ceous. Spike 2-10-fiowered. Flowers excessively variable in size; sepals 
blue or purple, in. diam. ; petals paler ; both ovate-lanceolate, acute. 
Lip obovate. Column with rounded tip, the appendages excessively short, 
villous anteriorly. — T. stenopetala, Hook. f. FI. Antarct. i. 69; Serapias re- 
gular is, Forst. Prodr. 
Abundant throughout the Northern aud Middle islands, Banks and Solander, etc. 
Xaord Auckland’s Island, J. B. H., Bolton. A most variable plant in stature and ro- 
bustness, the length and breadth ot' the bracts and leaves, and the number and size of the 
flowers. Apparently identical with the Tasmanian aud Australian T. nuda, Br. 
2. T. pulcbella. Hook. f. FI. N. Z. i. 214. A very handsome species, 
differing from T. longifolia in the usually broader sepals and petals, and the 
longer, erect, toothed appendages of the column. Flowers f~l in. diam., 
fine blue-purple. 
Northern Island, Colenso. Middle Island: Moutere hills, Munro ; Otago, Lyall. 
Probably a state of T. Forsteri. 
3. T. uniflora. Hook. f. FI. N~. Z. i. 70. Short, stout, 6-8 in. high. 
Leaf narrow-linear, fleshy, obtuse, channelled, curved, shorter than the scape. 
Flowers 1-3, pale blue, | in. diam. Sepals and petals linear-oblong, 
acute or acuminate. Lip obovate-cuneate. Appendages of column erect, 
linear, 2 -fid at the tip. 
Middle Island : Milford Sound, Lyall. Eiord Auckland’s group, Le Guillon, etc. 
4. T. Colensoi, Hook. f. — T. paucijiora, FI. N. Z. i. 244, not Br. 
Very slender, 8-12 in. high. Leaf very narrow linear, flexuous. Flowers 
1-3, yellowish, on slender pedicels, \ in. broad. Sepals and petals very 
narrow, linear-oblong, acute. Column very short; appendages very long, 
subulate, erect, plumose at the tip. Anther with a long point. 
Northern Island, Colenso. This differs from all the other species, and from the Aus- 
tralian T. paucijiora, to which I had united it, in the very narrow sepals and petals, very 
short column, and very long erect appendages. 
5. T. imberbis, Hook. f. FI. N. Z. i. 244. Small, slender, 4-10 in. 
high. Leaf very narrow linear. Flowers 1 or 2, yellowish, about £ in. diam. 
Sepals and petals very broad, orbicular-ovate, obtuse. Column rather short ; 
appendages curving upwards and forwards, with crenate fimbriate or slightly 
villous tips. Anther with a long broad point. 
Northern Island, Colenso. Much better specimens of this aud the preceding arc 
wanted to establish their distinctness ; this is very like the Tasmanian T. carnea, but the 
flowers are said to be yellow. 
16. SPIRAiNTHES, Richard. 
Terrestrial, erect, glabrous or puberulous herbs. Root of unbranched 
fibres or much divided tubers. Stem simple, leafy. Flowers spiked or ra- 
cemed. — Perianth nearly closed. Lateral sepals usually saccate at the base; 
upper ascending. Petals similar but narrower. Lip inferior, shortly clawed, 
quite entire, concave, embracing the column at its base. Column short, 
without lateral appendages. Anther at the back of the column, persistent,
