336. Berula Hoffm. 



1120. B. angustifolia Mert. et Koch (=Sium erectum Huds.). — All the umbels 

 of this species bear hermaphrodite flowers ; some of those in the middle of the 

 umbellules frequently possess three styles (Warnstorf, Verb. bot. Ver., Berlin, xxxviii, 

 1896). 



337, Sium L. 



1121. S. latifolium L. (Herm. Miiller, 'Fertilisation,' p. 276, ' Weit. Beob.,' I, 

 p. 304; Schulz, 'Beitrage,' I, p. 44, II, ]). igo; Warnstorf, Verb. bot. Ver., Berlin, 

 xxxviii, 1896; Kerner, 'Nat. Hist. PI.,' Eng. Pkl. i, II, p. 325 ; Knuth, 'Bliitenbiol. Beob. 

 a. d. Ins. Riigen,' 'Bl. u. Insekt. a. d. nordfr. Ins.,' p. 155.) — Schulz describes this species 

 as andrcfrnonoecious, with markedly protandrous hermaphrodite flowers ; the umbels 

 of higher order are chiefly or entirely male. According to Kerner, the hermaphrodite 

 flowers open first, and are distinctly protandrous ; their stigmas are dusted, after the 

 anthers have dropped off, by the crumbling masses of pollen which fall from the male 

 flowers of the later developed lateral umbels. Geitonogamy is thus automatically 

 effected. Warnstorf says that at Ruppin the umbellules of the primary and secondary 

 umbels bear hermaphrodite flowers ; those of tertiary umbels hermaphrodite and 

 central male ones, or male flowers only.
