| Abstract: | The spatial development of circular auxoclones of Spartina townsendiicolonizing bare mud or muddy sand is described. It is shownthat enlargement of the auxoclones is accompanied by a changein shoot density distribution and development of a concentricpattern. Additional rings of high shoot densityare added as the auxoclone increases in diameter and those inthe centre are maintained. The number of rings is proportionalto the diameter, and auxoclones reached the same complexityat the same diameter on different substrates. This type of developmentis discussed in relation to Spartina morphology. |
