1118. P. saxifraga L. (Loew, ' Bliitenbiol. Floristik,' pp. 379, 389, 393 ; Herm.] 

 Miiller, 'Fertilisation,' pp. 277-8, ' Weit. Beob./ I, p. 304 ; Knuth, ' BL u. Insekt. a. d. \ 

 nordfr. Ins.,' p. 155 ; Schulz, ' Beitrage,' I, p. 44, II, pp. 84, 91, 190.) Both Gelmi and 

 Schulz state that this species resembles the chief form of P. magnum as regards flower 

 mechanism. It is mostly andromonoecious, but now and then gynodioecious. (CfJ 

 the last species.) 



At Ruppin, according to Warnstorf, the umbellules of primary umbels bear! 

 hermaphrodite flowers ; those of the secondary umbels marginal hermaphrodite 

 and central male ones.
