This is from the same location as Liz's shots, but I think her plants were less advanced, so the inflorescence had not branched yet. Leaves are sessile, so has to be bonariensis or incompta. Then the corolla clearly exceeds the calyx by a good long way, making it bonariensis, but as for the glands.... I had it back out of the press and under the microscope at 40X magnification and might have been able to make out some sessile glands lurking among all the non-glandular hairs, but they were pretty subtle. Not a feature I would have chosen to use in a key! I'll work on getting some incompta later.
