The most easily procured species are D. binata^ which some 

 what resembles D. dichotonia, but is of dwarfer habit and more 

 highly coloured than the last-named. D. cape?isis is a most 

 distinct and desirable sort, of compact and pretty growth ; it 

 gets distinctly red under the influence of the sun's rays.

DlON^A MUSCI- 



PULA. — Of the 

 whole section of 

 Insect ivorous 

 Plants the Dionaea 

 is the most in- 

 teresting (Fig. 

 411). It is 

 familiarly known 

 as Venus's Fly- 

 trap, which popu- 

 lar name is derived 

 from the sensitive- 

 ness set up by an 

 insect or some 

 other small object 

 coming in contact 

 with one or more 

 of the three 

 bristles which are 

 placed in the 

 centre of each 



lobe of the leaf. Immediately these are touched the outer edges 

 suddenly close up, which prevents the escape of the fly or other 

 insect which may have intruded. This naturally causes the im- 

 prisoned insect to struggle more vigorously to gain its freedom. 

 In so doing it is in constant contact with the sensitive bristles, 

 which causes the sides to become compressed more firmly, 

 until at last the unfortunate insect becomes so wedged that it 

 cannot move, and it ultimately dies from suffocation. Soon after
