3. L. Roughii Hook. f. Handb. N.Z. Fl. (1864) 171.—A small perfectly 
glabrous perennial herb 2—5in. high, full of white acrid fluid. Stems 
very slender, creeping, branched, tortuous among shingle ; branches short, 
leafy at the tips. Leaves alternate, $-lin. long; blade broadly oblong 
or obovate to orbicular, narrowed into a broad flat petiole, coarsely and 
deeply toothed or lobed with a rounded sinus between the teeth, thick 
and coriaceous; main veins 5-7, spreading from the base of the leaf. 
Peduncles stout, erect, axillary, 1-flowered; at first shorter than the 
leaves, but lengthening as the fruit ripens, and sometimes reaching 2 in. 
or more. Flowers din. long. Calyx globose ; lobes linear, obtuse, cori- 
aceous, lengthening as the fruit ripens. Corolla equalling the calyx-lobes, 
3-lipped ; the two dorsal petals (upper lip) being free from one another 
to the base; lower. lip 3-lobed about 4-way down. Anthers glabrous. 
Capsule $-4in. long, broadly ovoid, coriaceous. Seeds very numerous.—

A most distinct species, quite unlike any other. It is remarkable for the corolla 
being twice split to the base at the back, so that the flower is 3-lipped. 7 
4. ISOTOMA Lindl. \¢ 2. 
Herbs of various habit. Leaves alternate, entire or toothed or 
pinnatifid. Flowers axillary or in terminal racemes. Calyx-tube adnate 
to the ovary’; limb 5-partite. Corolla-tube cylindrical, entire or very 
shortly slit on the upper side; limb spreading, with 5 nearly equal lobes. — 
Stamens inserted about the middle of the corolla-tube ; filaments connate 
above ; anthers similar to those of Lobelia, the 2 lower ones tipped with 
one or several short bristles, the 3 upper naked. Ovary 2-celled; ovules 
numerous ; stigma shortly 2-lobed. Capsule 2-celled, loculicidally 2-valved 
within the calyx-lobes. Seeds numerous. : 
A small genus of 6 or 8 species, most of them natives of Australia. It differs 
from Lobelia in the corolla-tube not being split to the base at the back, and in the 
stamens being affixed to the middle of the tube. The single species found in New 
Zealand is plentiful in south-east Australia and Tasmania.
