| Summary: | <p class="MsoNormal" style="margin-bottom: 0.0001pt; line-height: normal;"><span style="font-size: 12pt; font-family: " lang="EN-US">The acuatic, helophytic and pleustophytic vegetation of the Laguna de La Herrera, on the southwestern border of the high plain of Bogotá at 2550 m was studied following the Zurich- Montpellier approach. The communities recognized were: terrestrial community of <em>Phytolacca</em> <em>bogotensis; </em>helophytic communities of <em>scirpus californicus </em>and <em>Typha angustifolia ; scirpus</em> <em>californicus ; Polygonum punctatum ; Rumex obtusifolius </em>with <em>Polygonum punctatum; Bidens</em></span><em><span style="font-size: 12pt; font-family: " lang="EN-US"> laevis ; Hydrocotyle ranunculoides. </span></em><span style="font-size: 12pt; font-family: " lang="EN-US">Pleustophytic communities of <em>Limnobium laevigatum; Azolla filiculoides </em>with <em>Lemna </em>cf. <em>gibba </em>and <em>Eichornia crassipes. </em>The structure, floristic composition and<em> </em>ecological aspects were also considered.
