fully developed and gaping, that I had no difficulty in so doing, 

 and that without breaking-up or even gathering the specimen.* 

 Its form is striking, and its habit peculiar ; all its floral parts 

 being so very open and free, and its lateral sepals wholly de- 

 flexed horizontally ; in these characters I have not seen any- 

 thing like it among all the flowers of the genus, neither in these 

 species of New Zealand, nor in those of Australia and Tasmania. 

 Obs. II. I may also remark that a slenderer plant of the 

 same height grows close to the above, (in the pot,) as if from a 

 twin-tuber, the three leaves of this are near the top of its stem, 

 and are about as long as those of the other, but are sub-linear- 

 spathulate ; it has also a similar scarious bract at the base. It 

 may be the barren or leafing form (young) of this species ; as 

 such obtains among some of the Australian and Tasmanian 

 species — as, for instance, in Pi. obtusa, Br., Hook, fil., "Flora 

 Tasmania*," pi. 115, C. 



2. P. rubella, sp. nov. 



Small, erect, slender, glabrous, 3-4 inches high. Leaves 

 2-3 at base, cordate, 3 lines long, petioles same length ; cauline 

 bracts 4, ovate-lanceolate, the lowest petiolate, the upper 3 ses- 

 sile, half-clasping. Flower solitary, erect, 6-7 lines long ; dorsal 

 sepal arched, convex, striate, very acuminate, 9 lines long ; 

 lateral sepals (lower lip) connate, emarginate, with two long 

 slender green tails, erect and spreading, 10 lines long, rising 

 much above galea ; petals, lanceolate-acuminate, acute, of same 

 length as dorsal sepal ; lip glabrous, dark-red, linear-lanceolate, 

 acuminate, 4 lines long, under 1 line wide, grooved, tip thickened, 

 obtuse ; appendage curved, red. trifid-laciniate and minutely 

 fimbriate or sub-penicillate, not villous ; column, wings red, 

 rounded above, not horned, largely produced and slightly fim- 

 briate below.

Ubs. A species having some affinity with P. trullifolia, 

 Hook. fil. 



3. P. tristis, sp. nov. 



Plant very small, rather dingy-looking, with a greyish-green 

 appearance. Leaves small, 5-7 sub-rosulate, broadly ovate, 

 obtuse or sub-acute, thickish, pale-green, deeply pitted, sub- 

 concave, midrib stout, white and prominent below, margins 

 closely and finely sub-crenulate, about ^ inch long, including 

 petiole ; petiole very broad and stout, 2-3 lines long, white, 

 with three green veins. Scape stoutish, 2-2^ inches high, with 



* I have, however, since writing the above, received flowers of several 

 plants from Mr. Balfour, which fully agree with my description. (November, 

 1885.)
