484 SAXTIFRAGACEAE. [ Quintinia. 
Norra Istanp: Common in forests from Mangonui to Taranaki and Hawke’s 
Bay. Sea-level to 3500 ft. Tawheowheo. October-November. 
Very variable in the size and shape of the leaves. On high mountain-ranges they 
become shorter, broader, and more obtuse, and the plant is then probably identical 
with Hooker’s Q, elliptica. This is said to have elliptic or elliptic-lanceolate entire and 
obtuse leaves, and was collected ih some locality on the east coast by Colenso, 
2. Q. acutifolia 7. Kirk Students’ F I. (1899) 137.—A small tree 20-40 ft. 
high, with a trunk 1-2 ft. diam. Branchlets, leaves, and racemes viscid 
and clothed with lepidote scales. Leaves much broader and thinner than 
in Q. serrata, 3-Tin. long, 1-2in.. broad, obovate or obovate-oblong or 
elliptic-oblong, rarely oblong- or elliptic-lanceolate, narrowed into a short 
stout petiole, acute or subacute, remotely and often obscurely sinuate- 
serrate. Racemes 2-4in. long, always much shorter than the leaves. 
Flowers much as in Q. serrata, but filaments usually shorter. Capsule 
slightly larger.—Cheesem. Man. N.Z. Fl. (1906) 135. Q. serrata var. b

Norru Isnanp: Little Barrier Island, 7. F. C. ; East Cape, Bishop Walliams / 
Sourn Istanp: West Coast, from Collingwood to Hokitika, W. 7. L. Travers, T. Kirk ! 
R. Helms ! T. F.C, ; 
An ‘exceedingly puzzling plant. It is certainly connected by numerous inter- 
mediates with the typical state of Q. serrata, but its extreme forms appear much too 
distinct to admit of the two species being united. It is abundant on the Little Barrier 
Island, where the leaves attain an extreme length of 8in. by a breadth of 24in. 
Southern specimens have smaller and more elliptic leaves. 
9. IXERBA A. Cunn. 1&%%9. 
A small glabrous tree. Leaves opposite, alternate or whorled, ex- 
stipulate. Flowers white, in terminal panicles. Calyx-tube short, adnate 
to the base of the ovary; lobes 5, imbricate, deciduous. Petals 5, 
inserted beneath a 5-lobed disc, obovate, clawed, imbricate. Stamens 5, 
alternating with the lobes of the disc; filaments filiform. Ovary superior, 
conical, 5-lobed, 5-celled, narrowed into a subulate twisted 5-furrowed 
style; stigma acute; ovules 2 in each cell, collateral. Capsule coriaceous, 
broadly ovoid, 5-celled, loculicidally 5-valved; valves extending through 
the style, ultimately recurved, cohering below, 2-partite above. Seeds 
large, oblong, compressed, shining ; funicle thick; embryo large; albumen 
very scanty. 
A well-marked monotypic genus, confined to New Zealand.

1. I. brexioides A. Cunn. Preewr. (1839) n. 580.—A small branching 
tree 20-50 ft. high, rarely more, with a trunk 1-2 ft. diam. Leaves 3-6 im, 
long, 4-1 in. broad, linear or linear-lanceolate, coriaceous, glabrous, acute 
or subacute, obtusely serrate; teeth tipped by a gland. Flowers large, 
1-14 in. diam.; pedicels jointed, silky. Calyx-lobes broadly ovate, silky. 
Capsule 2in. diam.—Hook Ic. Plant. (1842) tt. 577, 578; Raoul Chore
