Botany and Zoology. 403 
In Funkia and Allium fragrans, in the seeds in which Strass- 
burger discovered adventive embryos, we have something similiar 
to the apogamous ferns; first, in the presence of apparently regu- 
larly formed but functionless female organs ; secondly, in the 
presence of apparently active pollen, and thirdly, in the substitu- 
tion of adventive embryos for the regular embryo-formation. 
Citrus aud Coelebogyne, in which Strassburger also found adven- 
tive embryos, probably belong to the same class as AWiwm and 
Funkia, as may, also, species like Huonynuss latifolius, many 
Ardisiw, ete., in which polyembryony often occurs 
to be added the numerous species, varieties, and races of culti- 
1s produced in surpassing profusion. W. GF.
