" Apparently unknown to recent botanists ; but having ' opposite cordate leaves,' it 

 can hardly be of this genus." — A. Gray. 



There is a specimen in Kew Herbarium of Andrieux's 286, upon which De Candolle 

 founded this species, and there is no doubt it belongs to the genus Palafoxia as limited 

 by Bentham and Hooker, and to Polypteris as restored by Gray himself; therefore 

 Polypteris latifolia, Hemsl. Indeed it is very near P. lindeni, A. Gr., which. has the 

 lower leaves strictly opposite, like P. latifolia.
