Hydrocotyle .] 
xxxiri. umbellifera:. 
87 
shortly pedicelled. Fruit glabrous, in. diam., rather turgid, pale brown. 
Carpels rounded on the back, with 1 obscure rib on each face. 
Abundant throughout the islands in wet places, Banlcs and Solander, etc. Very near the 
Indian If. rotundifolia, Roxb., the Australian H. vagans , H. f., and the American H. Bon- 
plandi , Rich., but the leaves are less deeply lobed. 
9. H. moschata, Forst. ; — FI. N. Z. i. 83. Hispidly pilose tomentose 
or glabrescent ; stems rather slender, tufted, 2-6 in. long. Leaves % in. 
diam., reniform or orbicular with usually an open sinus, 5-7-lobed, generally 
very distinctly, but never to the middle, lobes acutely toothed, rather coria- 
ceous, and generally hispid on both surfaces ; petioles short, i-1 in. long ; 
stipules large, membranous. Peduncles very variable, as long as the petioles 
or shorter or 0. Umbels few- or many-flowered. Fruit minute, in. diam., 
generally crowded, glabrous, turgid. Carpels with 1 rib on each face, acute 
at the back. 
Abundant in moist places throughout the islands, Banks and Solander, etc. I suspect 
the Tasmanian //. hirta, Br., to be one form of this, the Tristan d’Acunha H. capitata, 
Thouars, and the Chilian IT. Bonplandi, Rich., others. In some New Zealand specimens the 
leaves are scarcely lobed, and the teeth obtuse. 
10. H. microphylla, A. Gunn. ; — FI. N. Z. i. 84. Glabrous or sparingly 
hairy ; stems almost filiform, often stout at the very base, 1-4 in. long. Leaves 
i— in. diam., orbicular-reniform, with a closed sinus, 5-7-lobed, lobes shallow, 
obtusely 3-4-crenate; petioles J in. long ; stipules rather large. Peduncles 
as long as or shorter than the petioles, slender. Umbels very small, 3-5- 
flowered. Flowers almost sessile. Fruit very minute, brown, glabrous, ^ in. 
diam. Carpels rather turgid, with an indistinct rib on each face, obtuse at 
the back. 
Not uncommon in moist places, from the Ray of Islands to Nelson, Travers ; but easily 
overlooked, from its small size. 
2. POZOA, Lagasca. 
Small herbs, with radical leaves and scapes, or, like Hydrocotyle , with 
creeping stems and fascicled simple or 3-5-foliolate leaves. Umbels simple. 
Involucral leaves free or connate, forming a toothed or lobed cup. Flowers 
small, sometimes unisexual. — Calyx 5-toothed. Petals valvate, without in- 
flexed tips. Fruit almost tetragonous, the carpels dorsally compressed rounded 
flat or concave, more or less evidently 5-ribbed. 
A small temperate South American, Tasmanian, and New Zealand genus ; the species have 
often a rank odour when bruised.
