5. C. triangulare, R. Br. Prod  . 407. Stems weak procumbent or stragging, extending sometimes to 2 ft. or more, the whole plant green or with but little of white meal on the young shoots. Leaves on rather long petioles, from ovate to oblong or to broadly hastate in the typical form, obtuse or shortly mucronate, under 1 inch long, the upper ones often and sometimes all lanceolate. Flowers very small, in clusters or little cymes in a terminal interrupted spike or along; the short distant branches of a slender terminal panicle, or the lower ones in the axils of the upper leaves. Perianth-segments broad and concave, sometimes closing over and covering the fruit, sometimes smaller and much contracted at the base. Stamen usually 1. Styles short. Seed flat, horizontal, about ½ line diameter, in a very thin membranous Pericarp.

- C. trigonon, Roem . and Schult.  Syst. vi. 275; Moq. in DC Prod. xiii. ii. 65. Queensland. Armadilla , Barton. 

N. S. Wales. Paramatta , Woolls ;  Namoi river , Leichhardt;  New England, C. Stuart.  The habit is nearly that of Rhagodia hastata  , but the fruit is never succulent, and the inflorescence rather different. The C. triangulare  of Forskähl being reduced by Moquin to C. murale  , there seems no reason to suppress Brown's name of C. triangulare  for the present species.

Var. stellulatum. Perianth-segments with a rather small concave lamina contracted at the base into a linear stipes (reduced to the somewhat prominent midrib). Leaves of the typical form. - New England, C. Stuart. 

Var. angustifolium. Leaves linear-lanceolate or the lower ones lanceolate-hastate. Perianth of the typical form. - To this belong the Queensland specimens and some from New England.
