Abbot, is very characteristic. Of the two other figures in the plate, the 
upper one is referable to a smaller state of R. fraxinea, and the lower

other specimens we have seen. ug j

yet from the frequent occurrence of various transition states, it would- 
appear that he is quite correct in saying of fastigiata “ vix est nisi varietas
