Gen. I. UTEICULAUIA, L.
Calyx 2-phyUus; labiis æqualibus, indivisis. Corolla personata; labio inferiore basi calcarato. Stamina
2 ; filamentis apice intus antberiferis. Stigma 2-labiatum.
A veiy large genus, whose species abound in watery and marshy places of both hot and cold climates, sometimes
in wet moss ; many kinds float by means of minute bladders attached to the stems and leaves, some terrestrial
kinds are likewise thus provided. Calyx of two leaves. Corolla two-lipped. Stamem two. Ovamj globose. Stigma
discoid, cup-shaped, or two-lipped. (Name from utrimlm, a little bladder.)
1. RixicxAanaNovm-Zelandim, Hook, fil.; radicibus vesiculiferis, vesiculis pedicellatis, scapo simplici
erecto apice 1-4-floro, foliis deciduis radicalibus lineari-lanceolatis carnosuhs 1 -nerviis, bracteolis late ovatis
obtusis, pedicellis brevibus, calycis labio superiore orbiculari retuso v. bilobo multinervi inferiore cochleato
obscure 3-dentato, corollæ labio superiore cuneato retuso inferiore late securiformi margine integerrimo,
calcare porrecto obtuso.
H a b . Northern Island. Wet rocks at Palliser Bay, Colenso.
A minute slender herb, with fibrous roots, covered with pediceUate bladders, and a simple thread-like scape,
bearing three to four flowers. Leaves few, aU radical, linear-lanceolate. Bracts broadly ovate, blunt. Flowers
white, shortly pedicellate. Calyx two-lipped ; upper Up orbicular, retuse, or two-lobed ; lower concave, obscurely
three-toothed. Corolla two-lipped ; upper lip wedge-shaped, retuse ; lower broadly axe-shaped, margin entire ; spur
projecting, blunt.—Nearly allied to the Tasmanian TJ. dichotoma, but much smaller ; also near U. monanthos, but
the spui* is longer, and the scape bears more flowers.
2. XJtricularia Colensoi, Hook. fil. ; omnia Ü. Nova-Zelandiæ sed corollæ labio superiore lineari-
oblongo bilobo inferiore late cuneato 3-lobo, lobo medio retuso, disco 3-gib
H a b . Northern Island. East coast, <
My only specimens are preserved in camphorated spirits of wine, aud hence not easily examined ; but they
appear to differ conspicuously from the former in the linear two-lobed upper lip, and broadly wedged-sliaped three-
lobed lower, which has three swellings on the disc.
3. TJtricularia protrusa, Hook. fil. ; natans, caule elongato, foliis capillaceo-multipartitis vesiculiferis,
scapo erecto valido 2—4-floro, sepalis ellipticis, coroUæ labio superiore 3-lobo inferiore subquadrato marginibus
recurris fauce protrusa, calcare brevi obtuso.
H a b . Northern Island. Bogs, Bay of Plenty, Colenso,
The specimens were preserved with TJ. Colensoi, and the character may require much correction ; it is the
only long-stemmed floating TJtricularia I have seen from New Zealand. Stems a span long, covered with capillary
leaves and Httle bladders. Scape stout, transparent, with a few yellow flowers. Upper lobe of corolla three-lobed ;
lower broad, with the disc bulging out and margins recurved. Spur short, blunt.

Gen. I. SAMOLUS, L.
Calyx semi-superus, 5-fidus. Corolla subcampanulata, 5-fida. Stamina 5 fertilia lobis corollæ
opposita; 5 sterilia alterna. Capsula semi-infera, semi-5-valvis, 1-locularis. Semina plurima, placentæ
centrali liberæ affixa.
The only New Zealand species is a very variable, smaU, white-flowered, herbaceous, littoral plant, which abounds
on aU the New HoUand and Tasmanian coasts, and in South ChUi. Stems branching, leafy, terete, prostrate, 6-1Ü
inches long. Leaves fleshy, linear-spathulate or lanceolate, very variable in length and breadth, sharp or blunt, 2
lines to Ig inch long. Floicers solitary, white, axülary, on one-bracteate pedicels longer or shorter than the leaves.
Calijx half-superior, five-lobed; lobes sharp. Corolla shortly beU-shaped, with five rounded lobes. Stamens lew,
five fertile opposite the lobes of the corolla. Capsule one-ceUed, with five short valves, and many seeds attached to
a free central placenta.—Of the other species of this geuus one is found almost aU over the world, and a few others
are Australian and South American. (Name, Druidical, according to Phny, for some marsh healing plant.)
1. Samolus littoralis, Br. ; caule tereti ramoso folioso, foliis spathulatis lanceolatisve, calycis laciniis
acutis. Br. Frodr. etc. Sheffieldia repens, Linn. Suppl.
H a b . Abundant throughout the Islands, on all the coasts, Banks and Solander, etc.
N a t . O r d . L X V IL PLANTAGINEÆ, Juss.
Gen. I. PLANTAGO, L.
Flores hermaplicoditi. Capsula 2-4-locularis.
Herbaceous plants, with radical leaves, and scapes bearing few flowers, or long or short spikes of often densely
packed hermaphrodite flowers. Sepals four. Corolla of a scarious texture, persistent, with a four-lobed spreading
limb. Stamens fom*, on long exserted filaments. Ovary sessile, two- to four-locular. Ovules few or mauy, pellale.
Style one, exserted, filiform, hairy. Capsule bursting liorizontally across the middle. Seeds attached to either face
of a longitudinal dissepiment, sessUe, peltate.—A very large genus, found in aU parts of tbe globe, to which the
English herbs called Plantain belong, some of which have been introduced with seed into New Zealand. (Name
so applied by the Romans.)
§ a. Scape one-, orfeic- {two- to six-) flowered.
1. Plantago uniflora, Hook, fil.; pusiUa, foliis petiolatis lineari-lanceolatis sinuato-dentatis integerri-
inisve basi lanatis, scapo gracili pubeseente 1 -floro, bractea parva late ovata obtusa, sepalis liuearibus
obtusis.
H a b . Northern Island. Top of the Ruahine mountains, Colenso.
Stem very short, stout. Leaves few, g-1 inch long, petiolate, linear-lanceolate, sinuate-toothed or entire,
villous at tlie base. Scape longer than the leaves, pubernlous, one-flowered. Flower smaU. Bract very short,
blunt. Sepals narrow, hnear.—I have but three imperfect specimens of this curious little plant, which is very nearly
allied to the P. carnosa, but the sepals are narrower.
2. Plantago carnosa, Br. ; glaberrima v. pilosa, radice crassa, foliis plurimis steUatim patentibus
lanceolatis integerrimis inciso-lobatis dentatisve carnosis basi nudis v. villosis, scapis brevibus erectis
