scarcely longer than the calyx to twice as long. Sepals rarely above 3 lines 
long. Corolla about fin. long. Ovary very imperfectly 2-celled. Stigmatic

Hub.: Brisbane River. Moreton Bay, F. v. Mueller ; common in southern localities. 
The species is also in Norfolk Island and in New Zealand Some specimens have the aspect 
of some varieties of Convolvulus erubescent, but are at once distinguished by the large bracts. —

2. C. sepium (found in hedges), /<’. Hr. Prod. 483. A tall rather slender 
herbaceous twiner, quite glabrous or very slightly pubescent, with a creeping 
perennial rootstock. Leaves from broadly ovate-triangular to lanceolate-hastate, 
acutely acuminate, cordate with angular basal auricles or lobes, mostly 2 to 4in. 
long but sometimes larger. Peduncles longer than the petioles and often as 
long as the leaves, bearing a single large flower of a pure white or more or less 
tinged with pink. Bracts large, ovate or ovate-lanceolote, leafy, acute or scarcely 
obtuse, longer than the calyx and enclosing it. Sepals ovate-lanceolate or 
lanceolate-acuminate, rather unequal, 4 to 5 lines long. Corolla 2 to 3in. long. 
Ovary incompletely 2-celled, surrounded by a cup-shaped disk. Stigmatic lobes 
ovate or oblong, obtuse. Capsule 1-celled. — -Calystegia sepium, Chois, in DC.

Bab.: Southern coast (rare). 
The species is abundant in the temperate and subtropical regions of the northern hemisphere, 
and is also in New Zealand. When on tbe seaeoast the lower leaves are sometimes thicker, 
shorter, and more obtuse, but appear to me to be always very different from those of Convolvulus 
Solclanella . — Benth. 
3. C. Soldanella (resembling a Soldanella), R. Br. Prod. 483, A glabrous 
perennial with a creeping rootstock and prostrate trailing or shortly twining 
stems. Leaves on rather long petioles, broadly rounded-cordate or kidney- 
shaped, entire or angular-lobed, rather thick, mostly about lin. but sometimes 
2in. diameter. Peduncles 1- flowered, about as long as the leaves. Bracts 
broadly ovate-cordate, very obtuse, rather shorter than the calyx. Sepals nearly 
fin. long, broad and thin, all very obtuse or the inner ones almost acute. 
Corolla pink or purplish, rather smaller than in C. sepium. Ovary incompletely 
2-celled, surrounded by a cup-shaped disk. Stigmatic lobes ovate or oblong, 
usually narrower than in C. sepium, much shorter and broader than in C. 
erubescens. Capsule 1-celled. — Calystegia Soldanella, Chois, in DC. Prod. ix.

Hab.: Little Burleigh Head, J. Shirley ; Fraser’s Island, Hon. Miss Lovell. 
The species is common on the extratropical seacoasts in both the northern ai d southern 
hemispheres both of the New and the Old World, including New Zealand, where it varies much 
more than in the northern hemisphere. 
7. CONVOLVULUS, Linn. 
(Most kinds having an interesting habit.) 
(Jacquemontia, Chois.) 
Corolla campanulate, entire, angular or rarely lobed. Ovary 2-celled, with 
2 ovules in each cell. Style filiform, with 2 ovate oblong linear or subulate 
stigmatic lobes. Fruit a dry capsule, completely or sometimes incompletely 
2-celled. — Twining prostrate creeping or erect herbs, or in species not Australian
