224 THE TASMANIAN FLORA. 



9. J. MARiTiMus, Lam. Very similar in habit to J. communis, but rather more 

 rigid, and the leaves extended into cylindrical stem-like laminse, except the outer 

 ones. Stems 2-.3 feet high, the erect bract sometimes very short. Inflorescence 

 dense to very loose. Perianth dark brown, about 1^ line long ; outer segments 

 acute, inner ones obtuse Stamens 6. Filaments short and broad. Capsule 

 about as long as the perianth, dark, shining, and rather acute. , 



Common in salt marshes. It occurs almost throughout Australia. Common 

 to most temperate localities of the world. Fl. Oct.-Nov. 



10. J. PEISMATOCARPUS, J?. Br. Tufted, on a creeping ba^e. Leaves mostly at 

 the base of the stems, sheathing, the laminse cylindrical, divided inside by pithy 

 septa. Stems 1-2 feet high, slightly compressed. Inflorescence terminal, but 

 appearing lateral on many stems by the subtending bracts appearing continuous. 

 Flowers clustered in heads, in a rather loose compound panicle. Perianth- 

 segments narrow, acute, about 1^ line long. Stamens generally 3. Capsule with 

 prominent acute angles. J. holoschcenus, R. Br. 



Very common in damp situations. Throughout extra-tropical Australia. 

 Fl. Nov.-Dec. 



11. J. CAPILLACBDS, Sook. A Small plant, densely tufted, on a creeping base. 

 Leaves slendei", filiform, dispersed on the stems, the bases shortly sheathing, the 

 laminse cylindrical and septate, except where very small, |-4 inches long. Stem? 

 erect, at least in the upper portion, t,-3 inches high Flowers few together, in 

 clusters or solitary, terminal, but often 1 or more cluster below the terminal one. 

 Perianth -segments about 1 line long. Stamens usually 6. Capsule with 3 

 obtuse angles, pointed, usually exceeding the perianth. J. stipulatus, Mey. 



Longley, Zeehan ; common in many wet pastures, but overlooked. It occurs 

 in New South Wales and Victoria, also in New Zealand. Fl. Nov.-Dec. 



Oeder LXXXIL—TYPHACE^. 



Flowers unisexual, in dense heads or spikes. Perianth none, but its place 

 taken by numerous hairs or scales surrounding each flower. Male flowers 

 clustered above the female, each consisting of 3 or fewer stamens; female 

 flowers consisting of a simple 1-ovuled carpel, tapering into the style. Fruit a 

 small 1-seeded nut. 



The order has but few genera, but is distributed almost throughout the world. 



k 



TYPHA. 



Flowers in dense cylindrical spikes, the males forming a mass distinct above 

 the females. 



The one species found in Tasmania has nearly as wide a distribution as the 

 order. 



T. AWGUSTIFOLIA, Limi. Stems from a creeping rhizome, erect, often several 

 feet high, cylindrical, ;i-f inch diameter. Leaves sheathing, flat, longer or 

 shorter than the stem, J^-i inch broad. Female spike brown, velvety, 3-12 

 inches long, l-l inch diameter; male spike close above or removed from the 

 female, in a shorter, narrower, spike. 2'ypha bromnii, Kunth : T. muelleri, 

 Eohrb. r -yi 



Common in water ; also throughout Australia. Fl. Dec. 



Order 'LXXXlll.—LEMNACE.^. 



Small floating or submerged plant, without distinct stem or leaves, expanding 

 into leaf -like fronds, with usually a flliform descending root. Flowers seldom 

 ■forming, consisting of 1 or 2 stamens and an ovary enclosed in a bract formed on
