A NEW ORCHID FOR SOUTH QUEENSLAND 
Acianthus LedwardU, sp. nov. 
By the Rev. H. M. R-. Rupp, Raymond Terrace, N.S.W. 
Planta A. fornicato similis, circiter 5 cm. alta, folio 
supra pallido. Flores 2-6. Sepalum dorsale cucullatissi- 
mum, mucronatum: sepala lateralia linearia, directa, in- 
signiter ad apices trifida: petala late lanceolata, acuta: 
labellum ovatum, infra convexum, cum marginibus incur- 
vatis serrulatisque. Discus posteriore levis, anteriore 
papillosus. Columna flexa cum apparato reproductivo 
sicut in A. fornicato. 
Plant resembling A. fornicatus R. Br., about 5 cm. 
high, leaf pale green above. Flowers 2-6, somewhat de- 
pressed. Dorsal sepal deeply hooded, mucronate at the 
apex, with a short depressed point. Lateral sepals linear, 
parallel (not divergent as in A. fornicatus ), near the apex 
shortly and prominently trifid, the outer divisions shorter 
than the middle one. Petals broadly lanceolate, short. 
Labellum ovate, convex below, with incurved serrulate 
margins. Disc smooth towards the base, papillose towards 
the blunt apex, lacking the papillose longtiudinal ridges 
of A. fornicatus. Column bent, reproductive apparatus 
as in A. fornicatus , but stigma less prominent. 
Burleigh Heads, South Queensland, June, 1934, and 
June, 1938: Dr. C. P. Ledward. 
Some doubt has been felt, both by the discoverer and 
myself, whether this interesting little orchid might not be 
included in A. fornicatus , to which it is very obviously 
related. The gynostemium is identical in almost every 
particular. But the labellum is so strikingly different, 
and other features of the flower give it such a distinctive 
appearance, that it could only be placed in A. fornicatus 
by extending the description of the latter to cover far 
greater variability than seems desirable. A. fornicatus 
is an exceedingly common terrestrial from Southern 
Queensland to Southern New South Wales, and in the 
latter State is found as far west as Molong. Among the 
thousands of plants I have seen over many years, there 
was never one with a labellum like that of Dr. Ledward ’s
