Leaves needle-like, 38 to 1 in. long, sharply pointed, narrowed at the base to a short indistinct petiole, glabrous. Flowers borne in August in terminal racemose or narrowly paniculate inflorescences 2 to 412 in. long, on pedicels 18 to 316 in. long, densely glandular-downy. Calyx about 316 in. long, divided to about half-way into five narrow, triangular-acute or ovate, long-apiculate lobes, glandular-downy. Corolla about 1 in. long, scarlet, narrowly tubular at the base, divided at the top into five oblong lobes rounded at the apex, three of them narrow, the other two broader. Stamens exserted from the throat but overtopped by the lobes. Ovary glabrous; style slender, exserted beyond the stamens.
