(Greek for tortoise or turtle: the corolla fancied to resemble a reptile's head). Scrophulariaceae. Turtle-Head. Several North American perennial herbs, with showy flowers in short spikes or in panicles, some of which are now sold by dealers in native plants. Allied to Pentstemon.

Upright smooth branching plants: corolla more or less 2-lipped or gaping, white or red, the upper lip arched and conspicuous and notched; anthers 4, woolly, and a rudiment of a fifth stamen: seeds winged: leaves opposite, serrate. - Four species, in N. Amer.

Half-shaded places are preferable for these easily cultivated plants. Very dry grounds should be avoided, from the fact that they are best in swampy places. In the ordinary border they should have a very liberal mulch of old manure in their growing season: 4-5 in. thick is none too much: the surface roots will feed in this compost, and the plants are not so liable to suffer from drought when thus protected. (J. B. Keller.)
