The bulbs of the Cyrtanthus genus are called "fire-lilies" for being the first plants to flower after a fire. The rhizomes of the Arum lily (Z. aethiopica) is of such culinary delight to the porcupine that a limited display of flowering Arum lilies is an indicator for a thriving porcupine population. The Lanaria lanata is a very common plant which can be seen in almost obscene abundance after fire on lower slopes. The Ornithogalum thyrsoides is very common on the flats. This "chincherinchee" is extremely poisonous for livestock and farmers are in the habit of pulling them out.
