tions plant families Rubiaceae and Caprifoliaceae among examples of groups separated by no 

 absolutely trenchant character. Considers recognition of geographical subspecies a useful

 prove inappropriate, avoiding too free use of those derived from personal or geographical 

 names. — 0. A. Stevens.
