SENSITIVE FERN. Onocle'a sensi'bilis. 



SENSITIVE PLANT. Mimo'sa pu'dica. There are 

 several other plants which give evidence of being sensi- 

 tive. The Venus Fly-trap (Dion/z'a musci'pula) has 

 jointed leaves, which are furnished on their edges with a 

 row of strong prickles. Flies, attracted by honey which 

 is secreted in glands on their surface, venture to alight 

 upon them. No sooner do their legs touch the hairs on 

 these parts than the sides of the leaves spring up, and, 

 locking their rows of prickles together, squeeze the 

 insects to death. O'xalis sensiti'va and Smi'thia sensiti'va 

 are similarly irritable, as the filaments of the stamens of 

 the Barberry. One of this sensitive tribe, Desmo'dium 

 gy'rans, has a spontaneous motion ; its leaves are fre- 

 quently moving in various directions, without order or 

 co-operation. When an insect inserts its proboscis be- 

 tween the converging anthers of a Dog's Bane (Apo'cynum 

 androscemifo'lium), they close with a power usually 

 sufficient to detain the intruder until death.
