Carnivorous Seed Plants: Sources and References1


Ordinarily plants are considered the primary food producers while animals feed upon plants directly or indirectly. A relatively small group of the vascular or higher plants feed upon animals. These “carnivorous” plants3 manufacture their own food but because of the special environment in which they grow, must supplement their intake with the nitrogen from animal tissues. Yet some insects are able to live in the traps of carnivorous plants in a Symbiotic relationship. For a number of years on into this century following the work of Charles Darwin, there was a considerable amount of research and observation made on these strange plants. There are, however, relatively few books on the subject.
