colonies, and is a cosmopolitan grass in addition. In New South 
Wales it is found in most parts of the Colony. The following note 
from a correspondent from Myall Plains, near Jerilderie, explains one 
of its habitats :— 
“Only growing on some land that was cleared and burnt off last 
January, and only in the stump holes and ashes where the trees were 
burnt, and as thick as it can grow. It is quite unusual for grass to 
grow here for several years where large trees or heaps of wood or 
scrub are burnt, but this grass seems to come up at once, and do well 
where the most ashes are found. It grows so high and rank that you 
can trace where every portion of the tree has been burnt.” 
47. HIEROCHLOE. 
Spikelets with one terminal hermaphrodite flower and two male 
flowers below it, in a pyramidal or narrow terminal panicle, the rhachis

Glumes six, thinly scarious; two outer acute, keeled, with a more or 
less distinct short nerve on each side; third and fourth obtuse or emar- 
ginate, the keel sometimes produced into a short awn, each enclosing 
a narrow palea and three stamens; fifth shorter, broad, obtuse, five- 
nerved, the keel rarely produced into a short point, enveloping the 
sixth which is narrower with a central nerve or keel. 
No two-nerved palea to the terminal flower. 
Stamens two. 
Styles distinct. 
Grain enclosed in the two upper glumes. 
Spikelets crowded on the branches of the panicle; outer glumes 
as long as the male ones_..... j sit we LE. redolens. 
Spikelets all on slender pedicels; outer glumes shorter than the 
male ones sie see OB : :
