Relation structures
Names can be linked through the following relations: synonymy, misidentification, determination, homonymy, non, and pro parte. These are used to trace the history of the uses of a name.
 A relation may have two or three branches.
 Synonymy, determination, misidentification, and pro parte relations have three branches, the authority for the relation and the two names that the authority considered related.
Synonymy: a three-branch relation using a solid black line to the left of the names.
The two names the authority considered related are linked to the name the authority considered valid,
indicated by a black box, which is followed, at the end of the line, by the name of the authority and the
bibliographic citation to the source of the information.
The relation shown here should be read: Carlgren (1928) considered Dimyactis duplicata Pax, 1922,
to be a junior synonym of Edwardsia kerguelensis Studer, 1879, under the new combination Halianthella kerguelensis (Stud.).
Determination: a three-branch relation using a solid gray line on the left side. The name initially used for the specimen(s) is linked to the first mention of the name and the name the authority considered valid, indicated by a gray rectangle, which is followed, at the end of the line, by the name of the authority and a bibliographic citation to the source of information.
The relation should be read: Dunn (1981) determined that Condylactis sp. of Saville-Kent (1897) is Heteractis aurora (Quoy & Gaimard, 1833).
Misidentification: a three-branch relation using a solid gray line on the right side. The name that was misapplied - the first in this example - is linked to the first mention of the name the authority considered valid and to the name used by the authority, which is indicated by a gray rectangle, and which is followed, at the end of the line, by the name of the authority and a bibliographic citation to the source of the information.
The relation should be read: Carlgren (1938) found that Bolocera longicornis Carlgren, as used by Stephenson (1918) is Bolocera capensis Carlgren, 1928.
Pro parte: a three-branch relation using a dashed red line on the right side. The middle name is the one the authority considered was erroneously applied to some specimens. It is linked above to the name considered by the authority to be the senior synonym, and below (indicated by a red rectangle) to the name considered valid, followed, at the end of the line, by the name of the authority and a bibliographic citation to the source of the information.
The relation should be read: Carlgren (1928) found that some of the specimens described by Pax (1922) as Rhytidactis antarctica are, in fact, Halianthella kerguelensis (Stud).
Homonymy and non have two branches, the authority for the relation and the name addressed.
Homonymy: a two-branch relation using a dashed black line to the left of the names.
The name the authority considered homonymous (on black) is linked to the name the authority considered valid;
the original description of that species is indicated by a rectangle of same color outlined in black.
The status of the homonymous name is indicated on the green line to its right.
The relation shown here should be read: The status of Actinia aurora of Gosse, 1854,
as a junior homonym of Actinia aurora of Quoy and Gaimard, 1833, was recognized by Dunn (1981),
who used the name Heteractis aurora (Quoy & Gaimard, 1833) for the latter.
Non: a two-branch relation in red to the right of the names. The name the authority considered non
(imposed on black) is linked to the name considered valid by the authority, indicated by a red box, and which is followed,
at the end of the line, by the name of the authority and the bibliographic citation to the source of the information.
The relation shown here should be read: Dunn (1983) considered Bolocera longicornis Carlgren, 1891,
not to be a synonym of Bolocera kerguelensis Studer, 1879.
Relations are indicated to the left (synonymy, homonymy, and determination) and the right (misidentification, pro parte, and non) of the list of
names in the graphical display.
Left side relations in a synonym list:
- synonymous names are linked by solid black lines
- determination relations are displayed with solid gray lines
- homonyms are linked by dashed black lines
Right side relations in a synonym list:
- misidentifications are linked by solid gray lines
- pro parte relations are linked by dashed red lines
- non relations are indicated with solid red lines

REMARK:
The line for active relation (the one on which you are working) is highlighted in blue. You can select a relation from the Relations tab in the Entry form. Once you stop editing, the line will acquire the appropriate color.
