There continues some debate in the literature and between seagrass taxonomists on the details particularly below sub class on the correct classification.
Tropical Seagrass Identification
For example, the Angiosperm Phylogeny Group published several papers recommending angiosperm classification, and is considered by many to represent the “standard”. However many prominent seagrass taxonomists disagree.
This classification is an opinion of Seagrass-Watch HQ based on the best information available.
Seagrass-Watch HQ recommends that users exercise their own skill and care with respect to their use of this classification and that users carefully evaluate the accuracy, currency, completeness and relevance of the material on the web site for their purposes.
