DOUBTFUL SPECIES. 
Thwaites gives (Enum. 333) Thalassia stipulacea, Koen. (Halophila stipulacea, 
Aschers.), as being found at Trincomalee by Dr. Harvey. I have seen no specimens 
from Ceylon, and suspect that H. ovata is intended. H. stipulacea is a Red Sea 
species with short petioles, and is remarkable for its (when dry) bullate leaves.
