LAMOUROUXIA (named after J. V. F. Lamouroux, 1779-1825, a naturalist and professor at Caen). ORD. Scrophularineae. A genus comprising eighteen species of erect, decumbent, or sub-scandent, greenhouse perennial (or rarely annual) herbs, natives of Mexico, Central, and the mountains of South, America. Flowers scarlet or rosy, showy, axillary, or in terminal spikes or racemes; corolla with a short tube, a long, ventricosely compressed throat, and a bilabiate limb. Leaves opposite, toothed or rarely entire, or dissected. It is doubtful if any of the species are now in cultivation; and, as they are probably all more or less root parasites, it is hardly likely they would remain long in gardens after being introduced.
