The plant here figured belongs to the section Hoarea DC., a group of species characterised by the presence of a tuber (of hypocotyl origin) and radical leaves, and by the absence of a perennial aerial stem. This section comprises approxi- mately 50 species which are native mainly to the south- western part of the Cape Province. One of the most striking features of P. Andrewsii is the great diversity in the shape of the leaves found on one and the same individual. As this species is a deciduous geophytic perennial a new crown of leaves is formed each season. The outer lowermost leaves are usually entire and only rarely show the presence of lobing, whereas the inner leaves are usually pinnately or even bipinnately lobed. The bracts subtending the branches of the scape likewise exhibit hetero- phylly, and as the latter character is frequently met with in species belonging to the above-mentioned section, the degree of lobing of the leaves is of relatively little value as a basis for classifying them. In the very broad sense of Knuth in his monograph of the Geraniaceae (1.c.), our plant would be considered as belonging to P. longifolium (Burm. f.) Jacq., which is an aggregate species consisting of no less than six varieties. A study of the synonyms under each of these varieties, and especially.
