(Handbook) ; Craigieburn Mountains, Canterbury, Cockayne !

that can be referred to the species. 
6. G. dentata, 7. Kirk in Trans. N.Z. Inst. xxvii. (1895) 346. 
—Forming extensive patches in watery subalpine localities. Rhi- 
zome stout, much branched, clothed with the bases of the cold 
leaves. Leaves numerous, densely tufted, 1-3in. 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. Males 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 some- 
times elongated and exceeding the leaves, sometimes short and 
sessile among the leaves. Drupes sessile or nearly so, clavate, 
spreading or pendulous, #,in. long.—Students’ Fl. 154. G. pro-
