abaxial clefts 3–8 mm, adaxial 5–9(–12) mm, clefts 30–50% of calyx length, deeper than laterals, lateral (1–)1.5–4(–5) mm, 10–25% of calyx length;

lobes lanceolate to oblong, abaxials wider than adaxials, apex acute to rounded.

colored as bracts, (18–)21–35(–38) mm;

Discussion

Varieties 3 (3 in the flora).

Much confusion exists concerning Castilleja angustifolia and the closely related C. chromosa. Sometimes C. chromosa is treated as a variety of C. angustifolia, using the name C. angustifolia var. dubia. The latter name is used here to represent a different assemblage of plants, not including C. chromosa. At other times, C. chromosa is synonymized completely under C. angustifolia. However, the two species are in most cases easily separable, and where they are sympatric there is little evidence of intergradation. Both C. angustifolia var. dubia and C. chromosa are accepted here. See additional comments under 3b. C. angustifolia var. dubia and 15. C. chromosa.

Castilleja integra is widespread and common in the southwestern United States. It is important to Native Americans for dyes, ceremonies, as a food preservative, and as a medicine. It is sometimes confused with C. lanata or C. miniata but has a distinctive combination of entire, narrow, strongly involute leaves, soft-tomentose pubescence of unbranched hairs, and usually entire bracts, sometimes with one pair of short lobes from the middle. The leaf margins of C. integra are usually plane, but some populations in the Chisos Mountains of Texas are wavy margined. These plants are on the higher slopes of the Chisos Mountains in montane thorn-oak vegetation, and they are also often taller and have longer, more frequently lobed leaves. These variant populations have been called C. elongata, and they deserve further study. Castilleja integra is typically a species of dry grasslands and open forests at moderate elevations. Occasional hybrids with C. linariifolia are known from Montrose County, Colorado.

The Castilleja elongata form of C. integra is in the Center for Plant Conservation’s National Collection of Endangered Plants.
