The images below are first P. bullata var bullata, followed by P. bullata var bracteata, followed by P. bullata var forrestii. In 2014, P. Eveleigh, J. Nielsen and D.W.H. Rankin studied the Bullatae Section with the result that P. bracteata and P. forrestii are combined as varieties of P. bullata. Reasoning behind this is explained in the Reference Paper listed above. This species is distinguished by being long-lived, subshrubby, forming branched woody stems covered with the dried leaves of previous years near the apex and leaf scars below. The leaves are bullate, rugose, vary in size and in winter are smaller with short or no petiole, and with farina underneath and in summer larger with a longer petiole and no farina. Flowers are yellow. See also a blog post on this.
