Parasitic flowering plants are strikingly impressive and beautiful and hold many surprises of both general and scientific interest. Parasites also have great influence on the quality of human life when attacking crop plants. Some parasites have since early times appealed to our imagination and have been part of religious or folkloristic events and used as gifts to royalties. This beautifully illustrated book covers all parasitic families and most of the genera. It also discusses the establishment of the parasite, the structure and function of the nutrient absorption organ (haustorium), and how the parasites are pollinated and dispersed as well as their ecology, hosts, and evolution. The book is written in a mostly non-technical language and is provided with a glossary and explanatory boxes.

The bottom zone of the pitcher of the carnivorous plant Sarracenia was investigated using light and electron microscopy. The rectangular epidermal cells have dense cytoplasm with a large nucleus, many mitochondria and chloroplasts. The cuticular membrane is thin, its cutinized layer becoming discontinuous during the maturation of the pitcher. The anticlinal walls of the epidermal cells are partly lignified and seem to permit apoplastic diffusion. The hypodermal cells are provided with a secondary suberized wall, and a silver hexamine positive “plug” fills the gap between neighbouring hypodermal cells. The hypodermis therefore resembles the bundle sheath cells of certain grasses. Simple pits traversed by many plasmodesmata connect each hypodermal cell with its neighbouring epidermal, hypodermal and mesophyll cells. The structure and development of the pitcher epithelium is described and its function discussed.
