PLATE XIX. 
at the former, and the exception at the latter place. I have neither facts 
nor experience enough as yet to justify my attempting any induction ; it 
is possible, however, that if I am able to complete the second part of 
this volume after another year’s attentive observation, I may append 
some further notice of this plant when describing the beautiful yellow 
Ophrys (O. lutea) and some other handsome representatives of the genus 
found at Mentone. I venture to suggest the following queries as subjects 
for investigation especially bearing on the present remarks to those who 
are interested in the “ Fertilization of Orchids.” Ist, Does Ophrys 
scolopax exist at Mentone in a condition of self-fertilization? 2nd, Is 
Ophrys apifera ever indebted to insects for its fertilization? 3rd, What 
are the habits of Ophrys arachnites? The specimens figured were 
brought me on April 22nd, when this plant is in full flower. The 
habitats chosen by Ophrys scolopax are chiefly on rough banks such as 
are found in both the Eastern and Western bays. I so much doubt 
whether this plant can be really called a species, that I am unwilling to 
commit myself by saying that it can always be distinguished from any 
other Ophrys growing at Mentone.
