(Plumbaginaceæ) follows the sun.  The shoot did not begin to revolve until nearly a yard in height; it then made a fine circle in 10 hrs. 45 m.  During the next few days it continued to move, but irregularly.  On August 15th the shoot followed, during a period of 10 hrs. 40 m., a long and deeply zigzag course and then made a broad ellipse.  The figure apparently represented three ellipses, each of which averaged 3 hrs. 38 m. for its completion.

Jasminum pauciflorum, Bentham (Jasminaceæ), moves against the sun.  A circle was made in 7 hrs. 15 m., and a second rather more quickly.

Clerodendrum Thomsonii (Verbenaceæ) follows the sun.

Tecoma jasminoides (Bignoniaceæ) moves against the sun.

Thunbergia alata (Acanthaceæ) moves against sun.

Adhadota cydonæfolia (Acanthaceæ) follows the sun.  A young shoot made a semicircle in 24 hrs.; subsequently it made a circle in between 40 hrs. and 48 hrs.  Another shoot, however, made a circle in 26 hrs. 30 m.

Mikania scandens (Compositæ) moves against the sun.

Combretum argenteum (Combretaceæ) moves against the sun.  Kept in hothouse.

Combretum purpureum revolves not quite so quickly as C. argenteum.

Loasa aurantiaca (Loasaceæ).  Revolutions variable in their course: a plant which moved against the sun.

Another plant which followed the sun in its revolutions.

Scyphanthus elegans (Loasaceæ) follows the sun.
