The largest angiosperm genus Astragalus exhibits a wide range of morphological variation regarding flowers, inflorescences and especially pods. As a result, some of its species are widely distributed, while others are local endemics and often threatened. It is of significant interest to trace features which provide a higher success for some species under conditions, where their relatives are depressed. Four perennial species of Astragalus from central Russia served as models for this comparative survey, viz. A. cicer, A. glycyphyllos, A. arenarius, and A. danicus. The two former species are widely distributed and rarely included into the regional Red Lists, while the two latter are comparatively rare and considered endangered in several regions. Only a relatively small fraction of ovules develops into fully mature seeds in all four species. Basing on the results of comparative study, it was hypothesised that the main sources of prosperity are a high potential productivity (measured as ...a number of ovules per seasonal shoot) and pronounced seed dormancy, typically physical. A number of produced ovules is substantially dependent on synflorescence morphology. The feature common for all examined species of Astragalus and distinguishing of the whole genus is an unusual biseriate arrangement of ovules in an ovary, which is probably adaptive for many-seeded fruits exhibiting non-random seed abortion.
