204 NEW AUSTRALIAN ORCHIDS. 
lines long. Flowers in dense racemes of about twenty to thirty, 
green tinged with olive; sepals and petals about six lines, oblong, 
hardly ac dente: Labellum five lines, three-lobed ; lateral lobes acute, 
about one third of the central lobe, which is obtus se and thick. 
the centre of the disk is a depression, er nae pubescent at the 
sides, and made cordate by a globular gland on the upper side. 
Column hardly i, Sepe as club-shaped or almost terete, 
not globular as in C. su 
Chiloglottis liskira: sp. n.—Leaves two, sessile, oblong- 
lanceolate, acute, about ten lines long and four broad. One- 
owered. Scape about three inches. One large ees acute 
bract below the ovary. Dorsal sepal spathulate, acuminate, 
seven lines long, light red-brown tinged with green. Lateral sopalé 
linear, about seven lines, acute, yellowish. lLabellum about five 
lines, obovate, acute, on a broad claw. One large reflexed callus 
near the base and about nine or ten other large flat calli along the 
centre of the disk, surrounded by numerous small clavate slender 
calli; the large e reflexed callus greenish, the others dark red-brown. 
The labellum itself li ght red-brown. Petals of the same form and 
colour as the labellum, except that the labellum is alone articulate 
and the calli on the petals are hardly so fully developed as on the 
labellum, and the labellum is slightly broader. Column shorter 
than the petals, not much curved and but slightly winged aldlig its 
whole length, the wing extending behind the anther into a deeply 
four-toothed crest; anther with a short point. This is an interesting 
species from the fact that the petals being formed with the pecu- 
liarities of a labellum prove the correctness of the theory that the 
labellum is a transformed petal. C. trilabra was obtained on 
Mount York, in the Blue Mountains, oe S.W., and appears to be a 
very aes species. It flowers in Mar 
Cirrhopetalum clavigerum, sp. n Ne SOkeeping, rhizomes in 
est of about three or four lines, covered with long hairs, especially 
und the pseudobulbs, producing roots below the pseudobulbs and 
‘itll ense patches. doepreey conical, from about six lines 
to one inch six lines long, and about five lines to one inch broad, 
deeply ribbed and furrowed. Leaves thick, oblong, pedicellate, 
from three to six inches long, about one inch four lines broad; 
scape from six to eight inches, slender. Bracts lanceolate, leafy. 
Flowers six or seven, in a horizontal half-circle, on pedicels of ten 
a ll acute bracts at their juncti Do P 
hooded, acute, dull yellow, spotted in parts with purple, about four 
lines long and four broad, terminated in a clava fou 
of their length nearly to the ends, about one inch and a half long 
and three lines broad, acute, yellowish. Petals Saceactaie, ciliate, 
purplish. Labellum thick, lmgulate, much curved, articulate on 
the basal projection of the column Wings of the column recurved 
at the anther, acute. The Cirrhopetalin which —. nearest 
this species, as far as I am aware, is C. Thouarsii Lindle 
. clavigerum was obtained at cate York, Northern Aautentin, and 
flowers in January.
