777 



Zealand and Australian specimens, and contrasted with the true 

 P. ohtusifolius. 



P. ochreatus, Raoul. 



Stem, slender, terete or some- 

 what flattened, the leaves 

 spread, a little branched, inter- 

 nodes longer. 



Leaves sessile, sometimes sud- 

 denly narrowing at the base, 

 but most often half amplexicaul, 

 obtuse or a little acuminate, 

 without point. 



Midrih broad, with many fine 

 longitudinal nerves on each 

 side. 



Ligule* acuminate and thus 

 more narrow at the top than at 

 the base; more constant. 



Fruit with distinct edges and 

 most prominent beak. 



Beak long, much recurved, 

 the stigma not flattened. 



Spike 1 and \\ inches long, 

 slender, cylindrical, interrupted, 

 not very dense. 



Peduncles 2-3 times longer 

 than the spike, thicker than the 

 stem. 



P. ohtusifolius, Mert., & Koch. 



Stem compressed, with rough 

 rounded edges, very much 

 branched. 



Leaves sessile, all more or less 

 narrowing at the base, none 

 amplexicaul, with two distinct 

 and often reddish-coloured 

 glands at the base, with one, 

 sometimes two, distinct nerves 

 on each side of the midrih, but 

 far distant from it, near the 

 edge; no intermediate fine longi- 

 tudinal nerves. 



Ligule broader at the top 

 than at the base, and thus in- 

 fundi):)uliform or cup-formed, 

 very deciduous without chang- 

 ing in fibres. 



Fruit nearly without edges, 

 slightly keeled, oblique, elliptic. 



Beak short, with flattened 

 stigma. 



Fruit-hearing spike \-\ inch 

 long, thick, cylindrical, and very 

 dense, compact, not interrupted. 



Peduncles of the same lenirth 

 or shorter than the spike, the 

 same thickness as the stem or 

 thinner.
