82 ERYTHEA. 



The following is a list of the variationa that I recorded, but it 

 does not, by any means, include all the peculiar cases observed : — 



1. 4 outer petals, 5 inner. 



2. 4 " "4 " 



3. 4 « " 2 " 



4. 4 pointed petals and 1 round. 



5. 12 petals. 



6. 4 outer petals and 3 inner, 

 y 4 " " " 9 " 

 8. 4 " " " 6 " 



There were plants with flowers having 4, 5 or 6 petals; others with 

 flowers having 4 to 8 ; others with flowers having petals all of the 

 same number.— Margaret E. Adamson. 



Of abnormal forms, Eschscholtzia Californica is exceedingly 

 prolific. No other California plant has contributed so many cases 

 to my teratological record in the last four or five years as this 

 species. Some of these examples are of interest and will hereafter 

 be published. — Ed. 



SHORT ARTICLES. 



Heredity of fasciations. — In a highly interesting article, 

 which appeared in Vol. VI., 1894, of " Het Botanisch Jaarboek," 

 published by " Dodonea," a Botanical Society of Ghent, Belgium. 

 Prof. Hugo de Vries discusses the results of a large number of 

 experiments on Crepis biennis fasciata and other plants, carried on 

 by him, to determine, if possible, the heredity of fasciations. After 

 calling attention to the well-known case of fasciations in Celosia 

 cristata, Professor de Vries goes on to say, that the older teratolo- 

 gists did not consider fasciation to be hereditary, to which opinion 

 the experiments of Gordon* contributed not a little. The latter 

 made a single experiment with but one fasciated plant (Picris 

 hieracioides), and not obtaining fasciation in the second generation, 

 concluded its non-heredity.
