The absence or the presence of stylopodia, as well as their form, 

 lias a considerable importance for taxonomic purposes. No wonder, 

 that during the last time, after Bentham \ all sciadographs, 

 especially the american ones, pay a great attention to this cha- 

 racters and that in the special literature there is already gathered 

 a large material of facts, which is good for synthesis. When we 

 turn leaves of the books of american florists and monographs, who 

 Avrote about Ammiaceae, privatly Apioideae, Drude of 

 their western Kingdom, i. e. the neogean region of concentration, 

 Ave sholl meet in the diagnosis everywhere the character: „stylo- 

 podium wanting", „stylopodium none", „stylopodium nullum, styli 

 a basi filiformes", what is wholly unknown by the representatives 

 of the Old World. 



It is known, that the absence of stylopodia by Eurasian Apioi- 

 deae we refered only to Lereschia, Boiss.; but „è singolari 

 che tutti gli autori fino a Drude dicano mancare gli stylopodî, 

 che invice sono fr a i piu grandi délia sottotribu" '^ 



This fact forced me to occupy myself more seriously with the 

 question: wath differences are there between the styles of North 

 American and of Eurasian Apioideae, how this differences are 

 expressed? The Eurasian x\pioideae, as we know, has an evi- 

 dent parallelism with the North American ones, what we cannot 

 say about Indoafrican ones. By composing this note 1 used the her- 

 barium-material [from the Imperial Petrograd Botanical Gar- 

 den, Botanical Museum of the Imperial Petrograd Academy of 

 sciences and of the Imperial Moscow University], but, lam sorry 

 to say, the collections, representing the North American Ammia- 

 ceae, that were at my use, were not large enough and I was 

 obliged, because of insufficiency of material, to base myself in a 

 considerable degree upon the sciadographic literature. 



1 Bentham in Bentham et Hooker Genera I 3 860 sq. A su- 

 perfluously large terminology was established already by Hoffmann, Genera 

 Umbellif. XIX. Comp. Koch, Nova Acta Acad. ISTat. Curios. Leopold. ХИ 

 63: „stylopodium bonas subinde notas genericas suppeditat". 



2 Calestani, Webbia 1905 180. By L. T h о m m a s i, Boiss.! the 

 stylopodia are very elongated, but by L. F 1 a h a u 1 1 i, W о r о п.! ones are 

 shorter broad-conic.
