240 Transactions, — Botany. 
closely anastomosing; petioles 14-8 inches long; stipules large, mem- 
branous, veined, entire. Pedunele 1-14 inches long, slender (two are often 
united below near base, and thus become bi-peduncled), sometimes largely 
pilose. Involucral leaves two, sub-orbicular or orbicular-ovate, sessile and 
half-clasping, glabrous, veined, purple stained or margined, very mem- 
branous. Flowers single, sessile (rarely two together, and when so then 
one is shortly pedicelled), petals rather large, ovate, sub-acute, purple, 
reflexed. Fruit large, sub-orbicular, compressed, 2 lines diameter, obso- 
letely 8—4-ribbed, tops purplish with a few loosely scattered hairs. 
Hab. Wet sides of slopes, gullies near Norsewood, County of Waipawa ; 
1884: W.C. But not common. 
Obs. A species having pretty close affinity with H. asiatica, Linn., but 
differing in several particulars. 
8. Hydrocotyle intermixta, sp. nov. 
Plant very small; stems short, creeping and rooting interlaced under- 
ground. Leaves orbicular with a narrow deep sinus, 8-4 lines diameter, 
thickish, much veined, dark green, sparsely pilose on both sides with long 
succulent scattered hairs, 5-6-lobed, lobes short, broad, sub-tri-laciniate, 
cut, obtuse; petioles 4-5 lines long; stipules delicately membranous, reti- 
culated, sharply laciniate. Flowers in small globose heads, 9-10 (sub 12), 
minute, red, sessile, petals incurved, obtuse; styles short; peduncles 7-8 
lines long, erect, striate ; involucral leaves small, obovate, obtuse. Fruit 
very small, shortly pedicelled, glabrous, turgid, broader above than below, 
shining, dark brown ; earpels sharply keeled on back, 1 rib on each face, 
and a deep hollow between the two lateral ridges. 
Hab. On dry open hills near Matamau, Seventy-mile Bush, County of 
Waipawa; forming thick little patches among short grasses and mosses, 
and other small plants, scarcely visible without close search; 1880-84:

Genus 2. Panax, Linn. 
1. Panax microphylla, Col.* 
Flowers axillary, in 2-4 small umbellate panicles, conjoined at base and 
wearing a fascicled appearance, each sub-panicle containing 2-4 flowers—in 
all 8-14, small and inconspicuous, 14 lines diameter, pedicelled, each 
pedicel surrounded by many minute stipelle ; petals broadly ovate, sub- 
acute, darkish-red on the outside greenish-red within, spreading, slightly
