This is one of the series of varieties to be met with in East 

 Asia, which extend thence throughout North Asia, Europe and North 

 America, and which are intimately related that many authors re- 

 garded them as belonging to the true Thymus Serpyllum. Still this 

 is distinguished from Thymus Serpyllum with its stout ligneous stems 

 and bigger flowers, and so, not only from the botanical standpoint 

 but from the distributive point of view it is convenient to distinguish 

 from Thymus Serpyllum.
