This very attractive small species from southern Greece is hard to distinguish from A. pallida and A. lutea by its flowers and general appearance.

In fact, many specimens show intermediate features between pallida and lutea so hybridization might play a role in this taxon, too.

The tuberous underground stem represents the only reliable characteristic which is very elongated in this species in contrast to globose or ovoid tubers of A. pallida and lutea.

 

Although susceptible to moisture and constant substrate humidity this species has proved to be quite frost tolerant if kept completely dry and isolated properly.
