Calystegia sepium is a widespread and highly polymorphic species with a number of subspecies recognized. Brummitt (1967) studied the S.A. specimens of C. sepium and concluded they belong to C. sepium subsp. roseata Brummitt. However based on his key to Calystegia in Flora Europaea (Brummitt 1972), the pale pink, occasionally white, flowers, rather than bright pink, ± glabrous foliage and often shortly acute leaf apex, suggest they are better placed in C. sepium subsp. sepium.

There is a scattering of material from the SE region towards the Vic. border with smooth seeds (characteristic of subsp. fililobus), but leaf morphology (and sometimes sepal indumentum) intermediate with subsp. peninsularum. Two specimens from the Mt Lofty Ranges were annotated by Johnson in 2001 as having leaf morphology matching subsp. fililobus, but with reticulate (not smooth) sculpturing of the seeds. The distinctive typical subsp peninsularum with obvious spreading basal lobes is largely confined to southern EP and YP.

Lower cauline leaves deeply lobed at base, basal pair of lobes linear to obovate, lateral to recurved, often with a recurved secondary lobe from the lower margin, ascending and terminal lobes distinct, linear; upper leaves with very narrow lobes, terminal lobe < 1.5 mm wide. Pedicels 3–8 mm long; outer sepals moderately to sparsely hairy with appressed, ascending to spreading hairs; corolla 8–13 mm long. Seed surface with sparse low reticulate ridges.

S.A.: FR, EA, EP, NL, MU, YP, SL, KI, SE. Grows on seashores and coastal cliffs and extends inland, mainly in heathlands and grasslands. Flowers: Nov.–Feb.

This subspecies includes distinctive variants which occur in coastal areas mainly in the southern parts of the Yorke and Eyre Peninsulas. Without complete material it is difficult to distinguish from smaller flowered forms of C. angustissimus subsp. angustissimus which occur to the north. Some plants from the Mt Lofty Ranges are similar to C. angustissimus subsp. fililobus in leaf morphology, but have sculptured, rather than smooth seeds. The S.A. subspecies of C. angustissimus need to be re-evaluated, based on a detailed study of the geographical variation in seed size and sculpturing, as well as the highly plastic leaf morphology.

Parasitic on species of Wilsonia (Convolvulacae), Selliera (Goodeniaceae) and Chenopodiaceae. C. tasmanica var. brevistyla Yuncker, Mem. Torrey Bot. Club 18: 143 (1932), has been recorded from 2.5 km south of Martin Washpool Conservation Park (SE). It differs from the type variety in having much shorter styles though the true biological significance of this variety is in doubt. It can be distinguished in having styles < 0.5 mm long compared with > 1 mm for the type variety.
