 section Omphalodes. Hairs of the plant usually longer and looser than in 

 C. austrah^ the pedicels often rather longer and occasionally a few bracts de- 

 veloped at the base of the raceme, the foliage, inflorescence, and flowers other- 

 wise the same. Nuts depressed, spreading, abnost orbicular, with a nnich- 

 raised membranous shortly fringed border, the enclosed upper concave suvfnce 

 quite smooth or rarely with a slightly raised midrib bearing a few hooked 

 prickles, the under surface convex and quite smooth, the attachment as m

Order LXXXI. CONVOLVULACE^. 



Plowers regular. Calyx free, persistent, of 5 distinct much imbrif^atcd 

 sei)als, rarely united in a 5-toothed or 5-lobed caljx. Corolla campanulate 

 or funnel-shaped or rarely rotate or with a cylindrical-tube, the limb usunllv 

 spreading, 5-angled or 5-lobed, folded in the bud or very rarely imbricate. 

 Stamens 5, inserted in the tube, alternate with the lobes or angles of tlie 

 corolla, often of unequal lenoth ; anthers versatile or almost erect, with 3 

 parallel cells opening by longitudinal slits. Ovary free, 2-^ 3- or 4-celled, 

 rarely divided into 2 or 4 distinct carpels, with 1 or 2 erect or ascending 

 ovules in each cell or carpel or l-celled with 2 or 4 ovules; style single or 

 more or less divided into 2 entire or 2-fid branches or styles. Fruit either 

 a capsule opening in 3, 3, or 4 or twice as many valves, leaving the dissepi- 

 ments attached to the axis, or opening transversely, or bursting irregularly, 

 or succulent and indeluscent. Seeds with a smairqu^^ntity of mucilaginous 

 albumen or without any ; cotyledons usually very much folded; rarely strnight 

 or imperceptible.— Herbs often twining or rarely shrubs, woody twiners or 

 even trees, or (in Cuscuta) leafless, twining parasites. Leaves alternate. 

 Inflorescence various, usually axillary and more or less cymose or peduncle^ 

 1-flowered. Bracts and bracteoles usually small or deciduous, rarely large 

 and persistent. Flowers often large and showy, rarely very small.
