Abstract
An investigation was made to determine the form of nitrogen preferentially used by the liverwort S. texanus. When ammonium nitrate was the only source of nitrogen supplied, the plants retained approximately equal proportions of ammonium and nitrate. When organic nitrogen as. tryptone was available in addition to ammonium nitrate, ammonium nitrogen was used but there was evidence that the organic nitrogen was being retained in a larger proportion than the ammonium or nitrate. The addition of the organic nitrogen had a pronounced beneficial effect upon the growth and development of the colonies.
