The most common, widespread and polymorphic species of the genus in Turkey. In the characters of size, shape and number of leaflets, indumentum, flower colour, size, shape and proportions of standard, wings and keel, and shape and indumentum of the lomentum, it is extremely variable. Although H. varium itself is a most polymorphic species, its pattern of variation may be further extended by hybridisation or introgression with H. pestalozzae, H. syriacum, and H. nitidum. The differences between these four species are unsatisfactory, and further work is needed before their interrelationships and taxonomy can be put on sounder foundations. |
