of a somewhat glauco-fuscous colour, the summit being termi- 
nated by an obtuse perforated gland, through which the shortly 
exserted slender tubillus passes, which has a unilabiate termi- 
nation. The pedicel supporting the fructiferous spikelet, which 
in Bridges’s specimen is not fully grown, is 4 lines long, with a 
pair of bracteoles a short distance below : in Anderson’s speci- 
men the pedicel is 10 lines long, the bracteoles being at a dis- 
tance of 2 lines, and the spikelet is double the size of the 
former. It should be remarked that, in Bridges’s plant, a fructi- 
ferous spikelet is found on one of the lower branches of the same 
specimen the upper branches of which all bear male flowers *.

A shrub, from its very elevated locality, probably of low 
growth, with more erect and more slender branches than the 
preceding species, from which it differs in its general appearance, 
in its much smaller bractiform leaflets, and in its achenia being 
hidden by the last pair of involucels. Its branchlets are oppo- 
site, but sometimes two superimposed grow out of each axil : 
these are floriferous, nearly ^ line in diam., with internodes 9 to 
11 lines apart. The peduncles are axillary, 1 to 2 lines long, 
wdth a pair of bracteoles supporting them at their origin ; and 
they bear a solitary male spikelet, which is ovate, 2^ to 3 lines 
long, bracteated at base, with four pairs of imbricated involucels 
briefly conjoined at their base into a sheath, subcoriaceous and 
1 line long ; perigonium somewhat longer than its own involucel; 
staminiferous column twice its length, bearing 5-7 sessile yel- 
low' anthers opening by two pores in their apex. The fructi- 
ferous spikelets are on a distinct specimen : here the peduncle is 
1 inch long, 2-bracteolate a little above the middle, bearing a 
solitary oval spikelet 3 lines long, 2 lines broad; involucels 
broadly ovate, gradually diminishing towards their summits. 
This species is figured in Plate 75 b.
