Flowers blue. Bracts none ... ... ... ••• 3. C. australe. 



1 C. LATiroLiUM, R. Bi-. A straggling perennial, obscurely scabrous. Lower- 

 leaves, ovate, stalked, 1-2 inches long ; stem-leaves smaller, narrower, and sessile. 

 Flowers on slender stalks, forming a terminal, elongated, one-sided raceme or 

 scorpioid cyme. Calyx-segments about 1 line long, rather broad. Corolla rather 

 small, usually blue. 



Circular Head ; also in New South Wales, Victoria, and Queensland. Fl. 

 spring and summer. 



2. C. SUAVEOLBNS, M. Br. Sub-erect, branching from a perennial stock, 

 mostly 6-18 inches high. Leaves broadly or narrowly lanceolate, the lower ones 

 stalked, and often 2-4 inches long ; stem-leaves smaller and sessile, like all the 

 green portions of the plant coarsely hairy. Inflorescence as in the last, but 

 often branched. Each flower-stalk subtended by a bract. Calyx-segments 

 ovate, lanceolate, about li line long, less hairy than in C. australe. Corolla 

 white or yellowish. 



Very common; also in New South- Wales, Victoria, South Australia, and 

 Queensland. Fl. Nov.-Jan. 



3. C. AUSTRALE, R. Br. Sub-erect and branched from a perennial stock, often 

 2 feet high, more or less coarsely hispid. Leaves broadly or narrowly lanceolate, 

 lower ones stalked, often 4 inches long ; stem-leaves smaller and sessile. 

 Inflorescence similar to the last, but more elongated and branched, and without 

 subtending bracts to the flowers. Calyx-sefrments also smaller, broader, lesa 

 deeply divided, and more hirsute. Corolla blue or rarely white. 



Common in dry or sandy places ; also in New South Wales, Victoria, South 

 Australia, and Queensland. Fl. Oct.-Dec. 



3. LITHOSPERMUM. 



Calyx divided nearly to the base. Corolla-tube cylindrical, without scales 

 at orifice ; lobes short, spreading. Stamens included. Nuts 4, hard and stony. 



A common genus in the Northern Hemisphere. Represented in Tasmania by 

 a widely-spread introduced species. 



L. ABVBNSE, Linn. An erect annual, more or less hairy. Leaves lanceolate,, 

 lower ones stalked, broad, obscurely toothed, 1-2 inches long ; stem-leaves 

 narrow, sessile. Flowers numerous, sessile, solitary in the axils. Calyx-segments 

 linear, 2-3 lines long in the flower, enlarging to \ inch subsequently. Corolla 

 white, the tube about as long as the calyx. Nuts about 2 lines long, stony, 

 pitted, and tuberculate. Fl. all spring and summer. 



Oedee lAll.—CONVOLVULACEJE. 



Flowers regular. Calyx free from ovary. Sepals 5, usually free, rarely united* 

 Corolla usually funnel-shaped, sometimes campanulate or tubular, with spreading 

 lobes. Stamens 5, inserted in the corolla-tube. Ovary 2, 3, or 4-celled, or a 

 similar number of partially-distinct carpels. Rarely dissepiment absent, and 

 consequently 1-celled. Ovules 1 or 2 in each cell. Style single. Stigmatic 

 branches 2, simple or bifid. Fruit capsular or succulent. 



A very large order, found almost throughout the world. 



Plant trailing or twining. Flowers funnel-shaped,
