No. 494] FAS CI AT IONS OF KNOWN CAUSATION 83 



and in numerous species, in fact, in so many species, in so 

 many genera and in so many families, among fungi, 

 among gymnosperms, among monocotyledons and dicoty- 

 ledons, on herbs, on shrubs and on trees, that the assump- 

 tion appears justified that fasciation may be expected to 

 make its appearance at some time, in some part, in any 

 species. This is the view held by Sorauer, 13 but de Vries 14 

 does not make so sweeping a statement. 



Fasciations may be propagated vogetatively, for in- 

 stance, by means of tubers, as in Oralis crcnata or 

 through cuttings, as was done at the Missouri Botanical 

 Garden for fasciations of the tomato, Solarium Lycoper- 

 sicnni, snap-dragon, Antirrhinum ma jus, hen-and-chick- 

 ens, Echeveria glauca and others. Fasciations may also 

 be transmitted through seed. Among the best known 

 instances is the cockscomb, Celosia cristata and its varie- 

 ties, which, because of this abnormality, is cultivated in 

 gardens. It is a form which, like the cockscomb ama- 

 ranth, Amaranth us cristatus, has been known for cen- 

 turies to exist, and is always propagated through seed. 

 Recently it has again been shown for Mnnting's Srdunt 



The possibility of the transmission of the fasciated 

 character to the offspring, had already been recognized 

 by Godron ls who, however, says: "Les fascies sont rare- 

 ment hereditaires et jamais d'une maniere absolue." 

 While the truth of the latter part of the statement has 

 been borne out by subsequent work, in the light of experi- 

 ments carried on during the last twenty years, and espe- 

 cially those of de Vries, 1 " the first part should be amended. 



Fahigkeit zur Fasciation ist bei alien Pflanzen voraus zu setzen. "
