Pteridocalyx Wernham gen. nov. in Journ. of Bot. XLIX (1911) p. 317. 



The genus clearly finds a place in the tribe Rondeletieae, but it is 

 distinct from the rest of this tribe in the basal insertion of the stamens, 

 the bifid stipules, and the combination of contorted aestivation with 

 petaloid development of one or more of the calyxlobes. Pallasia seems 

 to be the nearest ally, but in Pallasia the aestivation is imbricate, and 

 the stipules entire.
