Biology: P. gaudichaudii is characterised by its long narrow leaves (20-40 times longer than broad) and they are usually glabrous, or if pubescent then with hairs of mainly equal length particularly on the lower leaf surface. Intergrades into P. varia sometimes occur but they have usually shorter leaves (5-8 cm long) and often have been recorded together with some plants of P. gaudichaudii.
