 about 8 to 10 squarrose flowers. Flowers 4 to 4^ mm. long or 

 with mature fruits attaining to 6 mm., blunt-angled. Perianth

16. J. lamj^ocarpus, Fr. Buch. 



A somewhat casspitose perennial. Stems 5 to 25, rarely 45 cm. 

 high, either erect and terete or ascending and compressed. 

 Lamina of the leaf terete or compressed, often curved, perfectly 

 septate and one-tubed. Inflorescence mostly with numerous 

 flower-clusters, anthelate, the branches oblique-erect, the ultimate 

 ones often squarrose. Flowers few or rarely numerous in the 

 cluster, 2|^ to 3 mm. long. Perianth segments of equal length, 

 mostly all acute, the inner ones rarely obtuse. Stamens 6. 

 Fruit longer than the perianth, ovate, prismatic-pyramidate, 

 shortly mucronate, shining, black or brown, rarely rust-coloured 

 or greenish. 



Common in Europe and Asia, less common in North America, 

 Northern Asia and New Zealand. No Australian localities have 

 been hitherto recorded for this species, but it is common in 

 swampy places in the Port Jackson district; and we have also a 

 specimen from South Australia. We have to thank Prof. 

 Buchenau for the determination of our specimens.
