Breeding system of three taxa of Chaenorhinum (D.C.) Rchb. (Scrophulariaceae) of the Iberian Peninsula: C. origanifolium (L.) Fourr. subsp. cadevallii (Bolos & Vigo) Lainz, C. origanifolium (L.) Fourr. subsp. crassifolium (Cav.) Rivas Goday & Borja and C. tenellum (Cav.) Lange

Abstract: SummaryBreeding system and flowering phenology are studied in three taxa of Chaenorhinum: C. tenellum. a geographically restricted species from East-Central part of the Iberian Peninsula, and two subspecies of C. origanifolium, subsp. cadevallii and subsp. crassifolium. both of them with wide geographic distributions. Flowering phenology, from bud to ripe fruit, can be separated into six stages, taking 40 days in both subspecies of C. origanifolium, and 29 days in C. tenellum. C. tenellum is self-compatible and both subspecies of C. onganifolium are self-incompatible. This self-incompatibility is reported here for the first time for Chaenorhinum species. Comparison between the reproductive system and wideness of the distribution area fits well with predictions that self-incompatibility is more likely in widespread species than those from restricted areas.
