September, 1933. The Queensland Naturalist 81 
tex- 
tile narrower ones nearly three times as long as broad, 
mostly about 3 inches long; petiole or leaf -stalks about i 
inch long; lateral nerves and intermediate veins more or 
less clearly discernible on both faces, main nerves 3-4 
lines apart but often the finer intermediate ones scarcely 
distinguishable from them; intra-marginal vein 4 to 1 line 
removed from the edge, but occasionally very strong and 
far removed (up to 3 lines) from the edge, m which case 
tnere is another right close to the edge itself. Ordinary 
(secondary or adult leaves) coriaceous, straight or falcate, 
lanceolate, apex acute, base acute, often unequal sided, 
sometimes markedly so; petiole twisted, about 4 inch long, 
biade up to 7 inches long and 1^ inches broad in the 
coarser leaved forms, averaging about 5 inches long and 
less than 1 inch broad in the narrower leaved ones; mid- 
rib distinct on both faces, lateral nerves and veinlets more 
or less clearly discernible on both faces, particularly in the 
less coriaceous leaves, lateral nerves 1-2 lines apart, 
oblique, arising from the midrib at an angle 40 to 60 de- 
grees; intramarginal vein in the broader leaves up to 4 
iine removed from the edge, but in the narrower ones 
much closer. Flowers in umbels, the umbels arranged in 
terminal panicles, individual umbels 3-7 flowered, peduncle 
-4 inch long, angular or flattened. Calyx tube narrowly 
turbinate, merging at the base into the somewhat flattened 
or angular pedicel, calyx and pedicel together 4 lines long. 
Operculum conical, 2 lines high. Stamens in several series,, 
the outermost filaments bearing small abortive anthers, 
outer filaments about i inch long, innermost ones only 
about half this length; anthers at first opening by terminal 
pores, but the pores developing with age into rather short, 
wide slits. Seed capsules broadly turbinate, sometimes 
slightly contracted at the orifice, about -J inch in diameter 
on an angular pedicel of 1-2 lines; 3-5 celled, the valves 
flush with the rim or very slightly protruding. 
Distribution. — Eastern Australia from Southern New 
South Wales (according to Maiden within a few miles of 
the Victorian border) to the Wide Bay District, Queens- 
land. Never found any great distance from the coast. 
Comm on Name. — Grey Ironbark is the established 
vernacular for this species in Queensland. 
Botanical Name . — Eucalyptus (see under No. 1) pani- 
culata , paniculate referring to the arrangement of the 
flowers (from the Latin panicula , a tuft). 
Timber. — One of the most extensively used of all Aus- 
tralian hardwoods, especially favoured where great strength 
and durability are required. 
Botanical Reference. — Eucalyptus paniculata Smith in 
Transactions of the Linnean Society of London, 1797.
