Rank Reasons
Penstemon pinifolius occurs in southeastern Arizona and southwestern New Mexico, and in Mexico in the Sierra Madre Occidental in Chihuahua and Sonora states, and in the Sierra Madre Oriental in Hildago and Querétaro states. It also occurs in Tamaulipas state (SEINet 2018, Villaseñor 2016). It has a fairly large range in Mexico, but the populations are better documented in the USA ((SEINet 2018, NatureServe Network Database as of November 2018), the amount of threat is low.
Range Extent Comments
Penstemon pinifolius occurs in southeastern Arizona in the Chiricahua Mountains. It occurs in the Mogollon Mountains in easternmost Arizona and mainly New Mexico, and in southwestern New Mexico in the Black Range, Pinos Altos Mountains, Animas Mountains, Cooke's Range, San Mateo Mountains, and Magdalena Mountains (Allred and Ivey 2012, SEINet 2018). In Mexico, Penstemon pinifolius occurs in the Sierra Madre Occidental in Chihuahua and Sonora states, and in the Sierra Madre Oriental in Hildago and Querétaro states. It also occurs in Tamaulipas state (SEINet 2018, Villaseñor 2016).
Occurrences Comments
There are estimated to be 200 occurrences (SEINet 2018). Over 100 collections have been made in New Mexico, but some of these are from the same locations (SEINet 2018).
Threat Impact Comments
In areas where Penstemon pinifolius occurs which are grazed by livestock, over grazing may be a threat. Severe droughts are a threat, these may be associated with climate change.
Ecology & Habitat

Description

Plants herbaceous or woody only at the base, leaves small, needlelike, linear or broader, less than 35 mm long. The corollas are red, 25-32 mm long, tubular, strongly bilabiate; the inflorescence is secund, glandular; the anthers are explanate, glabrous; the staminode bearded most of length with bright yellow hairs; base of lower lobes with long, flat, yellow hairs (Allred and Ivey 2012, Bleakly 1998).

Diagnostic Characteristics

Penstemon pinifolius plants are herbaceous or woody only at the base, the leaves are less than 35 mm long, needlelike, linear or broader, and crowded at the lower part of the stem. The tubular corollas are red or orange-red (on some plants yellow), 25-32 mm long (Allred and Ivey 2012, Bleakly 1998).

Habitat

Penstemon pinifolius grows in rocky areas in mountains and foothills (Allred and Ivey 2012). In the Sierra Madre Occidental, it occurs in oak woodlands, oak-pine woodlands, pine-oak-juniper woodlands, and mixed conifer forests associated with Pseudotsuga, Pinus, Robinia, Chenopodium graveolens, Galium, Aguilegia, Oxalis, Thalictrum, and Artemisia (SEINet 2018). In SW New Mexico and SE Arizona it occurs in canyons, on dry mountainsides, rocky cliffs, outcrops, ledges and summits, rocky roadsides, in montane conifer forests (Spruce, Fir, Douglas-fir), mixed forests, Ponderosa pine-oak forests, Ponderosa pine woodlands, and riparian forests. Associated species include Pinus ponderosa, Pinus strobiliformis, Pinus cembroides, Pinus edulis, Cupressus arizonica, Juniperus deppeana, Quercus rugosa, Quercus gambelii, Populus tremuloides, Platanus wrightii, Agave parryi, Juglans, Cercocarpus, Fendlera, Philadelphus argenteus,Commelina dianthifolia, Oxalis, Saxifraga, Echinercereus, Arabis perennans, Bahia dissecta, Bouteloua curtipendula, Cheilanthes wootoni, Eriogonum jamesii, Milla biflora, Comandra pallida, Heuchera, Agave parryi, Senecio eremophilus ssp. macdougalii, Silene laciniata, Erysimum capitatum, Acer glabrum, Vitis arizonica, and Acer negundo (SEINet 2018).
