put the bibliographic information of the source paper here e.g. name of the person who converted the original to this format Sometimes the description would say "basal tubercles not markedly longer than distal ones (except in sterile fruits)". We will put 'except in sterile fruits' in organ_constraint for the length character. parallelism_constraint is used to indicate if the description about a structure (or an entity) does not follow the parallelism principle. In Flora of North America, for example, if an author describe a set of characters for a genus, the authors are required to describe the same set of characters for other genera in the same family. However, the authors sometimes can not follow this principle, and to indicate they deviated from the rule, they use () to enclose the characters they described for a genus but not for other genera. We used parallelism_constraint = "true|false|possible" to indicate if the description of a structure deviated from the parallelism rule. This attribute also applies to characters and relations based on the same idea. The taxon_constraint is used to indicate an entity/character/relation is applicable only to a specific taxon. For example "basal tubercles rounded (except in m. parvifolia and m. bostockii)". The character is not applicable to all taxa in the genus, so we'd use taxon_constraint = "except in m. parvifolia and m. bostockii" for the shape character of basal tubercles. the inferred_constraint is used to hold the structure that is inferred by the software, for example, to disambiguiate a non-specific structure, for example apex may have an inferred_constraint leaf to refer to leaf apex.
