Spiranthes Gonzalez is not closely related to any spe- 
cies known to me, but seems to be somewhat allied to S. 
sparsiflora C. Schweint. 
Juan Gonzales, for whom this species is named, is a 
native Mexican who collected a large number of orchids 
under the direction of Erik Oestlund and Otto Nagel. 
Although he apparently spelled his name Gonzales (on 
labels often Juan G.) the correct Spanish form Gonzalez 
is used in the specific name.
