Carnivorous plant often waterlogged, which favours the production of toxic ions such as ammonium, and its pH is an acidic 4 to 5. Ammonium can be used as a source of nitrogen by plants, but its high toxicity means that concentrations high enough to fertilise are also high enough to cause damage. However, the habitat is warm, sunny, constantly moist, and the plant experiences relatively little competition from low growing "Sphagnum" moss. Still, carnivores are also found in very atypical habitats. "Drosophyllum lusitanicum" is found around desert edges and "Pinguicula valisneriifolia" on limestone (calcium-rich) cliffs. In all the studied cases, carnivory allows
American Type Founders typecasting operations moved to the Kelly plant in Elizabeth. Salesmen were put on a commission basis. Inventories were cut, faces discontinued, and production of several models of Kelly press as well as the Klymax Feeder was shut down. ATF was released from court supervision in 1936 and in 1938 a sales study was made making the following observations: the Kelly press was obsolete, body type was now the exclusive province of line-casters and display type would have to be the mainstay of type production, almost half of what ATF was selling was other manufacturers products that could easily be made
