(Page 19.) Pterostylis pedunculata, Br., and P . nana, Br.
Ai'cLer considers tliat the figures A and B of Plate CXRÁ are reversed ; A being P. nana, and B. pedunculata.
Neither are good, but A certainly belongs to P. pedunculata, though the leaves should be more oblong and
petioled. B is perhaps the Australiau P. concinna, Br., a larger plant than P . nana, but otherwise very near it.
Pterostylis ohtusa, Br., ofteu bears withered radical leaves on the flowering scape (Archer).

(Page 24.) Microtis rara, Br., is, as Dr. Lindley informs me, found in New Zealand (M. ponifoUa,
Spr.), Java, New Caledonia, aud the Island of Bouin.—On re-examining the Tasmanian aud Australian
species of Microtis with the descriptions and drawings of this work, I find them to be inextricably confused,
and do not see how to discriminate them.

H a b . Base of Mount Wellington (Oct., Nov., 1839-40), Gtmn.
This very distinct little plant was sent to me by Mr. Gunn in a letter, and, Hke the Caleana minor, arrived
only as this sheet was passing through the press. It is of the same size as, and a good deal like, A. exsertus, but
at once distiuguished by its fewer flowers, green colom-, bluut sepals, the lateral of whieh are recurved, minute petals,
and veiy broad trapezoid labellum. The soHtaiy leaf has undulated, almost creuate or sinuate margins.

I omitted quoting Lindley, Gen. et Sp. Orch. p. 422.—Su-eet-scented. Archer has Lindlej’s variety f t in
which the glauds are always in four rows ouly.
Caladenia pallida, Lindl.
Archei- is doubtful as to this being distinct from C. Patersoni, and, ivith justice, quotes the figm-es of this
work in corroboration. Mueller, on the other hand, considers all the species of the second section to be forms of one !
(Page 29.) Caladenia harhata, Lindl.
Archer remaiks that the old and young tubers are enclosed in a common tunic, as in Glossodia major.
(Page 30.) Caladenia a/a/a, Br.
Archer remarks that Brown’s plant is described as having the glands biscriate, and that it has a musky odoiu-.
(Page 32.) punctatum, Br. (Tab. CXXVII.)
By au unfortunate oversight the colouring of this Plate is very incomplete and inaccurate. It is well represented
in the works quoted after the diagnosis,—Smith’s ‘ Exotic Botany ’ and Lindley’s ‘ Botanical Register,’—and
(as there represented) the scape should be washed over with a pale broivn, leaving hai'dly a trace of green, and the
flowers should be spotted.

I am indebted to Dr. Mueller for specimens of this curious and very interesting plant, but they are in too
imperfect a state for a satisfactoiy description ; it is a small species, with alternate subulate leaves 1 -3 inches long,
and tufted fibrous xocia.— Floicers small, yellowish, soUtary, opposite the leaves.

Mr. Gumi has sent me a httle fragment of a second species of this genus, gathered on the east coast, also by
Dr, Milligan, which Dr. Lindley informs me is quite new, aud allied to the B. Milligani.

A very distinct species, though siiuflar at fii'st sight to P. glauca. I am indebted to Mr. Archer for drawing
my attention to it in his herbai-ium : it does not occur iu Giiun’s (whose specimens I have again examined in the
vain endeavour to find more thau one species amongst them). P. longiscapa is easily recognized by the scape
longer than the leaves, and thickened below the spatha ; by the spatha uot being striate, and by the pilose tube of
the corolla. The stigma appears to be erect. The quotation of the Bot. Mag. t. 2677, under P. glauca, should
be cancelled.

This is certainly the Z. Preissii, which I have doubtfully quoted, and differs from the ordinary forms of
Z. palustris in the longer, slender style, even back of the carpel, and apparently six-celled anthers. Tiic carpels and
style, however, vary extremely in European specimens of Z. palustris, aud I suspect that most of tiie so-called
species of tiiis genus will ultimately be reduced to that plant.
