Dictionary of botanic terminology - index of names

Adjective: Relictual 
  Surviving remnants of a formerly widespread species or group in certain isolated areas but which is extinct over much of its former range.  
In biology a relict is an organism that at an earlier time was abundant in a large area but that now persist at only one or a few small areas. A survivor(s) from a previous geological era or from earlier (different) climatic conditions, a remnant of an otherwise extinct flora or fauna in an environment much changed from that in which it originated
The distribution of a relict is characterized as endemic. An example of a relict is a remnant or fragment of the vegetation of an area that remains from a former period when the vegetation was more widely distributed.
The term "relict" can also refer to an ancient species that survives while related species go extinct, the last survivor of an otherwise extinct group The Gingko biloba is an example of this type of relict.
