ANGIOSPERMAE—DICOTYLEDONES 



378. Myrrhis L. 

 1199. M. odorata Scop. (Herm. Muller, ' Fertilisation,' p. 278, ' Weit. Beob.,' 

 I, p. 311; Schulz, 'Beitrage,' II, p. 191.) — Schulz describes this species as andro- 

 monecious, with protandrous hermaphrodite flowers. Herm. Miiller says that the 

 last flowers which appear are purely male, their small petals falling oflf without ovary, 

 styles, or stigmas having developed. These flowers consequently provide pollen for 

 fertilizing the youngest hermaphrodite ones.
