This is I'ropyxis amoyplui'. Schroter: l)ut aside from the 

 peculiar coating of the teleutospore there is nothing to separate 

 the species from Puccinia. The uredoform would have been 

 considered a good Lecijthia. and is much like that of Melaiiq)- 

 sor(( on willows. The teleutosori on the upper side of the leaf 

 are compact, the spores crowded together. On tlie under side 

 the s])ores are diffusely associated in the sori.
