234 THE TASMANIAN FLORA. 



its base. Flowers shortly stalked. Perianth-segments about If line long, 

 narrow, acute. 



Muddy Plains, George's Bay, Swanport, Bvandale, Circular Head, &c. ; also in 

 Victoria, South Australia, and New South "Wales. 



2. L. TASMANICA, Hook. Stems from a creeping rootstock, erect, but slender 

 and much divided, 1-2 feet long in open situations, many feet long among under- 

 growth and in scrub ; the surface rather coarsely nodulated ; with a few 

 closely appressed or rather loose bracts at intervals, about \-^ inch long, 

 generally with a short subulate lamina. Flowers in small, generally few-flowered, 

 clusters, at intervals towards the ends of the branches, each cluster with a 

 loose bract at its base. Perianth-segments narrow, acute, about 1 line long, 

 except the outer segments of the male flowers, which are much shorter L. 

 paniculata, F. v. M. 



Common in wet heaths. It occurs also in Victoria. 



The elongated form, with few flowers in the clusters, is often referred to 

 as var. Inxa. In the field it is not separable from the type. 



2. HYPOL^NA. 



Perianth-segments 6, rarely 4, equal, or rarely the outer ones shorter. Ovary 

 1-celled, with 1 pendulous ovule. Flowers dioecious ; the males usually in 

 spikelets, many-flowered, with over-lapping glumes ; females solitary. 



A small genus, spreading from South Africa to New Zealand. 



Spikelets solitary, about 2 lines long. 



Spikelets terminal, 1-flowered ... ... ... 1. H . longissima. 



Spikelets sessile, at intervals along the branches ... 2. H. lateriflora. 

 Spikelets racemed or panicled, or if solitary, 3-4 



lines long ... ... ... ... ... ... 3. H.fasligiata. 



1. H. LONGISSIMA, Benth. Stems much divided, slender, wiry, tangled, and 

 climbing among the shrub. Sheaths closely appressed, j-| inch long, with a 

 narrow, flat, spreading lamina, 2-4 lines long, that soon falls. Male spikelets 

 few, lateral, 1 -flowered, surrounded by 2 very short glumes ; perianth about 1\ 

 line long, the outer segments much shorter than the inner ones. Female 

 spikelets narrow, solitary, terminal, 1-flowered, perianth of 6 or 4 equal segments, 

 about 2 lines long. Nut about 1 line long. Calorophw elongatus, Lab. ; 

 Calostrophux elongatus, F. v. M. 



Mount Wellington, Henty River to Mount Dundas, Mount La Perouse, Arthur 

 River, Circular Head, &c. 



2. H. LATERIFLORA, Benth. Stems slender and much-branched, generally 

 flexuose, especially when short, from a few inches to many feet long. Sheaths 

 closely appressed, mostly \ inch long, with a persistent, recurved, spreading or 

 erect, slender point, about 2 lines long, a tuft of woolly hairs generally at the 

 orif\ce Spikelets all sessile, solitary or 2 together, in the distant bracts. Males 

 about 2 lines long ; perianth about 2 lines long, segments all equal. Females 

 narrow, about 2-3 lines long ; perianth of 4-6 narrow, nearly equal, segments, the 

 innermost longest. Nut nearly globular, about ^-| line diameter. Calorophus 

 elongatus, Hook. " Fl. Tas." ; Calostro'phm lateriflorus, F. v. M. 



Very common in wet heaths and on mountain-tops. It occurs also in 

 Queensland, New South Wales, and Victoria. It extends also to New Zealand. 



8. H. FASTiGiATA, R. Br. Stems erect or sub-erect, much-branched, 6 inches 

 to \\ foot high, obscurely striate, pale. Sheathing scales dark brown, closely 

 appressed, \-^ inch long, with a spreading or, more often, erect point. Male 

 .spikelets numerous, in a terminal, nodding, loose panicle, each about 2-3 lines
