ORCHIDACEiE 



exhibit a wide range of variation in the form of the inflorescence H.Leprieuri 

 and in the relative proportions of the divisions of the petals and 

 labellum. Cogniaux's observations tend to show that great vari- 

 ation may be expected in the anterior division of the petal, this 

 being either well developed or much reduced. Warming's figure 

 shows the anterior division of the petal to be more slender than 

 in the material chosen for illustration here. (Plate 70.)
