“…Apteranthes joannis Maire from Morocco is closely related to A. europaea , but was not included in this study because of its undisputed status as a good species (cf. also Gilbert, 1990; Raynaud, 1991). Vegetatively and florally similar to A. europaea , the stout, papillose and rugose corolla of A. joannis characterizes this invariable species sufficiently (cf.…”

“…Raynaud (1986) recognized the subspecies maroccana against the typical subspecies in Morocco on the basis of ostensible differences in the structure of the interstaminal corona. In the last complete review of the genus Caralluma (which included all Apteranthus species), Gilbert (1990) lumped all taxa of the A. europaea complex into one variable species without discussion.…”

The Apteranthes europaea complex (Apocynaceae-Asclepiadoideae-Ceropegieae-Stapeliinae) distributed from Morocco/southern Spain along the North African coast of the Mediterranean Sea up to Sinai, Negev and southern Jordan is studied with emphasis on stem and flower morphology by SEM, chromosome sizes and flavonoid compounds. Apteranthes europaea was found to be rich in rather uncommon flavone glycosides. Of these, luteolin 4 ′ -neohesperidoside represents the major flavonoid of all samples; luteolin-are reported here for the first time. Flavonol glycosides also occur, but in much smaller quantities. The different flower morphs, variation in stem and corolla epidermal structures, slight variations in the length of the 2 n = 22 chromosomes and in quantitative flavonoid composition are taxonomically best reflected by subdividing the complex into a western var. europaea (Europe and Africa) and an eastern var. judaica (Sinai, Arabia).

“…Gilbert (1990) suggested that it is 'a relict with no close affinities to existing species or even genera' and that it deserves to be placed in a monotypic genus. f. As pointed out by Gilbert (1990), this hypothesis would explain many of its unusual features but it utterly fails to explain the fact that a taxon very similar to C dodsoniana has recently been found in Oman, southern Arabia, where Pseudolithos is not known to occur. f.

“…This could be taken to indicate that the two groups such as round and acute angle varieties merit formal recognition at least as subspecies. The status of the varieties within C. adscendens seems more questionable as Gravely and Mayuranathan indicated that intermediates are apparently common (Gilbert 1990). The present accounts indicate that C. adscendens var.…”
