171 
Corolla 1-2 in. long, blue, pubescent. Berry \ in. diam .—Lobelia physa- 
loides, A. C. ; Hook. Ic. PL t. 555-6. 
Northern parts of the Northern Island, from Wangaroa to the North Cape, Cunning- 
ham , Dieffenbach, etc. 
3. LOBELIA, Linn. 
Erect or ascending, generally glabrous, milky kerbs. Leaves alternate. 
Blowers usually racemose or axillary. — Calyx-lobes 5. Corolla-tube split to 
the base down the back, rarely of 3 petals, 2-lipped, upper lip of 2 lobes (or 
two petals when separate), oue on each side the fissure, lower with 3 spread- 
ing lobes. Anthers connate, 2 upper often pilose at the tip. Ovary 2-celled; 
style undivided or 2-lobed. Capsule membranous or coriaceous, usually de- 
hiscing by 2 valves at the top. 
A very large genus, found in all parts of the world. The corolla is generally split but 
once to the base, but in L. Roughii , the two dorsal petals are free to the base, and it is hence 
split thrice to the base. 
Erect, glabrous. Stems flat or 3-gonous. Flowers small, axillary . . . 1. L. anceps. 
Small. Stems very short. Leaves broad, with deep teeth. Flowers on stout 
peduncles, large 2. L. Roughii. 
1. L. anceps, Tliunberg ; — FI. N. Z. i. 158. A branched, leafy, erect 
or ascending, glabrous, subsucculent herb, 6-12 in. high. Stems flattened, 
trigonous, sometimes winged. Leaves 1-3 in. long, variable in shape, 
spathulate linear obovate or oblong, entire sinuate or toothed, narrowed 
into decurrent petioles. Blowers small, | in. long, pale blue, on short, soli- 
tary, axillary peduncles. Ovary elongated. Capsule linear or clavate, often 
\ in. long. 
Northern and Muddle Islands: abundant in wet places, as far south as Banks’s Pen- 
insula, Banks and Solander. Kermadec Islands : M‘ Gillivrag, a large leaved form. 
2. L. Roughii, Hook. /., n. sp. A very short, glabrous, scapigerous 
plant, full of acrid, milky fluid. Stems branched, very short, slender, tortu- 
ous amongst shingle, leafy at the top. Leaves in. long, shortly petioled, 
obovate, very deeply toothed or lobed, the sinus round, coriaceous, nerveless. 
Peduncles stout, erect, axillary, 1-flowered. Calyx-tube globose ; lobes linear, 
coriaceous, obtuse, growing out as the fruit ripens. Corolla-tube 3-partite, 
about as long as the calyx-lobes, its lobes obtuse, short. Anthers glabrous. 
Capsule ovoid, globose, leathery, ^ in. long, dehiscing by cartilaginous valves 
between the calyx-lobes. 
Middle Island : Nelson mountains, Rough ; Wai-au-na valley, alt. 3000 ft., and Wairau 
Gorge, alt. 4-6500 ft. on shingle, Travers. A very curious little species, its habit is that 
of Wahtenbergia cartilaginea. 
4. PBATIA, Gaudickaud. 
Small, creeping, herbaceous plants, wuth prostrate stems. Leaves small, 
broad, rounded or oblong, sinuate or toothed. Peduncles axillary, often 
long, single-flowered. — Blowers the same as in Lobelia. Bruit fleshy, inde-
