Of this species I possess only the old scapes, which are about six inches long, each bearing a solitary cap-
sule, with the withered perianth. The leaves I have never seen, but there are traces of sheaths or leaves on
the scape, and of a larger one, probably a bractea, below the flower. The capsule is turgid, elliptical-obovate,
erect, about half an inch long and quite glabrous. The leaflets of the perianth are rather shorter than the
capsule and strongly nerved, as is the labellum, which is rounded at the lower extremity, with a short apiculus.
The anther is inserted a little below the apex of the column.
I am very uncertain as to the genus of this plant ; it diflrers from any with which I am acquainted ; yet I
am unwilling, in the absence of better specimens, to constitute a new one of it. In the petaloid, very distinct
lateral lobes of the column, which is 3-cleft nearly to the base, it shows some analogy to Diuris, and m the terminal
anther to the group wiiich includes Caladenia and many other New HoUaud Orchidea:, The regular and
nearly equal leaflets of the perianth, to which the labellum is very similar in form and structure, induce me to
retain it among Thelymiirm. I t is further undoubtedly nearly allied to a plant Included by Mr. Gunn under the
genus Macdonaldia (vid. Lindi. Swan River Botany, p. 30. no. 217, and Gen. and Sp. Orchid, p. 385), which
contains two Tasmanian species, one M. Smithiana, Lindi. (I. c. t. 9. B.), in which the column is undivided or
obliquely trifid or three-lobed ; the rounded anther is situated below the apex of the column, on its inner face,
and is villous ; in the colour and appearance also of the plant, and in the shape of the leaflets of the perianth,
it differs from Thelymitra. The other species, M. cyanea. Lindi., very much resembles the more ordinary forms
of Thelymitra in size, habit, colour, and in the shape of the perianth ; in the more terminal acute anther and in
the lateral lobes of the column being produced upwards beyond the anther and bifid at the apex, it agrees with
the T. ? !

This apparently belongs to the genus Caladenia, but It is in a very young state, and tbe glands on the
labellum are probably undeveloped. The roots are small, oblong tubers, connected by a terete cauliculus. Leaves
4 -2 inches long. The only flowers I possess are ju st emerging from a large cucullate bractea; they are of a
pale flesh-colour mixed with yellow.

What I take to be the leaves of this plant (for though growing along with the scapes they were not
attached to them) are solitary or rarely two together, arising from a short cauliculus terminating in an
elongated tuber and throwing out stout horizontal fibres from its lower extremity. The withered scapes, which
bear solitary capsules, are 2 -3 inches long ; the capsules half an inch long, oblong-turbinate, obscurely glandular,
and crowned with the reflexed leaflets of the perianth. In one specimen the labellum was furnished with only
four glands in two lines ; in another they extended to the middle with four or six in each series.

I have seen neither flower nor fruit of this plant, and only a withered capsule of what I bebeve to be Mr.
Cunningham’s A. rivularis. gathered in New Zealand by Mr. Colenso. The leaves of the former vary very much in
size and shape according to their age ; the younger ones are cordate or ovate and cordate at the base, acute ; as
they grow older they become orbicular, deeply lobed at the petiole, of the same size and texture and similarly
nerved as in the genus Acianthus.
Dubii generis.
The following species I am unable to refer to any genus, the flowers being too imperfectly developed for
a satisfactory determination.

Tubers about 3 bnes long, similar to those of Orchis latifolia. but much smaber ; from these the leaf springs
at once its petiole surrounded by a tubular cylindrical sheath. The leaf is 6-8 inches long, 1-2 lines wide,
acute or blunt at the apex, green, and of a singularly thick and fleshy texture when recent, coriaceous when dry-
and quite black. The youug scape is covered with what appear sheathing cucullate bracts ; they arise one from
tbe base of each of the flowers ; the latter are very small.

The leaves here are 2-3 inches long, very concave ; the periole inclosed in a long scarious sheath which
is split above ; the flower is small and inclosed in two sheatliing bracts. This plant has some points in common
with Chiloglottis, Br., but the leaves are not like those of that genus.
