Victorian Nat., XXIII (1906), p. 43. 
A shrub of about 9 inches, diffuse or prostrate, with hairy branches. 
Leaves nearly sessile, spreading, lanceolate, with sharply pointed tips, 
fringed with hairs, lighter beneath, with 6 or so fine longitudinal, ‘nearly 
parallel veins, diverging at the margin, 6 to 9 mm long. Flowers 
clustered at the bases of the branches, with small obtuse bracts and 
bracteoles. Sepals about 1 mm long, ovate-lanceolate and obtuse, white 
or pink. Corolla tube much inflated, whitish, transparent. about 5 mm 
long, with an oblique neck bent inwards towards the centre of the 
cluster. The lobes about 1 mm long, pale greenish, the throat with a 
few inconspicuous hairs; hypogynous, with a truncate disc. Ovary

This variety differs from A. serrulata in the broader leaves with 
more numerous veins, in the larger flowers, and in the swollen, oblique 
corolla. 
386. Poa Hackelii F. M. Reader in Victorian Nat, XXIII (1906), p. 89. 
A perennial swamp and water grass, from under a foot to more 
than three feet high. Culms shortly ascending at the base, compressed, 
striate and grooved. Leaves flat, auricled, the broadest about 2 lines 
wide, the longest about 8 inches long, slightly scabrous above, more so 
underneath, narrowed into a pointed, short, and keeled channed, the 
margins being somewhat folded over towards the apex and meeting at 
the summit. Upper leaves usually erect; basal and lower leaves and 
sheaths soon becoming dry, membranous, and brownish. Sheath com- 
pressed, generally rather loose and more or less scabrous. Nerves more 
or less prominent and of unequal thickness. 
Ligule large, oblong with a broader base, upwards to more than two 
lines long, very obtuse and slightly rounded. 
Panicle attaining the length of 1!/, feet, at first contracted, finally 
very loose, in proportion to its size few-flowered. 
Branches capillary, fascicled, usually in threes or fours, more or 
less compressed: and angular, scabrous, erect, irregularly spreading or 
reflexed. Spikelets singly pedicellate, rarely more than five lines long 
with seven or less to nine flowers. 
Empty glumes subequal, glabrous, and the margin broadly mem- 
branous, about two lines long, three-nerved, with a strong keel, which 
is slightly scabrous towards the apex. 
Flowering glume nearly 2!/ lines long, ovate-oblong, obtuse, five- 
netved, at the margin narrowly membranous, broadly so across the apex, 
shortly silky villous along the keel and marginal nerves to about !/, of 
their length, and to about */, on the interstice between them. 
Palea néarly as long as the flowering glume, narrower, with a. 
strong green nerve, otherwise membranous, slightly scabrous along 
the keel. 
Fruit not seen.
