Taxonomic notes: Most of the specimens from S.Aust. must be identified as belonging to the subspecies tenuiflorum but others disagree in that they have a distinct basal rosette and/or corolla lodes less than 4 mm long (cf. K. Jakobsen in P. Davis (1978) Fl. Turkey 6:181). However, none of these specimens have the distinctly notched petal apex of subsp. acutiflorum, the second subspecies generally recognised. C. tenuiflorum has often been confused with C. pulchellum (Sw.)Druce which is mainly distinguished by its pedicellate flowers. Eichler (1965) also mentions C. littorale (Turner)Gilmour in connection with the pink-flowered species. Its occurrence in S.Aust. could not be confirmed. C. tenuiflorum is usually easily distinguished from C. spicatum by its few-flowered monochasia, if monochasia are at all present. As the latter branching pattern is usually associated with an atypical spreading habit and many of the lower flowers do not produce fully developed seeds it is thought that these specimens may represent hybrids between the two species.
