Note G — OBSERVATIONS ON THE POLLINATION Of Solanum rostratum Dunal and Cassia chamæcrista L.

S. rostratum appears to be better adapted to xerophytic conditions by its extensive root system than by any adaptation for the prevention of evaporation of water. When cut down on a warm day, the plants wilt in a very few minutes. Roots extend down sometimes for more than three feet, so that the plants generally appear perfectly fresh when others around are wilted and drying up.
