Brickellia knappiana Drew
Habit: Shrub 100--200 cm. Stem: arching, branched from near base, gland-dotted. Leaf: alternate, petiole 4--5 mm, blade 10--35 mm, 1--16 mm wide, lanceolate to lance-ovate, dentate to serrate, base acute to attenuate, tip acute to acuminate, faces densely gland-dotted and sparsely puberulent or hairy, not appearing glossy or varnished. Inflorescence: heads in panicle-like clusters, peduncle 2--5 mm, densely short-hairy and glandular, involucre 6--9 mm, cylindric to narrowly bell-shaped; phyllaries 18--22, in 5--7 series, 3--4-striate, tip acute to acuminate, margin scarious; outer lance-ovate, sparsely puberulent, gland-dotted, inner lanceolate, glabrous. Flower: 5--7; corolla 5--6.5 mm, white. Fruit: 2.5--3, puberulent to sparsely hairy; pappus bristles 28--32.
Ecology: Gravelly washes; Elevation: 700--1700 m. Bioregional Distribution: n&e DMtns (Panamint, n Kingston, Funeral, sw Argus ranges), DSon. Flowering Time: Sep--Oct Note: Possibly a hybrid between Brickellia californica and Brickellia longifolia var. multiflora or between Brickellia desertorum and Brickellia longifolia.
Unabridged Note: Brickellia knappiana is noted as a possible hybrid between Brickellia californica and Brickellia multiflora (= Brickellia longifolia var. multiflora) or between Brickellia desertorum_ and Brickellia longifolia. Collections from mixed populations of Brickellia knappiana and Brickellia californica have been noted on herbarium specimens. Collections of specimens assignable to Brickellia knappiana that I have made have been where populations of Brickellia longifolia var. longifolia_and Brickellia desertorum intersect.
