1. O. macrophylla, Hook. Ic. PI. t. 545, 546 ; — FI. N. Z. i. 197. 
Erect, more or less pubescent or tomentose. Bhizome short, decumbent at 
the very base. Leaves all radical, long-petioled, 1-6 in. long, oblong or 
ovate-cordate, obtuse, crenate. Scape 2—30 in. high. Bracts on the scape, 
lower pair opposite, upper whorled, all oblong-obovate or linear, very variable 
in form and size, crenate. Flowers umbelled, in superimposed whorls ; pedi- 
cels 1-2 in. long, very slender. Calyx 5-partite; lobes glandular hairy or 
glabrate, linear or lanceolate, i in. long. Corolla ^ in. long. Capsules 
membranous, f in. long, broadly oblong, turgid. 
Northern Island : Mount Egmont, Rnahine range, etc., Dieffenlach, Colenso, etc. 
Middle Island : common in damp mountainous localities. Upper Wairau, alt. 2500-5000 
ft., Sinclair, Travers. 
2. O. macrocarpa, Hook. f. FI. N. Z. i. 198. Erect, nearly glabrous. 
Rhizome prostrate, as thick as the little finger. Leaves all radical, with long 
stout petioles, 4-6 in. long ; blade 1-2 in. long, orbicular broadly oblong 
or ovate-oblong, round at the tip, crenate, coriaceous, glabrous, except along 
the edges of the petiole, veins strongly reticulate. Scape very stout, 8-1 8 
in. high ; lower bracts in pairs, connate, oblong, crenate, upper whorled, all 
coriaceous. Flowers umbelled in several whorls. Pedicels stout, 1-3 in. 
long. Calyx 5-partite ; lobes glabrous, \ in. long, linear-oblong, obtuse, very 
coriaceous. Corolla not seen. Capsule narrow-oblong, \ in. long. 
Middle Island : Chalky Bay, Lyall. Well distinguished from O. macrophylla by its * 
glabrous condition, stout habit, very coriaceous leaves, very large sepals and elongate 
capsule. 
3. O. Colensoi, Hook. /., n. sp. — A small, erect, glandular-pubescent 
species, 2-6 in. high. Bhizome slender, creeping. Leaves ^ in. long or 
less, petiole as long, oblong, obtuse, crenate, pubescent on both surfaces or 
glabrate. Scape 1-4-flowered, slender ; bracts all in pairs, oblong, crenate. 
Flowers solitary or in pairs ; pedicels slender, -|— | in. long. Calyx 5-partite ; 
lobes ] f in. long, narrow-linear, glandular-pubescent. Corolla white, nearly 
f in. diarn. Capsule shorter than the sepals, nearly orbicular. 
Northern Island: top of the Ruahine range and Lake Taupo, Colenso. Middle 
Island: Wairau mountains, alt. 3-3500 ft., Travers.

4. O. sessilifolia, Hook, f., n. sp. Erect, hirsute, and glandular; rhi- 
zome creeping, as thick as a crow-quill. Leaves all radical, f-lx in. long, 
broadly ovate, abruptly narrowed into broad short petioles, crenate-serrate, 
upper surface villous with glandular hairs, lower less so or glabrate. Scape 
stout, 3-4 in. high ; bracts all opposite, oblong or obovate, crenate. Flowers 
in pairs; pedicels rather stout, 1 in. long. Calyx 5-partite; lobes broad, 
linear, obtuse, glandular. Corolla large, nearly 1 in. diam. ; lobes long, 
rounded, white. Capsule not seen. 
Middle Island : Mount Brewster, alt. 5-6000 ft., Eaast. Apparently a very distinct 
plant ; I have only one good specimen.
