may be obtained. Other districts must needs be supplied 

 by friends or by some botanical supply company. (The 

 Cambridge Botanical Supply Co., Cambridge, Mass., adver- 

 tises that it will obtain botanical materials for teachers.) 

 Plants may be kept growing in the laboratory if the pots are 

 kept immersed in several inches of water. Dried leaves 

 may be kept from season to season, being soaked up in 

 water when needed. Species of Nepenthes are often grown 

 in conservatories. 



II. The Darlingtonia is difficult to obtain except occa- 

 sionally from florists who deal in native plants. 1 It is easily 

 grown in the same way as Sarracenias are. 



IV. The Venus Flytrap is very restricted in its range, 

 but is fairly readily grown in sand in a pot immersed in 

 a few inches of water. It may be obtained through dealers 

 in native plants. 1 



VII. The teachers in the eastern United States can obtain 

 Drosera species. Others may sometimes obtain them from 

 florists. They should be grown in peat and Sphagnum, but 

 do not flourish as well as the plants previously mentioned. 



The Bladderworts (Utricitlaria sp.) may also be used if 

 accessible to the teacher, as they are in much of the country 

 east of the Rocky Mountains. 



If laboratory material is unobtainable, the teacher will lect- 

 ure upon this chapter and show specimens or illustrations.
