Lotus creticus

Lotus creticus is a species of perennial herb of the family Fabaceae found in tropical Africa. It is symbiosis-competent and engages in nitrogen-fixing symbiotic interactions with species of the Ensifer genus[3][3]. It comprises three varieties found in the Mediterranean. There is some controversy as to whether each subgroup could be considered the same species but are classically described as being subgroups. Varieties consist of the most commonly cited silky-hairy var. creticus, which is widely distributed in its western part of the coast; the non-silky var. glabrescens, which has a western Mediterranean distribution; and the eastern Mediterranean var. collinus, which is also not silky and can be described by long petioles and peduncles....read more on Wikipedia.
