H a b . Abundant ou the shores of all the Islands, Banhs and Solander, etc. (A native of Britain.)
This plant I have carefully compared with the European 0. Solda,udla. and with Mr. Brown’s 0. reuifornik of
Port Jackson and Tasmania, both of which seem one species, and that a very common one on the shores of various
parts of the world. In fruit it is very easily distinguished from O. tuguriorum, the capsule being large, nearly i
mch broad, globose, with a stiff point, and containing 1-8 black seeds, nearly | inch broad. In other respects
however, these plants are very similar, and only to be distinguished by the prevailing succulent habit of this, ite
broader, kidney-shaped, blunter leaves, with rounder deeper sinus, and very rosy flowers.

^ Climbmg herbs (rarely erect), chiefly differing from Calystegia in wanting the bracts below the calyx, and in
having a simple lobed stigma. The species are very numerous indeed, and almost wholly tropical; tlie’varions
kinds of Batatas and Sweet Potato belong to it ; of these the “ Kumerahoa” was found cultivated by Banks and
Solander in these islands, as all over the Pacific, It is not known where it is a native. (Name derived by Linnæus
from ok, which he eironeously supposed to mean a Convolvulus (but wliich signifies a worm), and dpoios, like)

A climbing herb, with five-foliolatc leaves. Leaflets lanceolate, acummate, quite entire, the two outer sometimes
bifid. Peduncles one- to three-flowered ; flowers pendulous. Calyx lobes blunt, much shorter than the tube
of the corolla, which is pink, about 1^ inch long.—Found also in Australia.

The absence of the two large bracts which include the calyx of Calystegia distinguishes the New Zealand Con-
volvulas. The species of this genus are numerous, and found in all latitudes, except the Arctic and Antarctic ;
several are fonnd in Australia and Tasmania. (Name from con and volvo, to twine together)

H a b . Northern and Middle Islands. Bay of Islands ? Cunningham. Canterbury, (Cultivated
in England.)
I have very indifferent specimens of this plant from Dr. Lyall, and presume it to be that alluded to in
Cunningham’s ‘ Prodromus’ as C. arvensis ? found at the Bay of Islands. So common an Australian plant is very
likely to be a native of New Zealand, especially as it is further very probably identical with the most widely diffused
English, European, and Asiatic C. arvensis, and the same as a South African species that has been published under
several names. Mr. Brown says of C. eruhescens, “ Too closely allied to C. althæoides and C. lanuginosus,” both of
them European species ; and neither his description of C. eruhescens nor of C. angustissimus (of which he says,
“ præcedenti affiuis, an distincta ?” ) includes nearly all the varieties we now know of C. eruhescens. This is a point I
shall discuss in the Tasmanian Flora.—A twining or prostrate, slightly hairy or pubescent plant, with stems 4-1Ü
inches long. Leaves oblong or hastate, sometimes linear, entire or three-parted, the lobes very variable in
length and breadth. Peduncles one- to three-flowered, bracteolate. Calyx lobes oblong, blunt or mucronate.
Corolla generally rose-coloured, g—1 inch across.

A small, silky, procumbent herb, variable in size, abundant in Australia, Tasmania, and various warm countries
of South America, etc. Stems slender, 3-10 inches long, sometimes tufted, creeping. Leaves solitary j petioles
erect ; blade kidney-shaped, quite entire, rounded or notched at the point, more or less silky on both sides, g—1
incli broad. Feduncles solitary, axillary, about as long as the petioles, without bracts. Flowers small, yellow.
Calyx five-partite. Corolla nearly rotate, having a short tube and flat five-lobed limb. Ovaries two, each cell with
two seeds and one style ; stigmas capitate. Capsules membranous, indéhiscent, one-seeded. (Name from 8is,
double, and xov8pos, a seed)

A very remarkable genus of parasitical, climbing, leafless plants, that germinate in the ground, from a slender
spiral undivided embryo, but whose climbing stems become detached from the root, and derive their nourishment
from little suckers, that penetrate the bark, and come into contact with the wood of the plants they grow upon.
