1. U. protrusa Hook. f. Fl. Nov. Zel. i (1853) 206.—Stems floating in 
still water, branched, often extending to a length of several feet, slender, 
filiform. Leaves numerous, all submerged, spreading, pinnately multi- 
partite; segments many, filiform; bladders numerous, about 4 in. long, 
obliquely ovoid, shortly pedicelled, attached near the base of the segments. 
Scape stout, erect, 2-4-flowered. Sepals oblong. Corolla yellow; upper 
lip 3-lobed; lower broader, subquadrate, its disc protruded, margins 
recurved. Spur short, obtuse—Handb. N.Z. Fl. (1864) 509; Cheesem.

Mr. Allen’s specimens are in full flower, and are the first found in that condition 
since the original discovery of the species by Mr, Colenso in 1842. 
2. U. Mairii Cheesem. Man. N.Z. Fl. (1906) 560.—Stems floating in 
still water, sparingly branched, 2-6 in. long, stouter than in the preceding 
species. Leaves numerous, all submerged, spreading, about 4 in. long, 
pinnately divided into numerous capillary segments; segments broader 
than in U. proirusa; bladders numerous, about 75 im. long, attached to 
the segments. Flowers not seen.

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 din. across. U. Mavzria was destroyed 
in the Rotomahana locality by the eruption of 1886, but it probably occurs in some 
of the lakes in the Rotorua district. 
a 1 novae-zealandiae Hook. f. Fl. Nov. Zel. i (1853) 206.—Stemless. 
Roots slender, creeping, bearing numerous shortly pedicelled bladders 
about 4in. diam. when fully grown. Leaves 1-3, all radical, often dis- 
appearing at the time of flowering, }-? in. long, rarely more, very narrow- 
linear or linear-spathulate, quite entire, rather fleshy, l-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, +-4in. long, pale-purple with a yellow eye. Upper calyx- 
segment orbicular or nearly so, rounded or slightly retuse at the tip; 
lower rather smaller, concave, 2-lobed. Upper lip of the corolla much
