Raceme of pink mountain pride flowers
showing their “bearded tongues”
Various penstemon species are native to
the Sierra Nevada. Newberry's penstemon
(Penstemon newberryi), commonly known as
mountain pride, is one of them [1-3].
This wildflower typically grows on rocky slopes at a broad
elevation range. The shown plant was
found in the Tahoe National Forest
on a hike to the
Salmon
and
Loch Leven lakes
along a mid-elevation section of the
Loch Leven Trail.
The deep pink flowers are usually turning to one side in a
short raceme; in contrast to other penstemons such as
Wilcox's penstemon with a whorl of flowers.
Each tubular flower opens with a two-lobed upper and a three-lobed
lower lip.
Two lower ridges inside the corolla and four of the five
anthers are hairy; giving the impression of bearded tongues
playing wild in the corolla-mouth. Due to this interesting feature
of penstemons, the name beard-tongue is
synonymously employed.
A mountain pride plant can reach a height of 30 cm
(12″). Along the erect, rounded, rhubarb-colored stem
grow opposite leaves—bigger and more dense near the
plant's base.
The leathery, green leaves are lanceolate to ovate in shape,
often with a toothed margin.
Mountain pride looks similar to alpine penstemon
(Penstemon davidsonii), which occurs in the same habitat
and also may have toothed leaves. Alpine penstemon, however, is
a smaller, matted plant with a more bluish flower color.
The genus Penstemon, formerly classified as Scrophulariaceae (Figworth family), is now placed in the family Plantaginaceae in the order Lamiales.
