Githago segetum (Caryophylleae).—­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 55o above the horizon, and at night at 86o, so each had risen 31o.  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 so completely at night that they form together great buds.

Sida (Malvaceae).—­the nyctitropic movements of the leaves in this genus are remarkable in some respects.  Batalin informs [page 322] us (see also ‘Flora,’ Oct. 1st, 1873, p. 437) that those of S. napaea fall at night, but to what angle he cannot remember.  The leaves of S. rhombifolia and retusa, on the other hand, rise up vertically, and are pressed against the stem.  We have therefore here within the same genus, directly opposite movements.  Again, the leaves of S. rhombifolia are furnished
