When Iwatsuki and Sharp (1967) combined the Asiatic Solmsiella ceylonica (Thw. & Mitt.) C. Müll. with the North American S. biseriata, they stated that the variation seen in the foliation is a response to environmental conditions. The collection of this very hepatic-like moss from Mindanao Island supports their contention. The orientation ofthe ventral leaves and the inflexed lower leafmargins ofthe dorsal leaves show various angles of alignment and degrees of inflexibility. The marginal row of leaf cells are papillose in Philippine specimens. Rhizoids are coarse, thick-walled and finely papillose. Capsules are eperistomate. The other Asiatic collection of S. biseriata not included in the distribution map prepared by Iwatsuki and Sharp (1967) is from Mt. Dinghu, Guangdong Province, People's Republic of China (Lin, Yang & Li, 1982). Through the kindness of Prof. P.-C. Lin ofthe South China Botanic Institute, I was able to study the Chinese specimens which exhibit similar phenotypic variation in the foliation and leaf form.
The genus Solmsiella C. Müll. is a new addition to the Philippine moss flora.
