lv INTRODUCTION. 
the most unmistakable evidence of self-fertilization in genera far removed from each 
other in every respect. Only a few examples need be mentioned here, as they are 
dealt with in the text. Such examples are Eria excavata, Dendrobium crepidatum, 
Calanthe Manni. Most of the species in Goodyereae, notwithstanding that the 
polinar appendages in this tribe appear to be suitably formed for removal by insect 
agency, are also self-fertile. The subject is one which we believe would yield most 
interesting results in the hands of a careful and patient observer.
