Morphology Reproductive morphology Flowers Calyx
Calyx 1.5–2.5 mm long
Morphology Reproductive morphology Flowers Corolla

N1–3; C1, 2
Ecology
Altitude range c. 150–900 m.
Vernacular

Note
The type of A. paradoxa Chiov. represents a shrubby form, up to about 0.6 m tall, with 1–3 pairs of pinnae, and very reduced, up to c. 5 mm long, ± sessile, few-flowered inflorescences, perhaps with purplish filaments. Populations of this form occur in C1 and C2 on limestone and gypsum at 150–360 m altitude. Typical A. hamulosa also occurs in the same general area and in the field the two indeed give the impression of being distinct species. Mr J. B. Gillett has suggested “ A. brevis ” as a new name for this entity, but this has not been published. However, there is also a considerable variation within “ A. brevis ”.
