184 FLORA OF NEW ZEALAND. [ Convolvulacec. 
rotundato integris v. sinuato-lobatis apice rotundatis acutisve, pedunculis teretiusculis, bracteis cordatis 
obtusis acutisve calyce sequilongis, capsulis magnis globosis, seminibus grossis atris. Br. Prodr. p. 483 in

Has. Abundant on the shores of all the Islands, Banks and Solander, ete. (A native of Britain.) 
This plant I have carefully compared with the European C. Soldanella, and with Mr. Brown’s C. reniformis 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 C. tuguriorum, the capsule being large, nearly 3 
inch broad, globose, with a stiff point, and containing 1-3 black seeds, nearly 4 inch broad. In other respects, 
however, these plants are very similar, and only to be distinguished by the prevailing succulent habit of this, its 
broader, kidney-shaped, blunter leaves, with rounder deeper sinus, and very rosy flowers. 
4. Oalystegia marginata, Br.; scandens, foliis late sagittatis oblongo-linearibus acuminatis sinu lato 
lobis divaricatis elongatis integris sinuatis bidentatisve, pedunculo petiolo breviore angulato angulis margi- 
natis subalatis undulatis, floribus parvis, bracteis corolla brevioribus v. longioribus. Br. Prodr. Tas.

Has. Northern Island. East coast, Banks and Solander, Colenso. 
A remarkably distinct little species, slender, climbing. Petioles 1-2 inches long. Leaves longer than the pe- 
tioles, sagittate, linear-oblong, or ovate, acuminate, sinus broad, lobes at the base spreading, long, entire or un- 
equally two-lobed or toothed. Peduncles shorter than the petioles, with crisped wings. Flowers 3-1 inch long, 
white. Corolla small, hidden by the bracts, or exserted. This species was discovered by Mr. Brown in the Port 
Jackson district of Australia. —PLATE XLVIII. Fig. 1, bracts and calyx; 2, corolla laid open; 3, ovarium :—all

Calyx 5-partitus, nudus. Corolla campanulata v. infundibuliformis, 5-plicata. Ovarium 2—9-loculare; 
loculis 2-spermis. Stylus indivisus; stigma capitatum, 2—3-lobum. Capsula 2-3-locularis. Br. Prodr. 
Climbing 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; the various 
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 Linneus 
from up, which he erroneously supposed to mean a Convolvulus (but which signifies a worm), and õpotos, like.) 
1. Ipomea pendula, Br.; glabra, foliis guinato-digitatis, foliolis lanceolatis mucronulatis margine 
integerrimis extimis indivisis bifidisve, pedunculis 1-3-floris, calycis foliolis obtusis tubo corolla multoties 
brevioribus. Br. Prodr. p. 486. Andrews, Bot. Rep. t. 613. A. Cunn. Prodr. Convolvulus mucronatus, 
Forst. Prodr. 
Haz. Northern Island. East coast, Banks and Solander. Cavallos Islands, Colenso. Bay of Islands, 
Cunningham, ete. (Cultivated in England.) 
A climbing herb, with five-foliolate leaves. Leaflets lanceolate, acuminate, guite entire, the two outer some- 
times bifid. Peduncles one- to three-flowered; flowers pendulous. Calyz lobes blunt, much shorter than the tube 
of the corolla, which is pink, about 14 inch long.—Found also in Australia.
