Notes
Since the species is cosmopolitan and also much cultivated, the literature is vast and hundreds of illustrations have been published (see Index Londinensis for earlier ones). The division of the pinnules is very variable and there are numerous cultivars some of which may have been grown in East Africa. The name var. kenyense refers to specimens with the pinnules deeply divided into narrow divisions. Faden & Evans 69/914! (Kenya, Thika, behind the Blue Posts Hotel, under Chania Falls, 3 Aug. 1969) has rounded obovate-transversely elliptic undivided or very slightly incised pinnules ± 0.8×1 cm and Greenway 9123! (Tanzania, Masai District, Olmoti, 6 Dec. 1956) from a limestone cave at 3000 m is rather similar; both are probably only environmental forms of A. capillus-veneris .
