A single dwarf individual was discovered in a bed of plants from 
commercial seed of Portulaca grandiflora. When the dwarf is selfed 
it throws all dwarfs. Some of the dwarf offspring produce reverting 
branches which differ from the dwarf stock upon which they are 
borne by having red, instead of green stems and by having longer 
internodes. The flowers on both dwarf stock and reverting branches 
are red. Selfed seed from the reverting branches produces both 
dwarfs with short internodes and normal plants with long internodes 
as well as occasional dwarfs that show reverting branches.
