The plant on which this genus is based is closely allied to 

 Cymaria, Benth., the hitherto known species of which also seem 

 to be restricted to limestone rocks. While, however, Acrymia 

 agrees with Cymaria as regards its peculiar inflorescence and 

 repeats the characters of calyx and fruit met with in that genus, 

 it differs from Cymaria in having a 2-lobed upper lip which does 

 not conceal the anthers. In Cymaria the upper lip is oblong, 

 entire and vaulted over the stamens whose anthers are distinctly 

 2-celIed. Except in being much smaller the corolla of Acrymia 

 resembles rather closely the corolla of Ajuga, a genus in which 

 the anther-cells, though usually discrete, are sometimes ultimately 

 confluent. In Acrymia^ however, the anthers appear to be 

 1-celled from a very early stage. The habit of Acrymia recalls : 

 that met with in the group of species belonging to the genus 

 Gomphostemma, which includes G. om/wm, Wall., and G. Maslwsii, 

 Benth., and is unlike that met with either in Cymaria or in 

 Ajuga.
