steins. There is no technical character separating L, heermannii 

 Greene from L. eriophorus Greene and the former, therefore, is con- 

 sidered by the writer but a variety of the latter, a variety with smaller 

 flowers and less pubescence. It is not always possible to distinguish 

 clearly between the species and the variety as occasionally small- 

 flowered plants appear to have the pubescence of the species and 

 large-flowered plants have the general aspect of the variety. The 

 limit of 5 mm. for length of flower in the variety is arbitrarily chosen 

 and holds true only in general.
