Oithago segetum (Caryophyllefe). — The first leaves produced 

 by young seedlings, rise up and close together at night. On a 

 rather older seedling, two young leaves stood at noon at 55° 

 above the horizon, and at night at 86°, so each had risen 31°. 

 The angle, however, was less in some cases. Similar observations 

 were occasionally made on young leaves (for the older ones moved 

 very little) produced by nearly full-grown plants. Batalin 

 says ('Flora,' Oct. 1st, 1873, p. 437) that the young leaves of 

 Stellaria close up bo completely at night that they form together 

 great buds. 



Sida (Malvaceae). — The nycti tropic movements of the leaves 

 in this genus are remarkable in some respects. Batalin informa
