[Sidenote: =Castilleja pallida= Kunth. _White Indian Paint-brush._] Commonly hairy with weak cobwebby hairs, a foot or less high. Leaves linear to lanceolate or the upper ovate-lanceolate. Flowers in dense leafy-bracted spikes; bracts oval or obovate, partly white or yellowish, cobwebby-hairy, equalling the corolla; calyx 2-cleft, the lobes oblong or lanceolate, corolla ½—1 inch long; galea not exceeding the calyx.
