367. Siler Crantz. 



1176. S. trilobum Crantz ( = Laserpitium aquilegiaefolium /acq.). Schulz 

 ('Beitrage,' II, pp. 85-6, 190) describes this species as andromonoecious, with 

 protandrous hermaphrodite flowers. The male flowers are numerous, and situated 

 in the middle of the umbellules. According to Kerner, the direction of the styles 

 and the position of the stigmas remain unchanged, but the slender filaments elongate 

 and curve in such a way that the pollen is applied to the stigmas of neighbouring 

 flowers (' Nat. Hist. PI.,' Eng. Ed. 1, II, p. 324).

368. Laserpitium L. 



1177. L. latifolium L. The flowers of this species are white or rarely reddish 

 in colour. Schulz ('Beitrage,' II, pp. 90, 94, 190) describes them as andro- 

 monoeciously distributed, those which are hermaphrodite being markedly protandrous. 

 The primary umbels usually bear hermaphrodite flowers only, those of higher order 

 chiefly male ones. According to Kerner ('Nat. Hist. PI.,' Eng. Ed. 1, II, p. 296), 

 there are short-stalked pseudo-hermaphrodite male flowers in all the umbellules, 

 surrounded by long-stalked, truly hermaphrodite ones. 



1178. L. prutenicum L. Schulz states that the yellowish-white flowers of this 

 species are all hermaphrodite, and markedly protandrous ('Beitrage,' II, p. 190).
