segments', lateral staminodes and labellum should be spread out 

 flat, and, as far as possible, should not overlap one anotlier. Under 

 moderate pressure the flowers soon dry, and the paper actually 

 containing the flowers should not be changed until drying is 



complete. 



As it seems likely that species of Iledychiiim^ may attain con- 

 siderable economic importance in the future, it is to be hoped 

 that correspondents desiring names for plants of this genus will 

 forward specimens which have been dried according to the instruc- 

 tions here given. 



EXPLANATION OF PLATES AND FIGURES IN TEXT. 



The figures represent the flowers, all three-quarters natural size, 

 of the species" dealt with above. The various floral parts in the 

 figure of H. coronarium, Koenig, have been given distinguishing 

 letters, u key to which is given below. As the figures of all the 

 flowers are drawn approximately with the same orientation, it will 

 be easy to determine the different organs by comparison with this 



one figure and the key.
