at the tips. Leaves alternate, ovate-cordate orbicular-cordate or almost 
reniform, }-2in. diam., obtuse or subacute, obtusely crenate ; petioles 
slender. Stipules broad, deeply laciniate ; teeth filiform, often olandular- 
tipped. Peduncles slender, 2-4in. long; bracts about the middle, linear, 
toothed or lacerate. Flowers }in. diam. Sepals linear-lanceolate. Petals 
spathulate ; spur short—Handb. N.Z. Fl. (1864) 16; T. Kork Students’

Var. hydrocotyloides,7’. Kirk Studer’ Fl. (1899) 41.—Much smaller, sparingly 
pilose. Leaves §—4 in. m. Peduncles short.—V. hydrocotyloides J. Bb. Armstr. 
in Trans. N.Z. Inst. xiv (1882) 360. 
NorrH anp Sourn Isiranps, STEwaRT Istanp: River-valleys and moist places 
southwards from the Hokianga Plateau. Var. hydrocotyloides: Otago, Petrie! Stewart 
Island, Stack / Petrie! T. Kirk! Altitudinal range from sea-level to 4500 ft. No- 
vember—February. 
The long creeping stems, small leaves, and fimbriate bracts and stipules distinguish 
this from the two following. It produces numerous reduced or cleistogamic flowers late 
in summer and autumn. 
2. V. Lyallii Hook. f. Handb. N.Z. Fl. (1864) 16—Perfectly glabrous. 
Stems slender, shorter than in V. filicaulis, ascending at the tips. Leaves 
1-lin. diam., broadly ovate or rounded, deeply cordate at the base, 
obtuse or subacute, obscurely crenate or nearly entire ; petioles variable in 
length, 2-6in. Stipules linear, entire. Peduncles very slender, variable 
in length, 3-7in. Bracts usually above the middle, linear, entire. Flowers 
din. diam., white streaked with lilac and yellow—T. Kirk Students’ £1. 
(1899) 41; Cheesem. Man. N.Z. Fl. (1906) 45. V. Cunninghamii var, gracilis 
Hook. f. Fl. Nov. Zel. i (1853) 16. Erpetion spathulatum A. Cunn, Precur. 
(1839) n. 622 (not of G. Don). | 
Norru anp Souru Istranps: Not uncommon from Kaitaia and Hokianga south- 
wards; ascending to 4000ft. on the Mount Arthur Plateau, Nelson. October— 
January. 
Usually a larger plant than the preceding, with the stem not so decidedly creeping, 
larger leaves and longer petioles, and with the stipules and bracts entire, not lacerate. 
The cordate leaves separate it from V. Cunninghamii. 
3. V. Cunninghamii Hook. f. Fl. Nov. Zel. i (1853) 16.— Glabrous 
except the petioles, which are occasionally pubescent. Rootstock often 
somewhat woody, creeping below, often branched above. Leaves tufted 
at the top of the rootstock, or on short branches springing from it, 4-1 in. 
diam., triangular-ovate or ovate-oblong, truncate at the base or narrowed 
into the peticle, obtuse or subacute, obscurely crenate; petioles short or 
long. Stipules adnate at the base to the petiole, usually entire, acute. 
Peduncles slender, exceeding the leaves; bracts linear, acute. Hlowers 
3-3"1n. diam., white, usually streaked with lilac and yellow. Sepals linear- 
oblong. Lateral petals bearded —Handb. N.Z. Fl. (1864) 16; T. Kirk
