Variants with unwinged seeds are found throughout the range of the species, and show the same range of ecotypic variation as those with winged seeds.

Ecotypic variants:

Autumnal: Alectorolophus patulus Stemeck , Österr. Bot. Zeitschr. 47: 433 (1897).

Aestival: R. buccalis Wallr. , Flora (Regensb.) 25: 504 (1842).

Vernal: type of the species.

Montane: R. alectorolophus var. modestus Chab. , Bull. Herb. Boiss. 7: 504 (1899).

R. facchinii Chab. , op. cit. 506 (1899), from the Alps, is like 25, but with corolla-tube strongly and abruptly curved and throat of corolla open. It thus bears the same relation to 25 as does R. helenae to 24.
