ABSTRACT
Portulaca rubricaulis H.B.K. occurs mainly in the Antilles but ranges from Florida to the northern portion of South America. Previously, there were only a few reports of its presence in the Yucatan Peninsula but a recent revision of the Mexican herbaria CICY, ENCB, MEXU, UCAM and XAL reveals that the species is widely distributed and well collected in the Peninsula's northern territory. Furthermore, some specimens from the southwestern part of the Mexican state of Campeche were encountered, suggesting the possibility that P. rubricaulis is currently expanding its range southward in the Peninsula toward the southern coasts of the Gulf of Mexico. In addition, in the present paper an identification key to the known species of Portulaca for the Yucatan Peninsula is provided.
