Notes
Subsp. pes-caprae, with more deeply bilobed leaves, has not been recorded from Africa. Prof. H. St. John pointed out to me after examining the material in the East African Herbarium that both subsp. pes-caprae and subsp. brasiliensis occurred in Arabia. It is therefore of interest to see to which subsp. the type of Forskål’s I. biloba belongs. The type material is in my opinion rather too poor for a firm decision, but it is probable that it belongs to subsp. brasiliensis and not to subsp. pes-caprae as previously thought.
