[Haloragis. 
is certainly most closely allied to it ; but the fruit is very much larger in the New Zealand 
plant. 
4. H. micrantha, Br. ; — Id. tenella, Brongn. ; FI. N. Z. i. 63. Small, 
slender, tufted, perfectly glabrous ; stems and branches filiform, ascending 
or erect, 2-6 in. high, running out into leafless racemes. Leaves few, i— | 
in. long, all opposite, subsessile, broadly ovate, subacute, with very few shal- 
low crenatures on each side, glabrous. Flowers few, very minute, scattered 
along the naked filiform tips of the branches ; pedicels very short. Nut 
minute, oblong, 8-ribbed. Stigmas plumose. — Goniocarpus citriodorus, A. 
Cunn. — G. tenellus, Brongn. 
Common in rather moist and dry places in various parts of the Northern Island. 
Sdiddle Island : Aglionby plains, Munro. Common in Tasmania, Southern Australia, the 
Eastern Himalaya, hilly parts of East Bengal, and in Japan. This is the Goniocarpus citrio- 
dorus of A. Cunningham, but I have never perceived any smell of lemons ; possibly he dried 
it with Micromeria. 
2. MYRIOPHYLLUM, Vaillant. 
Water or marsh plants, with slender, terete, sparingly branched stems. 
Leaves usually whorled, entire toothed or pinnatifid, the submerged often 
capillaceo-multifid, the uppermost more entire, often opposite or alternate. 
Flowers small, in the axils of the upper leaves, almost sessile, uni- or bisexual. 
— Calyx-tube in the male 0, in the female ovoid or 4-gonous, limb 4-toothed 
or truncate. Petals 0 in the female flower, in the male 4, membranous, deci- 
duous. Stamens 4 or 8, filaments short ; anthers linear. Ovary 4-celled ; 
styles 4, very short, or 0 ; stigmas often plumose. Fruit usually separating 
into 4 small, hard, indehiscent, 1-seeded nuts ; testa membranous ; albumen 
fleshy ; embryo terete. 
A very widely-diffused genus in both tropical and temperate regions. The species have 
wide ranges in their several zones, but those of the southern regions are hardly the same 
with the northern. The foliage is very variable ; the upper leaves in the two first New Zea- 
and species are sometimes as much divided as the lower. 
Upper leaves whorled, short and broad, serrate 1. M. elatinoides. 
Upper leaves whorled, narrow-linear, nearly entire 2. 31. vuriafolium. 
All the leaves pectinate-pinnatifid. Fruit large 3 .31. robustum. 
All the leaves opposite, linear, narrow, entire 4. M. pedunculatvm. 
1. M. elatinoides, Gaudicliand ; — FI. N. Z. i. 63. Stems 6 in.-3 ft. 
long, depending on the depth of the water. Leaves whorled, usually 4-nate, 
the lower pectinately pinnatifid, 1-2 in. long, the upper much smaller, sessile, 
oblong, obtuse, serrate. Flowers small, white ; female with two linear entire 
or serrate bracts. Stigmas plumose. Fruit of 4 minute, oblong, terete, 
smooth nuts. — M. propinquum, A. Cunn. 
Still waters throughout the islands, ascending to 3000 ft. Abundant in Tasmania, Aus- 
tralia, and the lakes of the Cordillera from the equator to Chili and the Falkland Islands. 
2. M. variaefolium, Hook. f. in Ic. VI. t. 289 ; — FI. N. Z. i. 65. Habit 
of the last, but leaves in whorls of 5-7, the lower multifid or pectinate-pin- 
natifid, the upper very narrow linear, ^-1^ in. long, quite entire or serrate. 
Flowers and fruit very small, like those of M. elatinoides , but the bracts are 
much shorter than the nuts.
