Taxonomy: The name Castilleja angustifolia was included in TJM (1993), but those populations were assigned to the name C. chromosa in TJM 2 (2012). Castilleja angustifolia var. flavescens differs from C. chromosa in having inflorescence bracts that are usually tipped with pink, reddish-pink, yellow, yellow-orange, or white (often variable within a population) vs usually bright red, scarlet, or orange red. Additionally, the corolla beaks in var. flavescens are 8–15 mm long vs 9–18 mm long in C. chromosa. |
