P. muscoides is an extremely tiny high-altitude species. The homostylous flowers are pale violet with a white tube or pure white. Leaves are sessile, efarinose and broad at the apex with 3-7 acute lobes. See related P. tenuiloba which is larger flowered and with lobes longer, very narrow and cleft into two linear spreading lobes. The last image shows the relative sizes of the flowers of the two species.
