I know of no genus nearly related to this very curious plant, which 

 I think I cannot be wrong in referring to the Gerardiem, It has the 

 characteristic anthers of the group, and the ovules, reduced to a pair in 

 each cell, are not without parallel, but I do not know any scrophu- 

 lariaceous plant with a similar calyx, the two orbicular, entire and 

 quite equal divisions of which, coherent towards the base, each \7ith an 

 adpressed bracteole opposed to its base, remind one of the foliaceous 

 bracteoles of some Tlmnhergice^ or of the two outer enlarged sepals of 

 Uildehrandtia.^J). Oliver.
