pilose; blade 4-1in. long, ovate-cordate to nearly orbicular, sharply and 
coarsely serrate-dentate, sparsely pilose above and along the veins beneath, 
margins more or less pilose; veins palmate. Flowers unisexual. Male 
flowers on axillary densely pilose peduncles 1-24 in. long, sometimes with a 
few females at the base, very shortly stalked, bracteate; sepals 2, linear- 
triangular; petals 2, narrow-spathulate; stamens 2, anthers broadly 
oblong. Female flowers densely clustered on a_ short peduncle at 
first sunk in the axils of the leaves but which elongates as the fruit 
ripens; sepals 2, narrow-linear; petals wanting. Fruit linear obconic 
or pyriform, ;4,in. long, reddish.— 7. Kirk Students’ Fl. (1899) 154;

Under the name of G. densiflora I have for the present included not only the original 
plant of Hooker, but another collected by Mr. Laing and myself at Lake Tennyson, 
which is considerably larger, but does not seem to differ in any other character of 
importance. Both are very closely allied to the Tasmanian G. cordifolia, and I should 
have referred them to that species but for the fact that the fruit of G. cordifolia is 
described by Hooker in the “ Flora Tasmaniae ”’ as “ aggregated into a head as large 
as a raspberry, bright-red, trigonous,’’ a description which does not at all suit the New 
Zealand plant.

6. G. dentata 7. Kirk in Trans. N.Z. Inst. xxvii (1895) 346.—Forming 
extensive patches in watery subalpine localities. Rhizome stout, much 
branched, clothed with the bases of the old leaves. Leaves numerous, 
densely tufted, 1-3 in. long; petioles long, broad and flat, usually clothed 
with strigose hairs, sometimes almost shaggy; blade 4-1 in. long, ovate 
or elliptic-oblong or elliptic-lanceolate, acute, rounded or cuneate at the 
base, often narrowed into the petiole, coarsely dentate, both surfaces with 
scattered white hairs or almost glabrous. Spikes unisexual. Male spikes 
slender, about equalling the leaves; flowers sessile or nearly so, each with a 
pair of deciduous hood-shaped bracts. Sepals 2, minute, linear. Anthers 
broadly oblong. Female spikes very short, hidden at the’base of the leaves; 
flowers densely crowded. Calyx-lobes 2, linear. Styles 2, very long, 
flattened at the base. Fruiting-spikes sometimes elongated and exceeding 
the leaves, sometimes short and sessile among the leaves. Drupes sessile 
or nearly so, clavate, spreading or pendulous, 4, in. long —Students’ Fl.

A distinct species, easily recognized by the narrow-ovate or elliptic-oblong acute 
leaves, which are often cuneate at the base, and coarsely dentate.
