Giseke's difficulties. But afterwards, in 1771, he 

 had the good fortune to spend some time at Upsal ; 

 and he narrates a conversation which he held with 

 the great teacher on this subject, and which I think 

 may serve to show the nature of the difficulty ; 

 one by no means easily removed, and by the general 

 reader, not even readily comprehended with dis- 

 tinctness. Giseke began by conceiving that an Order

 one seed, and En/ngium, which has not an umbel,
