Obs. Lobelia roiundifolia, Banks et Sol. MSS. et Ic., has lobules to the base of the leaves, which I do not find
in my specimens, and I therefore refrain from quoting it as a synonym.

The two New Zealand species are herbaceous plants, with axillary peduuculate or subsessile flowers, differing
from Pratia chiefly, if not wholly, in the fmit being capsular, opening by valves (not fleshy and scattering the seeds
by decay of the pericarp).—This is a very large genus, wliich is found in all temperate and tropical parts of the globe,
many species inhabiting New Holland and Tasmania. (Named in honour of Matthias de VObel, a Flemish botanist
and author.)

H ab. Northern and Middle Islands; abundant as far south as Banks’ Peninsula, Banks and Solander,
etc.
An erect or decumbent, simple or branched, smooth herb, with weak, flattened, three-angled, winged stems
and branches, a foot or so high. Leaves 1-3 inches long, narrowed into rather broad decurrent petioles, very
variable in shape, linear-lanceolate, spathulate or much elongated and ligulate, sharp, entire or waved and toothed.
Feduncles solitary, axillary, short, 3-4 lines long, much shorter than the leaves they rise amongst, but rarely the
branches become racemose at tbe end, the upper leaves being reduced to bracts below tbe peduncles. Flowers inconspicuous.
Ovarium narrow, very long when ripening. Corolla short, pale blue. Capsule variable in size, 4 inch
long.—This species abounds in temperate Australia and Tasmania, Juan Fernandez, Chili, and the Cape of Good
Hope. Mr. Colenso assures me that Lobelia angulata is the same as his L. littoralis, but in Herb. Hook, this
species (L. alata) is named L. angulata by Cunningham himself.

H ab. Northern Island. Hawke’s Bay, in muddy places, Colenso.
A very minute species, resembling a Pratia in habit, and the fruit being unknown it may belong to that genus.
Stems stout, creeping, branched, 3-3 inches long. Leaves 2 lines long, sessile, oblong, sharp, deeply toothed, smooth
or pilose. Flowers sessile, pale, much longer than the leaves. Ovary haiiy. Calyx lobes recurved. Corolla lobes
acuminate. Stamens inserted on the coroUa. Anthers perfectly smooth; filaments joined together into a tube
below tbe anthers.—This species resembles tbe L. irrigua of Tasmania.
Obs. Lobelia submersa, A. Cunn. Prodr., is Glossosiigma elatinoides, Benth. (see Nat. Ord. Scrophulariaceoe),
according to a specimen in Herb. Cunningham in Mr. Heward’s possession, which differs in no way from the description
in the ‘ Prodromus Floræ Novæ Zelandiæ,’ except that I find no hairs on any part.

Smooth or pubescent, erect, simple or branching herbs. Calyx tube obovate ; limb of three to five segments.
Corolla bell-sbaped, generaUy five-cleft. Stamens five ; the filaments uot dilated at the base. Stigma simple or
three-cleft. Capsule with three ceUs, opening at the top by tbree valves. Seeds very numerous.—A very large
genus, found in tbe tropics and warmer temperate zones of both hemispheres ; especiaUy abundant at the Cape of
Good Hope. The species are often extremely variable, tbe New Zealand and Australian ones especiaUy. (Named

H ab. Throughout the Islands; abundant in dry and exposed situations. Banks and Solander, etc.
(Cultivated iu England.)
This is perhaps the most variable annual in New Zealand, where it is well known as a common and troublesome
garden-weed. It is a very widely-difliised plant, being abundant in Australia and Tasmania, and India ; and fonnd
also in New Caledonia. Stems simple, branched from tbe base, or throughout their whole length, in a paniculate manner;
the branches terminating in long, generally slender peduncles ; smooth or hispid with stiff w'hite hairs, leafy or with
very few leaves. Stems 1 inch to 2 feet high, generally slender, angled or striated. Leaves nsnally linear, sessile, sharp,
toothed or waved, or crisped, or quite entire, moi-giu often cartilaginous and white ; lower ones sometimes spathulate,
toothed, aud petioled. Flotcers extremely variable in number, size, and length of tbe corolla, calyx lobes, aud ovarium,
three and five being tbe prevailing numbers of lobes and stamens, and the length from 3 lines to t iuch. Corolla
bell-shapcd, wliite or blue, usually small, 3 lines or 4 inch long, sometimes large, especially in Tasmania, where
it forms a large blue bcU f inch across tbe mouth. Capsule extremely variable in size and shape, 1 line to 4 iuch
long, nearly globose or oblong, or linear-obconic.—The variety capillaris looks very distinct at first sight, from its
extremely slender habit, very small flowers, and globose capsule, but I find it passing into the larger state of the
plant, as Mr. Brown has indicated, by rcfcrring Tasmanian specimens of it to bis 77’ gracilis. The flowers arc
never nearly so large iu New Zealand as iu xVnstralia.
