XXVII. HALORAGEAi.

Common in still water throughout the islands, as far south as Canterbury. Also found 
iu Tasmania, Australia, and South Ameriea. 
3. M. robustum, Ilook.f., n.sp.; — M. varupfolium , /3, FI. N. Z. i. 64. 
Stems robust. Leaves 1-2 in. long, 5-7 in a whorl, all pectinately-pinnatifid. 
Flowers and nuts much larger than in the preceding species, the latter nearly 
i in. long, tumid, short, rounded at the back, smooth or obscurely tubercled, 
bracts very short. 
Northern Island, Colenso. A robust species, of which I have imperfect specimens, 
full of fruit, which is as large as in the Indian M. tuberculatum, but the nuts are more 
rounded, and the foliage is coarse and more crowded. It much resembles some states of the 
European M. verticillatum. I do not recognize it amongst the Australian and American 
species. 
4. M. pedunculatum, IIoolc. f. FL Tasm. i. 123. t. 23 B. Small, 
tufted, erect, slender, simple or sparingly branched, 2-4 in. high. Leaves oppo- 
site, narrow linear, quite entire or obscurely toothed, | in. long. Flowers 
minute, sessile or shortly pedicelled. Stamens 8. Styles recurved ; stigmas 
plumose. Nuts ovoid, somewhat wrinkled. 
Middle Island : moist places, Canterbury plains, Sinclair and Haast. Found also in 
Tasmania and Victoria, where the leaves sometimes become broad and flat. 
3. GUNNEEA, Linn. 
Stemless herbs, usually growing in swamps or boggy places, with stout or 
slender creeping or subterranean rhizomes. Leaves petioled, radical. Scapes 
bearing small, racemose or panicled, unisexual, rarely bisexual, flowers. — Male 
fl. : Sepals 2 or 3. Petals 2 or 3 or 0. Stamens 2 or 3, opposite the petals, fila- 
ments slender ; anthers large, often tetragonous. Female fl. : Calyx-tube 
ovoid, lobes 2 or 3, often toothed. Petals 2 or 3 or 0. Stamens 0. Ovary 
1-celled ; styles usually 2, linear subulate or filiform, covered with stigmatic 
papilla 1 * * * 5 ; ovule solitary, pendulous. Fruit a small, rather fleshy drupe. 
Seed filling the cavity of the drupe, to the walls of which the membranous 
testa often adheres ; albumen fleshy and oily ; embryo very minute, broadly 
pyriform or cordate. 
An almost exclusively southern genus, scattered over the Australian, Malayan, New Zealand, 
Pacific, and South American islands, also found in South Africa and in the Andes, as far 
north as the Gulf of Mexico. The Chilian species is noted for its immense leaves, some- 
times 6 ft. across. The New Zealand species have long filiform styles, and no petals. 
Leaves orbicular-reniform. Flowers lax, subpanicled. Drupe very 
small, ovoid 1. G. monoica. 
Leaves reniform or cordate. Flowers in a dense spike. Drupe oblong. 2. G. densiflora. 
Leaves oblong- or ovate-oblong. Flowers spicate. Drupe much larger, 
obovoid 3. G. prorepens. 
1. G. monoica, Raoul , Choix xv. t. 8 ; — Fl. N. Z. i. 65. Glabrous or 
minutely hairy ; rhizome creeping, tufted, forming matted patches. Leaves 
reniform or orbicular, ■§— J in. diam., lobed and crenate, or crenate only, both 
surfaces glabrous or covered with scattered small hairs, petiole 2 in. long, 
pilose, rarely glabrous. Panicle longer or shorter than the leaves, very slender, 
branched, rarely simple. Flowers sparse, males with long filaments ; bracts
