T. Daniel in email of 8 Jan. 2015 first thought this to be Justicia pringlei. He later changed to J when I mentioned that Allen Coombes had suggested that. The latter is also more in accord with the habitat. First email of 8 Jan: I am working at home today, so I can't check all my files, but your plant sure looks to be Justicia pringlei. Itis always nice to get---in fact that unicate would be great to verify because I just checked my files here and I see that J. pringlei has not been previously collected in Puebla! Justicia pringlei is identical (morphologically) to the federally listed (endangered) species, J. cooleyi, in Florida. I recently treated them as conspecific, and I subsequently had a student intern working on DNA sequence data for these and several other similar plants from South America. We still need to find a more variable locus to be certain at this point about the taxonomy, but J. pringlei is reasonably widespread in Mexico (though rarely "common") and is the oldest name in the complex. Then in a second email from the same day: "Yes, sure could be and probably is J. pectoralis, especially if it was collected in or around water or very wet ground. J. pringlei is on dry ground, most often in pine forest. Similar shape, size, and color for corollas in both species. The major distinctions are: anther cells lacking appendages in J. pectoralis (vs. lower cell with prominent basal appendage in pringlei), calyx 5-lobed and 2-3.5 mm long in pectoralis (vs. 4-lobed and 5-8.5 mm long in pringlei), seeds covered with knoblike tubercles but lacking trichomes in pectoralis (vs. seeds pubescent with terminally barbed and very conspicuous trichomes in pringlei). I should not try to identify images at home where I do not have everything I need! But, I am sure that J. pringlei occurs in Puebla and will eventually turn up in collections from there.
