This dataset contains a list of the presence, habitats and herbarium vouchers of the species of the Siphonocladales sampled at the Kenyan coast. Field work was carried out on a yearly basis from July 1985 till September 1992. Sampling was done by walking or wading at low tide and by snorkeling at high tide. All algae were collected in separate pots or bags. All specimens were determined with a Reichert light microscope and a Wild stereoscopic binocular. The data were digitized by VLIZ from the original report: Verstraete, H. (1993). De Siphonocladales (Chlorophyta) van de Keniaanse kust. The Siphonocladales (Chlorophyta) of the Kenyan coast..
