(Page 19.) Pterostylis pedunculata, Br., and P. nana, Br. 
Archer considers that the figures 4 and B of Plate CXIV. are reversed; 4 being P. nana, and B. pedunculata. 
Neither are good, but 4 certainly belongs to P. pedunculata, though the leaves should be more oblong and 
petioled. B is perhaps the Australian P. concinna, Br., a larger plant than P. nana, but otherwise very near it. 
Pterostylis obtusa, Br., often bears withered radical leaves on the flowering scape (Archer).

(Page 23.) Chiloglottis Gunnii, Lindl., has been found in Victoria by Mueller. 
(Page 24.) Microtis rara, Br., is, as Dr. Lindley informs me, found in New Zealand (M. porrifolia, 
Spr.), Java, New Caledonia, and the Island of Bonin.—On re-examining the Tasmanian and Australian 
species of Microtis with the descriptions and drawings of this work, I find them to be inextricably con- 
fused, and do not see how to discriminate them.

Has. Base of Mount Wellington (Oct., Nov., 1839—40), Gunn. 
This very distinct little plant was sent to me by Mr. Gunn in a letter, and, like 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, 4. exsertus, but 
at once distinguished by its fewer flowers, green colour, blunt sepals, the lateral of which are recurved, minute petals, 
and very broad trapezoid labellum. The solitary leaf has undulated, almost crenate or sinuate margins. 
(Page 28.) Caladenia Patersoni, Br. 
I omitted quoting Lindley, Gen. et Sp. Orch. p. 422.—Sweet-scented. Archer has Lindley’s variety £, in 
which the glands are always in four rows only. 
Caladenia pallida, Lindl. 
Archer is doubtful as to this being distinct from C. Patersoni, and, with justice, quotes the figures 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 ¿arbata, Lindl. 
Archer remarks that the old and young tubers are enclosed in a common tunic, as in Glossodia major. 
(Page 30.) Caladenia alata, Br. 
Archer remarks that Brown's plant is described as having the glands biseriate, and that it has a musky odour.

` By an unfortunate oversight the colouring of this Plate is very incomplete and inaccurate. It is well repre- 
sented 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 brown, leaving hardly a trace of green, and the 
flowers should be spotted. 
(Page 33.) Gunnia australis, Lindl., has been found at Cape Otway, Victoria, by Mueller, who 
reduces the genus to Sarcochilus (S. Barkleyanus, Fragment. Phyt.).
