XXXIII. UMBELLIFERiE. 
[Pozoa. 
cordate at the base, \ in. diam., obscurely 3-5-lobed, coriaceous, glabrous ; 
stipules obsolete ; petiole very stout. Scape short, stout ; involucral leaves 
linear-oblong, connate at the base. Calyx-teeth very unequal. Fruit not 
seen. 
Middle Island : Otago, lake district, alpine, Hector and Buchanan. 
2. P. Haastii, Hook./., n. sp. Very variable in size. Rhizome stout 
or slender, sometimes as thick as the little finger, often sending out creeping- 
suckers, or prostrate leafing and flowering branches 6-10 in. long. Leaves 
1-1£ in. broad, coriaceous, bright-green and glossy, reniform or orbicular, 
rounded or deeply lobed at the base ; margin almost cartilaginous, crenate- 
lobed; lobes very broad, shallow; petioles stout, 1-3 in. long; stipules 
ciliate or laciniate. Umbels many-flowered, rising from the suckers in the 
axils of shortly petioled, 3-4-lobed leaves, shortly peduncled. Involucral 
leaves broadly linear, obtuse, longer than the pedicels. Pedicels | in. long, 
generally 4 times as long as the shortly oblong fruit. 
Middle Island: Hopkins river, 4000 ft.; Mount Darwin, "Waitaki river, and Hunter 
river, on shingle, alt. 3500-4500 ft., Haast. The leaves vary in being sometimes deeply 
lobed, at others rounded and not lobed at all at the base. 
3. P. reniformis. Hook. f. PI. Antarct. i. 15. t. 11. Small, per- 
fectly glabrous, shining, bright green. Rhizome slender, creeping or sending- 
out stolons. Leaves | — § in. diam., coriaceous, reniform or orbicular with a 
rather open sinus, crenate-lobate ; petioles stout, 1-2 in. long ; stipules acu- 
minate, quite entire. Peduncles shorter than the leaves. Involucral leaves 
linear, obtuse, membranous, with a green nerve. Umbels 6-10-flowered. 
Flowers very small, shortly pedicelled. Fruit glabrous, linear-oblong, longer 
than its pedicel, in. long. 
Xford Auckland’s group : in clefts of rocks, J. T). H. Very near indeed to P. Fra - 
ffosia, P. Muell., of the "Victoria Alps, which has ciliate stipules. 
4. P. trifoliolata. Hook. f. FI. N. Z. i. 85. t. 18. Very slender, 
glabrous. Stem 2-6 in. long, filiform, creeping. Leaves 3-foliolate; leaflets 
with the slender petioles |in. long, obovate-cuneate, unequally 3-4-lobed; 
lobes obtuse, apiculate, narrowed into a petiole 1-3 in. long ; stipules very 
obscure, ciliate. Peduncles shorter than the petioles, slender. Umbels 3-6- 
flowered; involucral leaves subulate, small, 2-5 -fid. Flowers minute, almost 
sessile ; petals acute. Fruit very small, Dg in. long, dark-brown or pale- 
yellow. Carpels almost terete at the back. 
Var. j8. tripartita ; very small, with a few bristly hairs here and there ; leaflets sessile, 
more coriaceous, 1 in. long. 
I'fforthern Island: Totara-nui, Banks and So/ander ; stony and rocky places on the 
east coast and Euahine range, Co/enso. Var. /3. Crags on Titiokura, Colenso. 
5. P. hydrocotyloid.es. Hook. /., n. sp. Glabrous, stout, tufted. 
Stems creeping and rooting by stout runners 3-5 in. long. Leaves in. 
diam., orbicular-reniform, coriaceous, 3-5-foliolate ; leaflets sessile, broadly 
obovate-cuneate, 3-5-lobed or -crenate at the tip ; petioles f-1 in. long, stout ; 
stipules subulate, entire or ciliate. Peduncles as long as the leaves, solitary 
from the nodes of the stem, or several at the apex of a leaf-bearing scion. 
Umbels as in P. Rough'd , but much smaller.
