Cymodocea nodosa (Ucria) Ascherson is the most common seagrass in the Canary Islands. Data
about its insular distribution as well as observations on its flowering, fruiting and seed germination
are shown. Cymodocea nodosa forms scattered meadows mainly along the southeastern coasts of
these islands. The reproductive phenology was studied in meadows at E1 M6dano, south of Tenerife.
Flowering was detected from March to July, when fertile shoots were observed. Fruiting began in
April and fruits were observed attached to shoots until December. Throughout the year numerous
fruits were detected buried in the sediment. Seed germination was observed from February to Septembe
