Phytotelmata of pandan leaf axils represent a unique microhabitat for microalgae since this plant provides suitable environmental conditions for their growth and proliferation. The current study is the first taxonomic survey to focus on the taxonomy of phytotelm algae of Pandanus amaryllifolius (Pandanaceae). A total of 15 microalgal species were taxonomically identified and described from the collected water samples, of which six species (Lyngbya taylorii, Cyanothece aeruginosa, Eudorina elegans, Staurastrum avicula var. lunatum, Ulnaria ulna, and Gomphonema sphaerophorum) are new additional records of microalgae in the global inventory list of phytotelm microalgae. Also, the survey reported the occurrence of Staurastrum avicula var. lunatum (Ralfs) Coesel & Meesters for the first time in the Philippines. Taxonomic keys and descriptions as well as photomicrographs are presented to differentiate the species of phytotelm microalgae. The survey provided important taxonomic records on the species composition of microalgae of leaf axil tanks of plants found in the Philippines.
