Raised from seeds brought home by Mr. Hartweg in Juno, 1848, and said to be a shrub four feet high, from the mountains of Santa Ines, in California.
A downy-stemmed half-shrubby plant, with a trailing or spreading habit, so that it is well suited to hang down over stones or rocks. Leaves dark green, shining, cordate, serrate, slightly downy. Flowers in onesided, narrow, leafy panicles, which sometimes measure more than a foot in length. The branches of the panicle are hairy, and bear each from three to five flowers when the plants are vigorous. Calyx cov-ered with glandular hairs; corolla not quite an inch and a half long, rich dull red; the tube almost cylindrical; the upper lip straight, nearly flat, slightly two-lobed; the lower three-parted, spreading at right angles to the upper.
It has so little the appearance of a Pentstemou that it may be expected to be regarded hereafter as a distinct genus.
A hardy little shrub, growing freely in any good rich garden soil, and easily increased by seeds or cuttings in the usual way. It flowers freely, one year from seeds, and lasts in flower from June to October.
It is a very desirable, hardy plant. - Horticultural Society's Journal.
