Mr. Edwin Ashby exhibited pressed specimens of Orchids from 

 South Australia including a number of the " spider-like" members 

 of the genus Caladenia, and the green-hooded forms of the genus 

 Pierostijlis : many of these have a sensitive labellum which on the 

 entrance ok' an insect closes up the opening for a short period ; 

 Mr. Ashby suggested that tliis was for the purpose of fertilization. 

 A member of the genus Thehfmitra, which only open their bright- 

 coloured petals in hot bright sunshiny days, and two species of 

 Calei/a were exhibited, both extremely local in that state, and both 

 providt^d with a sensitive labellum, which, on being touched, folds 

 up in two separate movements. 



A species of Diaris intermediate between D. macidata and 

 D. longifolia, although now a fixed form, seems certainly to have 

 been derived by hybridization. For many years l^elore it \^as 

 described by Dr. Rogers as Diuris palachila, Mr. Ashby had knovMi 

 it under his own name of 7i)/brida, thinking it could hardly deserve 

 Bpecific rank. 



A very beautiful form known as Caladenia tuteJata, ]{. S. Rogers,
