but not so prominently as the undersides of the leaves. Panicle loosely 
pyramidal three to six inches long, with short horizontal, rather rigid 
branches, the lower ones an inch and a half long, the upper ones shorter. 
Spikelets clustered, pedicellate, very flat, of a pale leaden colour when 
joung, finally assuming a light straw colour, three to seven lines long 
and iwo lines broad, with from ten to thirty or more flowers, the rhachis 
at length articulate. The outer empty glumes rather unequal and 
somewhat shorter than the flowering ones, keeled, with faint lateral 
nerves. Flowering glumes distichous, one line long, obtuse, the lateral 
nerve on each side near the margin and very prominent. Palea shorter 
than the flowering glume, incurved, thin, the keels sdarsely ciliate. 
Stamens usually three, with very small anthers. Grain free, brown when 
ripe, and very broadly ovoid.

Eragrostis. costata belongs to the Megastachya section of the genus, 
and its affinities are E.«brownii Nees (a species common to many parts 
of Australia, and E concinna Steud. (a North and Central Australian 
grass) It differs principally from the polymorphous species E. brownii 
Nees, by its distinetly pedicellate spikelets, its obtuse flowering glumes, 
and its very prominent lateral nerves being nearly marginal; and from 
E. concinna Steud., principally by its leaves, the disposition of its in- 
florescence and its flowering glumes and palea.

A tall tree, attaining sometimes a height of 100 feet, with a dark- 
coloured ,stringy bark“ which runs right out to the branchlets. Abnormal 
leaves opposite, sessile, cordate, ovate, acuminate, thin, pale-coloured on 
the underside where the venation is more pronounced, upper surface 
Shining, over 3 inehes broad, and sometimes 6 inches long. Normal 
leaves lanceolate-faleate, varying in length up to 8 or 9 inches, and in 
breadth from under 1 inch up to nearly 3 inches, and often very oblique 
at the base, the larger leaves especially so, coriaceous, pale-coloured on 
both sides. Venation well pronounced in the abnormal, but not quite so 
distinct in the normal leaves; the intramarginal vein is well removed 
from the edge, and the lateral ones are distinct, oblique and spreading. 
Inflorescence occurs mostly in terminal panicles, but occasionally in 
axillary peduncles. Calyx turbinate, gradually tapering into the flattened 
pedicel. Operculum hemispherical, shortly acuminate. Fruits hemis- 
pherieal, about 3 lines in diameter, rim thin, valves sunken.
