336. Berula Hoffm. 



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

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

 iumbellules frequently possess three styles (Warnstorf, Verh. bot. Ver., Berlin, xxxviii, 

 J1896). 



337. Sium L. 



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

 p. 304; Schulz, 'Beitrage,' I, p. 44, II, p. 190; Warnstorf, Verh. bot. Ver., Berlin, 

 xxxviii, 1896; Kerner, 'Nat. Hist. PI.,' Eng. Ed. 1, II, p. 325 ; Knuth, 'Bliitenbiol. Beob. 

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

 as andromonoecious, with markedly protandrous hermaphrodite flowers ; the umbels 

 iof 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 

 I 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.
