in texture, channelled, li^'litly covered witli minute simple 
hairs, about 2.7 cm lon^ and 4 mm Avide. l^acemes few- 
floAvered, about 4 cm lon^. reddisli, minutely hairy, A'ery 
slender at the base and tiiickeniu*^ towards the top; bracts 
minute, deltoid, persistent. Pedicel and ovary about 7 mm 
lon^, crimson flushed. PioAvers about 7 mm lon^. Sepals 
and petals Avhitish -with dark crimson margins and a 
ligliter crimson median line. J)orsal sepal linear, sub- 
acute, 4 mm Jong. Latc'ral sepals adnate to the base of 
the column, similar to the dorsal but bent forAvards and 
upAvards to embrace the free lamina of the labellum. l^etals 
similar to the dorsal sepal, widely expanding and some- 
Avhat recurved. Labellum sessile at the base of the column, 
lamina 4 mm long and 2 mm Avide, greenish yelloAv, thick 
in texture, recurved, ehanelled inside from the base almost 
to the base of the mid-lobe; lateral lobes erect, broad, 
acute; mid-lobe represent(‘d by an arc with upturned 
margins; plate minutely glandular; sac 2 imn long, 
slender, chaniu'lled outside, holloAV and Avithout ornaimm- 
tation. Column 2 mm long, slendei*, curved, Avhitish, Avith 
a. dark crimson margin at th(‘ top, Avinged, the Avings in 
th(‘ type flowt'r (mibracing the stigma; anther large, 
beaked, orange and crimson; rostellum very long, pro- 
jecting doAVjiAvards parallel with and in front of the 
stigma ; stigma long and slender, in the type floAvor 
partially covert'd by the column Avings; pollen masses two, 
sulcate, orange; 'lAedit-el ligulate. 
The discovery of this plant by i\lr. llockings, of 
Wunbuj-ra, is of more than oi'dinary interest bt'caust^ the 
area is quite closely settled and has been well knoAvn 
botanically for vt'ry many years. Doulitless it has bet'ii 
passed by because of its close resemblance to the juvcjiile 
stages of some of the better knoAvn nu'iubt'rs of the 
HarcanUi'niae that inhabit the area. Noav that it is knoAvn 
it should be reasonably easy to identify hi the field aa'Iicu 
not in floAver because of its small size and the stiffness and 
thickness of its fcAv leaA’es. Jn floAver, of course, the dis- 
tinctiAT rich crimson striping of the segments, tlie brilliant 
colour of the top of the column, and the peculiar tAvisting 
of the lateral sepals, make identification much more 
simple. 
KEY TO PLATE 
a. Fiower from side; b, Column from side; c. Lamina of label- 
lum from above; d. Pollinia; e. Flower from front; f. Lamina of 
labellum from side; g. Plant, life size; a. to f. Variously enlarged; 
g. Is little more than diagrammatic as it was sketched from 
memory, the original plate having been unfortunately mislaid 
and the plant was not available for the preparation of this one.
