had been removed from the anther. I have also repeatedly placed minute 

 insects on the lip, thus causing them to become entrapped, and in several 

 instances I have seen these escape from the flower in the manner described 

 above, bearing poUinia on their backs. The whole of the New Zealand species 

 of Pterostylis are fertilized in the manner described above; and, according 

 to the researches of the late Mr. Fitzgerald, it is also the manner employed 

 in the Australian species.
