Discussion
Portulaca grandiflora is naturalized in gardens and has escaped to roadsides and waste places. Studies of seed surfaces from specimens representing 100 years of collections with distribution over the United States show remarkable consistency in seed morphology. Tubercles may extend onto the lateral surface, where they are widely scattered. Only one specimen was found with no tubercles at all.
Selected References
None.
