Gen. I. SUTTONIA, A. Rich.
Flores polygamo-dioici. Calyx 2-5-partitus, rarius obsoletus. Peíala 4 -5 , rarius basi connata.
Stamina 5 ; filamentis brevibus, basi corollæ insertis ; antheris basi cordatis. Ovarium ovatum, in stylum
breve attenuatum, 1 -loculare, 1 - rarius 2-ovulatum ; ovulis placenta globosa immersis ; stigmate cyatliiformi,
lobato V. lacero. Fructus subbaccatus; putamine crustáceo, 1 - rarius 2-spermo. Semina reliquiis membranaceis
placentæ induta.
Shrubs or small trees, quite glabrous, with scattered, alternate, exstipulate, entire or sinuated leaves, and very
inconspicuous axillary, solitary, or fascicled flowers. All parts covered with glandular oil-cavities, seen as transparent
dots ■when the leaves are dried and held between the eye and the light. The species are confined to New
Zealand, Lord Auckland’s Group, Campbell’s Island, and Norfolk Island. Flowers monoecious, rarely liermaphi-odite.
Calyx of two to five lobes, sometimes wanting. Corolla of five concave ciliated petals, sometimes uuited at the
base, often becoming reflexed before falling away. Stamens short, inserted on the petals, 'with short broad filaments
and subsagittate anthers broad at the base. Ovary somewhat fiaggon-shaped, turgid below, tapering into a
short thick style, which is terminated by a broad-lobed concave or fimbriated stigma, one-celled. Ovules one,
rai-ely two, immersed in a globose fleshy placenta, which so much resembles a seed that it requires careful examination
to find the ovules in it. In the ripe fruit this fleshy placenta appears as a thin, brown, membranous covering
to the rounded seed, which has a very delicate testa, horny albumen, and terete rather curved radicle lying across
the seed. (Named in honour of the Rev. Br. Sutton, F.L.S., author of a paper on British species of Orohanche)

A small erect tree, leafy at the ends of the branches, everywhere perfectly glabrous. Leaves spreading, 4 - 7
inches long, about 1 broad, linear, blunt, quite entire, narrowed into a short petiole, marked with copious small
oblong transparent glands, seen in the dried leaf between the eye and the light. Flotcers very numerous, in many-
flowered bunches, growing from buds on the branchlets, below the leafy portion. Peduncles 4-4 inch long, without
bracts, stout, straight. Calyx of flve blunt cihate lobes. Petals five, linear-oblong, blunt, revolute, ciliated. Ovary
with a short style, large cup-shaped irregularly lobed stigma, and one or two ovules. Berry 4 inch long, oblong

A small leafy tree, very closely resembling Pittosporum undulatum in appearance. Bark dark, of the branchlets
red-brown. Leaves 1-14 inch long, obovate, blunt, on short petioles, waved, reticulated on both sides, studded
with little round glands. Flowers fascicled, sessile, very small. Calyx two- to four-lobed or none. Petals revo-
Inte; anthers as large as or larger than the petals. Ovary with a sessile capitate stigma. Berries clustered, on short
pedicels, 4 inch long, oblong.

Very similar to a shrubby Coprosma in habit and appearance. Branches flexuose, tortuous, woody. Leaves
scattered, alternate, or fasciculate on abbreviated lateral shoots, 4- I inch long, coriaceous, broadly obovate, blunt,
retuse or obcordate and bilobed, marked -with rounded glandular dots, finely reticulated, quite entire. Flowers very
minute, scattered in little bunches. Calyx four- to five-lobed. Fetals four or five, obovate. Opaiy with a short
style and broad concave irregularly-cut stigma. Berry depressed, spherical, one-seeded.—This species has a very-
wide range in latitude, being frequent from the Bay of Islands to Lord Auckland’s Group and Campbell’s Island,
where the leaves of seedling plants are irregularly serrate or lobed. I have not ventured to make a different species
of var. jS montana, though Mr. Colenso considers it as such. I have no good flowers or fruit of i t ; wbat there are
do not differ from those of M. divaricata, and the very variable nature of the leaves is equally conspicuous in both
plants. The leaves of the var. /3 are however longer, more obovate, rounded, seldom retuse, and the plant forms
a small tree: hence, though Sir. Colenso’s specimens are insufficient for description as such, I suspect them to
r to a new species, for which the name S. montana may be retained.
4. Suttonia nummularia, Hook. fil.; fruticulus prostratus, caulibus gracilibus elongatis parce ramosis,
foliis parvis breve petiolatis rotundatis reticulatim venosis, floribus sparsis sessilibus soHtariis axillaribus
ramulisque nudis, calyce brevi 4-lobo, petalis obovato-rotundatis longe ciliatis, bacca subglobosa.

ILvb. Nortliern Island. Top of Euahine range. Lake Eotoatara, etc., Colenso.
A very small, prostrate, alpine species. Stems slender, a span to a foot long, sparingly branched, rooting at
the base; branches scarred, ascending. Leaves small, uniform, spreading, coriaeeous, shortly petiolate, orbicular;
margins quite entire, recurved, much wrinkled :vith reticulated veins, and dotted with rounded glands. Flotcers
scattered, solitary, axillaiy or growing fi-om the branches, very minute. Calyx very small, four-lobed. Petals
four, concave, ciliated. Stamens large for the size of the plant, sessile on the petals. Berry round, the size of a
peppercorn.—P late XLV.
