A critical review of the literature pertaining to the germination and growth of the foliar embryos of Bryophyllum calycinum, Salish., has revealed that in most cases the influence of certain physiological and environmental factors upon these structures was not carefully considered. For instance, the history of the plants prior to the experimental period was not fully elucidated and, in absence of statements to the contrary, must have been largely ignored. Yet the work of Dunn (1937) indicates that the influence of "hardening" treatments may extend over as many as three following generations in this species. A common experimental error in most previous work was the lack of simultaneous control of temperature, humidity, and light throughout the time of experimentation.
