Friday Fabulous Flower - Gaudy Legume and home at last

Well, in the wee hours of Friday the Phactors finally got home; spent the entire day in the Dallas airport 1st hoping for an earlier (noonish) booking via stand-by, 2nd waiting for a 7pm flight, and finally boarding said flight after a 3 hr delay.  Attitude about airports improved markedly.  Let's hear it for Mesa's antique computer system that was down casuing the delay.  So a bit late with the FFF blog because brain was too fuzzy to do anything much yesterday.  At any rate this gaudy legume shrub is a quite common ornamental in and around Tucson, and for obvious reasons.  TPP must admit to having some confusion here.  He was certain this plant was called Caesalpinia pulcherrima, but then a labelled specimen said Erythrostemon gilliesii.  First thought was that they were actually one species and one name was a synonym of the other.  Although not having researched this in any great depth that does not seem to be the case.  Both species are in the same Caesalpinioid subfamily of the Fabaceae, and both have red/orange flowers, although the former seems more at home in the wet tropics than the desert.  So TPP is unsure of the differences.  If anyone out there knows about any of this, maybe they'll let us know in the comments.
