1181. O. glandiflora Hofifm. (=Daucus grandiflorus Scop.). (Herm. MuUer, 

 ' Weit. Beob.,' I, pp. 307-10; Schulz, ' Beitrage,' II, pp. 86, 91-2, 190.) — This 

 white-fiowered species is andromonoecious, according to Schulz, but Hermann Miiller 

 tays that it may also be gynomonoecious. The hermaphrodite flowers are homo- 

 gamous. The central flowers of the umbellules are male, with vestigial ovaries, but 

 neither styles nor stigmas ; their petals are small and incurved. The marginal 

 flowers are hermaphrodite, or sometimes (Herm. Miiller) fertile female ones ; the 

 external petal is enlarged. Sometimes the reproductive organs of male, female, and 

 hermaphrodite flowers are completely abortive. In each flower at the margin of an 

 entire umbel the external petal is enlarged into a deeply bifid expansion over 

 I cm. long. 



Although the plant grows among corn, it is very conspicuous, owing to the 

 large marginal flowers, and the inflorescences are visited by many insects, which 

 effect the crossing of different umbels and frequently of difTerent stocks, if they 

 alight on the margins of the umbels. Schulz says that automatic self-pollination 

 is possible only for a short time in the homogamous hermaphrodite flowers, as the 

 stamens quickly bend outwards. 



Visitors. — Schulz (Tyrol) noticed numerous flies and beetles, more rarely small 

 Hymenoptera.
