Tetranema (Greek, four and filament; the genus is characterized by having 4 stamens). Scrophulariaceae. Perennial herbs, grown in the greenhouse. St. very short or in cult. slightly elongated, ascending: lvs. nearly radical, opposite, obovate or oblong, slightly crenate-dentate, base angulate, glabrous: peduncles axillary; scape-like, longer than the lvs., bearing an umbel-like cyme at the top: fls. short-pedicelled, nodding, purple-violet, variegated paler; calyx 5-parted; corolla declinate, posterior lip shortly 2-lobed, anterior larger, 3-cleft; stamens 4: caps. rather compressed, loculicidally dehiscent.—Two species, Mex. and Guatemala. T. mexicanum, Benth., is the only species cult., known as the "Mexican foxglove" and formerly as Pentstemon mexicanus. The pretty fls. are borne in profusion on the summits of slender purple scapes 6-8 in. high. Although essentially a summer bloomer, with good care it may be made to flower most of the year. It is usually regarded as a warmhouse subject, but it makes a good window-plant and is easy to grow. Plants continue to bloom year after year. Prop. by seeds. B.M. 4070. B.R. 29:52.
