spikelets. Spikelets about 1 line long and broad, the glumes acutely acuminate. 

 Perianth-segments 6, under ^ line long, all nearly equal and quite glabrous or 

 minutely ciliate. Ovary glabrous. Styles 2 or 3, free from the base or nearly 

 so. Fruit about i line long, the pericarp readily splitting into 2 or 3. 



Hab.: Gulf of Carpentaria, E. Brown; Daintree River, Fitzalan. 



As observed in several other Eestiaceee some diseased inflorescences have larger flowers filled 

 with the black granules of a fungus. — Benth. 



3. I., spathaceus (spathe-like), R, Br. Prod. 250; Benth. IH. Austr. Tii. 

 ■236. Ehizome unknown. Stems erect, 2ft. high or more, divided into few rigid 

 :and erect or more numerous slender somewhat flexuose branches. Sheathing 

 ssoales closely appressed, acute or shortly acuminate. Spike-like panicles narrow 

 and not much branched, the small spikelets numerous and clustered along the 

 branches. Males in the specimens seen too imperfect for examination. Female 

 spikelets ovoid, about 1 line long. Glumes acutely acuminate, rather spreading. 

 -Perianth-segments 6, narrow-lanceolate, acutely acuminate, all glabrous. Style- 

 toanches 2 or 3. Pericarp thin. — L. desertus, F. v. M. Fragm. viii. 93. 



Hab.: Gulf oi Carpentaria, B. Broion. 



The majority of specimens examined diseased with the inngua.^Benth. 



4. L. Schultzii (after M. Schultz), Benth. Fl. Austr. vii. 237. Ehizome 

 shortly creeping, densely woolly, emitting numerous slender almost filiform much 

 branched barren stems under 1ft. high, and rigid erect simple or slightly branched 

 :fiowerin.g stems attaining 2ft. or more, densely and softly cottony-villous as well 

 as the rhachis of the panicle. Male spike-like panicle slender, narrow, not much 

 branched, the young spikelets narrow, 1^ to 2 lines long. Glumes acuminate with 

 scarious margins. Perianth-segments 5 or 6, the outer ones narrow and 

 acuminate, the inner broader, thinner, and almost obtuse. Stamens 3. Females 

 unknown. 



Hab.: Cape York Peninsula. 



4. HYPOL^NA, E. Br. 



(From hypo, under, and chlaina, a cloak.) 

 . (Calorophus, Labill. \ Calostrophus, F. v. Muell.) 

 Flowers dioecious, the males several together or rarely solitary, the females 

 solitary, in spikelets with imbricate glumes and no bracteoles. Male flower: 

 Perianth-segments 6, narrow, glume-like or thin. Stamens 3, filaments filiform ; 

 ■ anthers 1-celled. Female flower : Perianth-segments 6 or 4, short broad and 

 very thin, almost hyaline. Staminodia B or none. Ovary 1-celled, with 1 

 pendulous ovule ; styles or style branches 2 or 3, filiform, stigmatic from below 

 the middle. Fruit a small ovcid or obovoid indehiscent nut. — Stems usually 

 muck-branched and often flexuose, leafless except the sheathing scales which are 

 persistent. Male spikelets either solitary or 2 together within distant bracts 

 along the branches, or several in a terminal panicle. Females solitary or 2 or 3 

 together at the end of the branches. 



Besides the Australian species of which one is also in New Zealand, there are several from 

 : South Africa. 



Sect. I. Calorophus. — Wale spikelets solitary or 2 together, 1-sessile, the other shortly 

 pedicellate, within distant floral bracts. 



Male spikelets several-flowered. Female spikelets terminal or sessile, 2 to 



3 lines long • 1. H. lateriflora. 



Sect. II. Euhypolsena.— ilfaie spikelets all pedicellate in a small panicle. Female 

 ^spikelets terminal solitary or in clusters of 2 or 3. 



.■Style-branches longer than the entire part . , 2. H. fastigiata.
