
in a ven un-ati-lYa . in -t te, and to recommend the subject to the attention of the colonial botanist; meanwhile 
all the smaller forms of naj b< provisi rnallj referred to O. terutta. I find amongst Euro- 
pean specimens of C. hirsuta, forms that are in every respect similar to the Tasmanian ones.
