Currently parser normalizes various forma abbreviations to fm. to avoid ambiguity with abbreviation of filius. However fm. is not a common abbreviation (it is mentioned in Taxon Concept Shema, but it is not commonly used).

Do continue distinguish between filius and forma/form we are continuing normalizing filius to fil. but changing fm. normalization to a more commonly used f.
