Cyperus Novae-TIollandiae : One of the larger kinds, 
rather coarse. Not common, around clay waterholes in 
gum-topped Box ( Eucalyptus hemiphloia ) country on 
slate with indifferent drainage. 
Cy perns ferax : Only a few of this species are found 
here and there around clay waterholes in slate country. 
Cyperus Bowmanii: This is often met with in partly 
cleared forest with soil of an open character from 
trachyte. 
Cyperus umbellatus : Very common, usually associated 
with C. fulvus on calcareous sandy loam soils from amphi- 
bolitic rocks on low ridges. 
Cyperus lucidus : The most common of the larger 
kinds of this genus. Found on the banks of most of the 
larger water courses where it contests the soil site with 
Xerotes longifolia ; found in both exposed and well shel- 
tered situations. 
Kyllinga monocephala : This is not a very common 
plant although found on a fairly wide range of soils, from 
andesitic loams to conglomerate gravels. 
Heleocharis cylindrostachys : Common. Semi-aquatic, 
found on creek beds and clay waterholes. 
Fimbristylis monostachya: Found in numbers on the 
lower slopes in well sheltered bloodwood ( Eucalyptus 
eorymbosa) — mahogany ( Tristania suaveolens) forest, soil 
from porphyry or trachyte detritus. 
Fimbristylis diphylla : The most widely distributed of 
all the family. On open black soil flats (some years ago) 
as much as an acre of ground would be occupied by this 
species, some 2 feet high. In wet grass on sandy ridges 
plants 6 inches high are numerous. With the exception of 
granite hills and badly drained flats, all types of soil 
favour this species. 
Fimbi'istylis microcarya : Common in well sheltered 
bloodwood ( Eucalyptus eorymbosa) and Bose She-oak 
(Casuarina tondosa) country on low hills, soil derived 
from quartz-trachyte and trachyte. 
Fimbristylis setacea : A few patches of this are met with in 
second growth forest, soil a sandy loam. 
Fimbristylis cyperoides : Has a fairly wide range as 
regards the type of forest association it favours. It is met 
with in narrow leaf Ironbark ( Eucalyptus crebra ) country 
on soils derived from andesite, in Sugar Gum ( Angophora 
lanceolata) country on soils from rhyolite. In the latter, 
however, much smaller plants. 
Fuirena glomerata: Fairly common in most seasons. 
Favours a moist, sandy soil, where it grows up to 2 feet 
high.
