Leaves bullate, dark green with a purple midrib, farinose when young (centre of rosette in spring), oblanceolate at flowering with an insensible, broadly winged petiole, becoming ovate with a marked narrow purple petiole in summer, 5-16cm long by 2-6cm across, irregularly toothed. Flowers pinkish-lilac with a white-edged yellow eye,2.5-3cm across, farinose, apparently borne basally at first, but in fruit in umbels of four to many on a stem at first no more than 2cm and hidden within the leaves, but extending to 10cm when it sometimes develops foliaceous bracts on rootable stem-buds if fruit is set. Resembles a giant version of P. gracilipes but develops a stem when fruiting. Early spring. East Nepal to Arunachal Pradesh, in damp ground by streams, often in light woodland at 2200-3600m. Grow in fertile, humid sites in full shade, cool in summer and avoiding the worst frosts.
