AUSTRALIAN PLANTS. 145 



Lehm.) and L. eucalyptoldes. The fruits offer very decisive marks of 

 distinctlou amongst the numerous species ; thus they are in L, canus 

 more succulent, shorter, and with a less contracted border, and not of 

 a greenish-brown colour, as in Z. pendalus. In Z. Preissii the hemes 

 are pink, spherical, and of the size of a pea; in i. Exocarpi black, 

 large, ovate; in X. eucaJyptoides oblong, pear-shaped, green, with a 

 yellowish top. All the described species require a careful new disqui- 

 sition, as they are not only parasites of various plants similar to each 

 other, but also of genera of very different Natural Orders. Thus L. 

 eucahjptoides produces, as long as it adheres to Eucalypti or Casmrince 

 (or now also to Vwgilia Capensis)^ long falcate leaves, which, when the 

 plant receives its nourishment from Banksia integrifoUa^ assume an 

 Ovate-orbicular shape, and a very fleshy consistence, whilst the flow^ers 

 become sessile. 



On a former occasion I alluded to the singular circumstance that the 

 genus should be foreign to Tasmania ; although it is here not only am- 



and exists in New Zealand.

97. Sambucus xaw^^oca?7A7,* F. Muell.; arboreous; leaves pinnately 

 three- or five-foliolate or bipinnate, smooth, without stipules ; leaflets 

 lanceolate or ovate-lanceolate, long-acuminate, with exception of the 

 basis sharp-serrated ; cymes with five or seven principal branches ; 

 flowers three- or rarely four-parted ; berries yellow, three-seeded. 



Hab. On the shady moist banks of the Brodribb, Snowy, and Cab- 

 bage-tree Elvers. 



A tree with the habit of the common Elder, and perhaps of equal 

 utility.

98. Diodia (Sect. Eudiodia) reptans\, F. Mueil.; perennial, herba- 

 ceous, much branched ; stems rooting ; leaves ovate, actitish, petiolate, 

 glabrous or covered with short stiff hair, always ciliate; stipular va-

 t This is not a Diodia, but a Nertcra, or closely allied plant, very smular to ^, 

 tetulosa^ Hook. fil. (Fl. N. Zeal. i. 112. t. xxviii.J?.). agreeing with this plant m (lie

 iera ahoald be modified to include several pbats, chiefly ditTering in the strwcture of 

 the calyi-lohe.
