Morphotaxonomic Study of Algal Epiphytes from Ipomoea aquatica Forssk. (Convolvulaceae) found in Laguna de Bay (Philippines)

Abstract

© Universiti Putra Malaysia Press Epiphytic algae existing on submerged leaves, stems and roots of Ipomoea aquatica Forssk. (Convolvulaceae) found in Laguna de Bay was studied. Examination of the prepared specimen showed a total of 15 infrageneric taxa belonging to 10 orders, 13 families, 15 genera and 15 species were identified during the study period. Of these taxa, the occurrence of a rare photosynthetic euglenoid, Cryptoglena skujae Marin and Melkonian is reported as new record for the Philippines. Two species are also presented here based on current accepted taxonomic names and these are Limnococcus limneticus (Lemmermann) Komárková, Jezberová, O.Komárek & Zapomelová, and Anabaenopsis circularis (G. S. West) Woloszynska & V. Miller in V. Miller. The algal taxonomic records reported in this survey expand the knowledge regarding diversity and distribution of epiphytic algae from aquatic macrophytes found in Philippine freshwater environment.
