Nort Istanp: Auckland—Lake Tongonge, near Ahipara, R. H. Matthews! 
Lake Waihi, Waikato, Kirk! T. F.C.; Bay of Plenty, Colenso. 
I have taken the description of the inflorescence, &c., from the Handbook, 
the plant occurring in Lakes Waihi and Tongonge not being known in a 
flowering state. It may not be identical with Hooker’s U. protrusa, the 
type specimens of which have been unfortunately lost. 
2. U. Mairii, Cheesem. n. sp.—Stems floating in still water, 
sparingly branched, 2-6in. long, stouter than in the preceding 
species. Leaves numerous, all submerged, spreading, about in. 
long, pinnately divided into numerous capillary segments; seg- 
ments broader than in U. protrusa ; bladders numerous, about +4, in. 
long, attached to the segments. Flowers not seen. 
NortH Isptanp: Auckland—Lake Rotomahana, Kirk and Captaim G. 
Mair! (1872). 
This is certainly distinct from the Lake Waihi and Lake Tongonge plant, 
which has stems several feet in length, and the branches of which, with the 
spreading leaves, are from 14-3 in. across. In U. Mairii the stems are much 
shorter and stouter, and the branches with the leaves on are only about 4 in. 
across. Which of the two plants corresponds to Hooker’s U. protrusa can only 
be determined when flowering specimens are obtained. U. Mairii was de- 
stroyed in the Rotomahana locality by the eruption of 1886, but it probably 
occurs in some of the lakes in the Rotorua district. 
3. U. novee-zealandize, Hook. f. Fl. Nov. Zel. i. 206.—Stemless. 
Roots slender, creeping, bearing numerous shortly pedicelled 
bladders about 4in. diam. when fully grown. Leaves 1-38, all 
radical, often disappearing at the time of flowering, +-2in. long, 
rarely more, very narrow-linear or linear-spathulate, quite entire, 
rather fleshy, 1l-nerved. Scape or peduncle very slender, variable 
in length, 3-9 in. high or more, simple, erect, 1-4-flowered; bracts 
small, opposite or in threes. Flowers shortly pedicelled, }+in. 
long, pale-purple with a yellow eye. Upper calyx-segment orbi- 
cular or nearly so, rounded or slightly retuse at the tip; lower 
rather smaller, concave, 2-lobed. Upper lip of the corolla much 
the smaller, narrow cuneate-oblong, constricted below the middle, 
truncate or nearly so at the tip; Jower lip with a broad horizontal 
almost semicircular lamina about 4 in. diam., margin entire; palate 
with three raised ridges, each with a central groove; spur short, 
broad, obtuse. Capsule membranous, globose, 4in. diam. —

Probably not uncommon in peaty swamps throughout the North Island, 
but easily overlooked.
