In Volkens, 318, type of Volkensiophyton, Lindau, I find the calyx of 5 segments 

 (not 4 as given by Lindau) and tlie 2 posticous anthers 2-celled (not l-c^Ued as given 

 by Lindau). The pollen is said in Lepidagathis to be hor.eycombed (which is not said 

 of the pollen of Volkensiophyton) ; but the pollen is really the same ; the reticidation 

 of the extine in Lepidagathis is exceedingly shallow, and in places broken up and passing 

 over into mere granulation.
