I must first say, that I think the stylopodium only meta- 

 morphosed, specialised part of the style, differing from the disc, 

 which represents in my opinion an organ sui generis. Stylopodium 

 is a tuberculum styliferum (Gaertner), basis incras- 

 sata stylorum (Candolle), verdickter Basalteil des 

 Griffels (Pax), an enlargement or an expansion at 

 the base of a style [k. Gray), — a discus epigynus „ent- 

 wickelt sich aus dem Bl uet cnb о den... rings um die Ba- 

 sis des Griffels" ^; I suppose, that they are easily distinguishable 

 on the basis of their embryogeny,. although, judging by the lite- 

 rature it is possible to think that the stylopodium and discus of 

 Ammiaceae are synonimes ^

 einem Walle umschlossene Vertiefung" — disc of Saniculoideae and the 

 typical „Grifffelpolster" — stylopodium of great number of Apioideae.
