MACLOSKIE, GEO.: Antidromy in plants.—The author 
claims to have discovered two kinds of flowering plants as to

every species there appear to be dextrorse and sinistrorse in- 
dividuals in about equal numbers. This difference is depend- 
ent upon the origin of the ovules being from the right or left 
margin of the carpel and is a primitive character which he 
designates by the term antidromy.
