P. oclirentns Raoul. 



Choix de plantes de la Nouvelle Zélande, — in Annals des sciences nat III, 

 Bot. II, 1844, 117. — Fig. 30. 



The description of Raoul refers to a plant he had gathered in »la presque ile 

 de Banks» (PeninsulaBanksiana 

 in the south island). It has 

 greyish-green leaves with very 

 obtuse, almost truncate or 

 even a little etnarginate, canali- 

 culate apex, seldom endowed 

 with a nearly imperceptible 

 blunt point ( foliis linearibus 

 apice rotundatis truncatis v r . 

 emarginatis viridibus»: Raoul); 

 peduncles rather elongated, 30 — 

 100 mm ; styles straight ; stigma 

 covering their upper surface. 



Anatomically the stem is 

 distinguished by the 2 — 3-celled 

 pseudo-hypoderma along which m- 

 a complete circle of mechanical 

 strands are arranged, Fig. 30, 

 A. Interlacunar bundles are 

 wanting. The endodermis con- 

 sists of O-cells and the central 

 cylinder has a median channel 

 and two lateral ones (oblong 

 type). The subepidermal strands 

 still appear in the peduncle but 

 the endodermis has disappeared 

 and the two median bundles run 

 separately conducted by 2 — 6 _,. OA . „ „ . „ . „ ,

Distinguished from this, but probably of common origin a proper Australian race 

 appears with repeatedly furcate ramification upwards according to the type B (fig. 2). 

 Leaves more brovvnish, more tapered towards the top, in the branches always more 

 or less cuspidate and usually with stronger mechanical strands than has the true
