Ob s . Ubslia rotundifolia, Banks et Sol. MSS. et Io., 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 axiUary pedunculate 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, which is found in aU temperate and tropical parts of the globe,
many species inhabiting New HoUand aud Tasmania. (Named in honour of Matthias de L'Ohel, a Flemish botanist
and autkor.)

H ,ab. N o rth e rn and Middle Islands ; abundant as far south as B a n ts ’ Peninsula, B a n k s a n d 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. Unear-lanceolate, spathulate or much elongated and Ugulate, sharp, entire or waved and toothed.
Peduncles solitary, axillary, short, 2 -4 lines long, much shorter than the leaves they rise amongst, but rarely the
branches become racemose at the end, the upper leaves being reduced to bracts below the peduncles. Flowers inconspicuous.
Ovarium narrow, very long when ripening. Corolla short, pale blue. Capsule variable in size, i inch
long,—This species abounds in temperate Australia and Tasmania, Juan Fernandez. ChiU, 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 ( i . alata) is named Z. angulata by Cunningham himself.

H ab . N o rth e rn Island. H aw k e ’s Bay, in m u d d y places, Colenso.
A very minute species, resembling a Fratia in habit, and the fruit being unknown it may belong to that genus.
Stems stout, creeping, branched, 3 -3 inches long. Leaves 3 lines long, sessUe, oblong, sharp, deeply toothed, smooth
or pilose. Flowers sessüe, pale, much longer than the leaves. Ovmy haiiy. Calyx lobes recurved. Corolla lobes
acuminate. Stamens inserted on the corolla. Anthers perfectly smooth; filaments joined together into a tube
below the anthers.—This species resembles the Z. irrigua of Tasmania.
Ob s . 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 ; hmb of three to five segments.
Corolla bell-shaped, generally five-cleft. Stamens five ; the filaments uot dilated at the base. Stigma simple or
three-cleft. Capsule with three cells, opening at the top by three valves. Seeds very numerous.—A very large
genus, found in the tropics and warmer temperate zones of both hemispheres ; especially abundant at the Cape of
Good Hope. The species are often extremely variable, the New Zealand aud Australian ones especially. (Named
in honoui- of G. Wahlenberg, an eminent Swedish botanist.)

This is perhaps the most variable annual in New Zealand, where it is well kuown as a common and troublesome
garden-weed. I t is a very widely-diffused plaut, being abundant in Australia and Tasmania, and India ; and found
also in New Caledonia. Stems simple, branched from the base, or throughout their whole length, in a paniculate manner;
the branches terminating in long, generally slender peduncles ; smooth or hispid with stiff white hairs, leafy or xvith
very few leaves. Stems 1 inch to 2 feet high, generally slender, angled or striated. Leaves usually linear, sessile, sharp,
toothed or waved, or crisped, or quite entire, raai'gin often cartilaginous aud white ; lower ones sometimes spathxdate,
toothed, aud petioled. Floicers extremely variable in number, size, and length of the corolla, calyx lobes, and ovarium,
three and five being the prevailing numbers of lobes and stamens, and the length from 3 lines to t inch. Corolla
beU-shaped, wliite or blue, usually small, 2 lines or 4 inch long, sometimes large, especially in Tasmania, where
it forms a large blue bell f inch across the 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 sinall flowers, and globose capside, but I find it passing into the larger state of the
plant, as Mr. Brown has indicated, by referring Tasmanian specimens of it to his 7J'. gracilis. The ilowers arc
never nearly so large in New Zealand as in Australia.
