osculant

Meanings

2. 2
   adj

   closely joined, touching, or adhering

From Latin osculans, osculantis, the present participle of osculari, 'to kiss.' The underlying image of touching or meeting led nineteenth-century naturalists to apply osculant to organisms or groups that appear to connect neighboring taxonomic divisions.
