Hybrids and the Flora of Thailand

Herein we highlight the surprising lack of records of plant hybrids in Thailand, suggest where hybrids may be sought and indicate that a range of techniques will be required to detect them. We do not comprehensively review plant hybridisation and, therefore, some topics such as hybrid zones (Harrison, 1993), introgression, species concepts and homoploid/polyploid speciation (Rieseberg, 1997) are not discussed in detail.
