254 THE TASMANIAN FLOBA. 



13. C. BiCHENOViANA, Boott. Stems 1-2 feet. Leaves as long as stems. 

 Spikelets 7-14. Males terminal, in a cluster, 1| inch long. Female, or mixed 

 spikelets, dispersed lower down, shortly stalked, each subtendbd by a leaf-like 

 bract. Glnmes dark brown, obtuse, with a protruding midrib. Mature utricles 

 not seen. 



Woolnorth. Inserted from record only. Doubtful. 



14. 0. LONGiFOLiA, M. Br. Stems 1-2 feet. Leaves flat, about the same 

 length. Spikelets 6-20, on rather long stalks, often nodding. One or two 

 terminal ones male, lower ones female, but usually tipped wdth some male flowers. 

 Utricles loosely imbricate, 2-3 lines long, 3-angled, tapering into a rather long 

 neck. C. lorigihrachiata, Boeck. 



Common in damp situations ; also South and Bast Australia. 



15. C. PSEUDOCYPEBus, Linn. Stem 3-angled, 2-3 feet. Leaves flat, as long as 

 the stem. Spikelets about 2 inches long, few drooping, on long stalks, towards 

 the apex of the stem, the terminal one male. Utricles spreading, longitudinally 

 ribbed, ovate, 2-3 lines long, the neck long and slender. Cfascicularis, Sol. 



Huonville, Derwent above New Norfolk, and numerous other river-banks. 

 Extra-tropijcal Australia, New Zealand, and temperate climates throughout

Flowers solitary, or few or many together in dense distichous clusters or 

 spikelets. Each flower contained in a bract or glume, with usually a smaller 

 glume or pale on its inner side. There are usually two or more empty glumes 

 below, and rarely one or more above, the flower or flowers of a spikelet. Periaath 

 none, or perhaps represented by small scales, termed lodicules, below the pistil. 

 Stamens generally 3, with versatile pendulous anthers. Pistil simple, the solitary 

 ovule intimately blended with the ovary. Styles usually 2, with feathery 

 stigmas. Fruit usually a mealy grain or minute utricle. Leaves with a split 

 sheathing base and a ligule at the junction of the lamina. Inflorescence various, 

 but the spikelets generally numerous. 



What is here termed the flowering glume is in some works called the 

 lower pale, and the smaller one the upper pale. All Tasmanian forms 

 are herbaceous, and the fruit grain-like. Some tropical forms become 

 almost of the character of trees, and the fruit is a berry. In Sporo- 

 bolus the fruit is an utricle, from which the seed is usually expelled at 

 maturity.
