Variation and control of growth-form in the moss Hylocomium splendens
The moss Hylocomium splendens has both sympodial and monopodial forms of growth. One aim of this study was to document the growth-form of shoots from different populations. A further aim was to discover the extent to which genetic or environmental factors determine whether monopodial or sympodial gr...

The moss Hylocomium splendens has both sympodial and monopodial forms of growth. One aim of this study was to document the growth-form of shoots from different populations.

Switching between growth-forms within shoots occurs in most populations. Populations in forest habitats in temperate to mid-Arctic environments have predominantly sympodial shoots whereas shoots of populations from tundra habitats, in high-Arctic environments or at high altitudes, are predominantly monopodial.
