base, bark rough and corky, slightly furrowed. Leaves 2 to 3 lines in 
length, ovate-lanceolate, stalked tuberculate, semi-terete, flat on top, 
scattered and numerous. Flowers small whitish, numerous in lateral 
Spikes; axis grows through the inflorescence before flowering is over. 
Calyx tube campanulate, lobes 5 triangular nearly as long as the tube. 
Corolla white, petals 5 deflexed, clawed, very thin and delicate. Stamens 
in 5 bundles, opposite petals, 7 to 9 in each bundle. Ovary hairy on 
top, single style and stigma, 3-celled, ovules erect, placenta bifid. — Re- 
marks. This plant differs from Melaleuca pustulata in that its bark is 
not smooth and papery. The flowers of Melaleuca pustulata are in small 
terminal leafy heads, and the rhachis as a rule does not grow out until 
flowering is over. The flowers differ in the two plants in external ap- 
pearance, the calyx lobes of M. pustulata are longer than broad, and 
more pointed. The petals also differ, the petal of M. pustulata being 
longer, more ovate, and claw is shorter. The plant is of no value as 
timber, owing to its small height. Its nonrecognition as a distinct spe- 
cies has been due to its being confused with M. pustulata. Hitherto it 
is only known from Victorian localities. Attention to the possibility of 
this plant proving to be a new species was first drawn by Mr. St. Eloy 
D'Alton. Hence its popular name might be D'Alton's Melaleuca, — Neu-
