152 HALORAGEZ.. [Myriophyllum. 
usually 5 in a whorl, 1-2 in. long, all deeply pectinately pinnatifid ;. 
upper rather coarse, usually crowded and overlapping ; submerged 
leaves not often seen, when present with longer capillary segments. 
Flowers rather large, 1-1 in. long, solitary or rarely in pairs in the 
axils of the floral leaves, with a pair of minute laciniate bracts at 
the base of each. Calyx-lobes present in both sexes, deltoid, 
jagged. Petals in the males only, linear-oblong. Stamens 8. 
Stigmas usually 4, plumose. Nuts 4, ¢in. long, laterally com- 
pressed, usually with a single or double row of tubercles down the 
back, but sometimes smooth and rounded.—Kirk, Students’ Fl. 
151. M. variefolium var. b, Hook. f. Fl. Nov. Zel. 1. 64. 
NorruH Isuanp: In swamps from Ahipara to the Upper Waikato, but often 
local; apparently rare further south. Hawke’s Bay, Colenso! Mungaroa, 
Wellington, Kirk! Souru Isnranp: Awatere, Kirk ! Moutere, Nelson, 7. #’. C. ; 
near Westport, Townson! Hokitika, Tipler. December—February. 
This is seldom found in lakes or streams, and is a marsh plant rather than 
a true aquatic. It often covers large stretches in swamps that are quite dry in 
summer. 
4. M. pedunculatum, Hook. f. Fl. Tasm. 1. 123, t. 23B.— 
Stems short, simple or sparingly branched, tufted, 1-3 in. high, 
usually forming broad matted patches. Leaves opposite, minute, 
4-1 in. long, linear or linear-spathulate, quite entire, rather fleshy. 
Flowers minute, usually dicecious ; males shortly stalked or sessile ; 
females sessile; bracts 2 at the base of each flower, minute, linear. 
Calyx-lobes 4, very minute. Petals 4, wanting in the female 
flowers. Stamens 8. Stigmas 4, plumose, recurved. Carpels 4, 
small, oblong, minutely rugose.—Handb. N.Z. Fl. 67; Kirk, Stu- 
dents’ Fl. 151. 
NortH anp SoutH Istanps, SrEwart Isutanp: From Cape Maria van 
Diemen southwards, but far from common. Sea-level to 2000 ft. Decem- 
ber—February. Also in Australia and Tasmania. 
M. verrucosum, Lindl. in Mitch. Trop. Austral.; Benth. Fl. Austral. ii. 488, 
is included by Mr. Kirk in the ‘‘ Students’ Flora” as a native of New Zea- 
land, on the authority of specimens gathered by himself near Tauranga Harbour. 
These are very imperfect, having no flowers and few withered fruits; but, having 
compared them with authentic examples of M. verrucoswm from Australia, I can 
state definitely that they are not referable to that species. They only differ 
from M. intermediwm in the upper leaves being pinnatifid, and until more 
complete specimens are obtained are best considered as a form of that plant. 
3. GUNNERA, Linn. 
Stemless herbs with creeping rhizomes, often forming broad 
matted patches. Leaves all radical, petiolate, ovate- or rounded- 
cordate, coriaceous and fleshy. Flowers small, unisexual or rarely 
hermaphrodite, in simple or branched spikes or panicles. Male 
flowers: Calyx-tube imperfect or wanting; lobes 2-3, minute. 
Petals 2-3 or wanting. Stamens 2-3; filaments filiform; anthers 
large. Females: Calyx-tube ovoid; lobes 2-3, small. Petals 2-3
