S. sine?isis is an extremely variable species in the foliage and 

 in the form of the lip, consequently numerous species and varieties 

 have been recognized among its many forms by some authors only 

 to be reduced by others. Taken altogether, the species of the sec- 

 tion Euspiranthes seem to be remarkably plastic under the influ- 

 ences of environment, and adapt themselves readily to the most 

 diverse conditions of soil and climate.
