Morphological variation within H. krichauffianus sens. lat.

Specimens of Hibiscus krichauffianus were sorted into four morphotypes. A representative specimen of each is shown in Fig. 2, seeds in Fig. 3 and typical habitats of morphotypes A – C in Fig. 4. The morphotype encompassing the largest number of specimens, including those from NT and Vic., and many from SA, Qld and NSW was assigned morphotype A ( Fig. 2 a, 3 a, 4 a). The morphotype encompassing the second largest number of specimens, all from eastern Qld , was assigned morphotype B ( Fig. 2 b, 3 b, 4 b). Specimens from the Nullarbor region of WA and SA, along with those collected as far east as near Wilcannia in western NSW were assigned morphotype C ( Fig. 2 c, 3 c, 4 c). Specimens from the Murchison region in WA, of which only four were available for study (there were five specimens in total in herbaria), were assigned morphotype D ( Fig. 2 d, 3 d). Features distinguishing the morphotypes are summarised in Table 1 and the distribution of each morphotype is shown in Fig. 1 .
