4. U. delicatula, Cheesem. n. sp.—Habit of U. nove-zealandie, 
but much smaller, the scape seldom more than 3in. high. Leaves 
1 or 2 or wanting, narrow-linear or narrow linear-spathulate, quite 
entire. Scape 1-3in. high, slender, wiry, erect, 1-3-flowered ; 
bracts very small. Flowers shortly pedicelled, about +in. long, 
white with a faint yellow eye. Calyx-segments almost equal, sub- 
orbicular, concave. Upper lip of corolla the smaller, linear-oblong, 
two-lobed at the tip; lower lip with a horizontally spreading 
lamina which is quite entire, not 3-lobed; palate very obscurely 
thickened or quite plane; spur longer than in U. nove-zealandie, 
minutely 2-horned at the tip. Capsule globose, membranous, about 
tin. diam.

Carse! swamps near Ohaupo (Waikato), 7. F. C. November—January. 
This differs from U. nove-zealandié in the smaller size, in the upper lip of 
the corolla being 2-lobed, and in the longer spur, which is minutely 2-horned 
at the tip. From U. Colensoi it is at once separated by the entire lower lip. 
5. U. Colensoi, Hook. f. Fl. Nov. Zel. i. 206.— Altogether like 
U. nove-zealandie but with the upper lip of the corolla linear- 
oblong, 2-lobed ; lower broadly cuneate, 3-lobed, middle lobe retuse, 
dise with 3 gibbous prominences.’’—Handb. N.Z. Fl. 223. (2) U. 
vulcanica, Col. in Trans. N.Z. Inst. xxvi. (1894) 318.

This does not seem to have been collected since its first discovery more than 
fifty years ago, unless Colenso’s U. vulcanica be the same species. Mr. Colenso 
describes his plant as having a 3-lobed lower lip, but he also states that the upper 
lip is ‘‘subovate, obtuse,’ which is at variance with Hooker’s description. Un- 
fortunately, the type specimens of both species have been lost, so that no com- 
parison can now be made. 
6. U. monanthos, Hook. f. Fl. Tasm. i. 299.—A minute stemless 
herb. Roots or rhizome very slender, bearing several subglobose 
compressed bladders ;+,-;,in. diam. Leaves few, all radical, 4-1in. 
long, narrow linear-spathulate, petiolate, quite entire. Scape 
slender, simple, erect, 3-4 in. high, 1- or rarely 2-flowered. Flowers 
large for the size of the plant, 4in. diam. or more, dark violet-purple 
with a yellow eye. Calyx-segments oblong, obtuse. Upper lip oi 
corolla much the smaller, broadly cuneate, retuse ; lower lip ex- 
panded into a broad semicircular horizontally spreading lamina ; 
palate glandular; spur short, obtuse. Capsule globose, mem- 
branous.—Handb. N.Z. Fl. 222.

Easily recognised by the large dark-purple flowers. For a description of the 
bladders, and for some notes on the fertilisation, see Mr. G. M. Thomson’s 
paper on the fertilisation of New Zealand flowering-plants (Trans. N.Z. Inst. 
xiil. 278).
