276 FLORA OF TASMANIA. [Convolvulacea. 
Leaves petiolatc, varying from narrow-linear to broadly oblong-cordate, and from quite entire to hastate, and deeply 
five- to seven-lobed or -partite, with long or short, narrow or broad segments. Flowers solitary, axillary, generally 
pink, very variable in size. Pedicel with two small bracts. Sepals orbicular. Corolla i-l inch across. — I have in 
the New Zealand Flora alluded to the probable identity of this with some European forms of Convolvulus, as first 
suggested by Brown (Prodr. I. c), who remarks that his angustissimus is perhaps not distinct from erubt y< •>. \\ hich 
is itself too nearly allied to the European C. althceoides and lanuginosa. That C. angustissimus is the same with C. 
erubescens there can be no doubt, for many of our specimens have the leaves of both forms on one plant ; and after 
a careful comparison with numerous suites of specimens of C. altliaoides, I can find no character whereby to separate 
the Australian plant from it, except its usually broader and shorter sepals. There is also a South American plant, 
common (under several names) from Mexico to Chili, which will probably prove the same.

There are four species of this genus in Australia, of which two are the Tasmanian ones here described, and 
the others are both natives of New Zealand also. The genus entirely resembles Convolvulus in habit and general 
appearance, but has the calyx hidden between two large, foliaceous bracts, the stigmata broader and blunt, the ovary 
incompletely bilocular, and the capsule unilocular. (Name, KaXvi, a calyx, and oreyos, a covering.) 
1. Calystegia Sepium (Br. Prodr. 483); volubilis, caule glaberrimo v. puberulo, foliis oblongo- 
sagittatis acuminatis alte cordato-bilobis, lobis rotundatis angustatis lobatis truncatisve, bracteis obtusis 
acutisve, pedunculis anguiatis plerumque petiolo duplo longioribus.— Clioisy in DC. Prodr. ix. 433 j Fl.

Hab. Abundant in several parts of the Island, climbing over bushes in shaded places.— (El. Dec.) 
Distrib. South-eastern and South-western Australia; New Zealand; St. Paul's Island (South Indian 
Ocean) ; Chili, Java, temperate Europe, North America, and Asia. 
A very beautiful plant, as common in some parts of Tasmania as in England, where it is known as the Greater 
Bindweed, Bearbind, or Hedge-Lily. It may be recognized by its twining habit, targe, oblong-aagittate, acuminate 
leaves, with deeply bilobed, cordate bases, and angled lobes, and its large, white or rose-coloured flowers. The root 
(rhizome?) is sometimes large and tuberous, considered poisonous in Europe, but eaten by the New Zealanders.
