_Pentstèmon Wrìghtii_

Spring

Arizona=]

This is very much like the last in every way, except the color of

its flowers. The leaves are smooth and thickish, bluish-green, with

a "bloom," the lower ones with a few irregular, blunt teeth, or with

wavy margins, and the flowers, which are the same shape and size as

the last, are deep, bright pink, with a magenta line on each lobe and

some white hairs on the lower lip. The filaments are purple, with

whitish anthers, and the fifth stamen resembles a tiny brush, with

yellow bristles on the upper side and pointing into the throat. The

whole effect of the graceful flower-cluster is bright, beautiful, and

conspicuous, growing among the rocks, on hillsides and in canyons.

_Pentstèmon laètus_

=Blue, purple

Summer

California=]

This is very beautiful and varied in color and is the commonest kind in

Yosemite, from one to two feet high, with roughish, toothless leaves

and several slender, erect, somewhat hairy branches, ending in long

loose clusters of flowers. The corollas are an inch long, and vary from

deep bright blue through all shades of violet to deep pink, with two

white ridges in the throat, and with two white anthers visible and two

purple ones hidden in the throat. The flowers' faces have a quaint,

wide-awake expression. This grows on dry rocky slopes and is often

mistaken for _P. heterophýllus_, which is rather common in open places

in the Coast Ranges. _P. linarioìdes_, blooming in late summer at the

Grand Canyon, is somewhat similar, but the flowers are smaller and more

delicate, and the leaves are smooth, small, and narrow.

[Sidenote: =Scarlet Bugler=

_Pentstèmon Èatoni_

=Red

Spring

Ariz., Utah=]

Very beautiful, from two to three feet high; with purplish stems,

smooth leaves, and flowers an inch long, with a bright scarlet,

funnel-shaped corolla, not much two-lipped, the stamens not protruding.

These graceful wands of vivid color are conspicuous in the Grand

Canyon. _P. centranthifòlius_, common in California, is similar, the

corolla less two-lipped, and has very smooth, thickish leaves. _P.

Bridgésii_, found in Yosemite, is similar, but the corolla is decidedly

two-lipped.
